AB  - In recent years, the interest in products of natural origin has boosted the exploitation and use of plants as food and sources of bioactive compounds, especially wild plants widely used in different cultures for several purposes. Commelina erecta is a wild edible plant (WEP) traditionally used as food and medicine, about which few studies exist. Thus, this study aimed at enhancing the knowledge about its nutritional, chemical and bioactive profile, considering different plant parts and development stages, in order to increase its inclusion in the diet of South American communities. The nutritional profile was found to be similar to other WEP frequently consumed in Brazil. Thirteen phenolic compounds (HPLC-DAD-ESI/MS) were tentatively identified, with apigenin, luteolin and quercetin derivatives being the most abundant. Fructose and oxalic acid were the major sugar and organic acid, respectively, in the aerial parts of C. erecta, and four isoforms of tocopherols were also identified. Regarding the plant's antioxidant activity, the EC50 values varied between 18.4 and 1060 µg/mL in the inhibition of lipid peroxidation assay (TBARS) and between 53 and 115 µg/mL in the oxidative haemolysis inhibition (OxHLIA) assay. The hydroethanolic extract obtained from stems at the flowering stage also presented anti-inflammatory activity. In general, all the extracts evidenced promising antimicrobial activity. Altogether, these results reinforce the traditional use of this plant species as food and medicine to support the diet of needier populations and also promote food sovereignty and sustainability.

AB  - Chemical constituents and bioactive properties of rambutan (Nephelium lappaceum L.) peel were characterized and heat-/ultrasound-assisted extractions (HAE/UAE) of anthocyanins were optimized by response surface methodology. Five organic acids, the α-, γ-, and δ-tocopherol isoforms, and twenty-five fatty acids (36.8 % oleic acid) were identified, as well as a phenolic profile composed of ellagitannin derivatives, geraniin isomers, ellagic acid, and delphinidin-O derivatives. The extract showed antioxidant activity via lipid peroxidation (IC50 = 2.79 ± 0.03 µg/mL) and oxidative hemolysis (IC50 = 72 ± 2 µg/mL) inhibition, and displayed antibacterial and antifungal properties (MIC ≤ 1 mg/mL). On the other hand, no cytotoxicity was observed in tumor and non-tumor cell lines up to 400 µg/mL. The recovery of anthocyanins was more effective using HAE than UAE, allowing greater yields (16.2 mg/g extract) in just 3 min and using lower ethanol proportions. Overall, rambutan peel could be upcycled into bioactive ingredients and natural colorants for industrial applications.

AB  - Wild thyme aerial parts (Serpylli herba) are recognized as a valuable herbal product with antioxidant, anti-inflammatory, and antibacterial effects. Although pharmacopoeial regulations allow its collection exclusively from Thymus serpyllum, substitution with other species is frequent in current practice. This study analyzed the phenolic composition, antioxidant, and enzyme-inhibitory and antimicrobial activity of the hydroethanolic extracts obtained from five Romanian wild thyme species (Thymus alpestris, T. glabrescens, T. panonicus, T. pulcherimus and T. pulegioides). The analysis of individual phenolic constituents was performed through LC-ESI-DAD/MS2, while for the in vitro evaluation of antioxidant potential, TEAC, FRAP, DPPH, TBARS and OxHLIA assays were employed. The anti-enzymatic potential was tested in vitro against tyrosinase, α-glucosidase and acetylcholinesterase. High rosmarinic acid contents were quantified in all species (20.06 ± 0.32–80.49 ± 0.001 mg/g dry extract); phenolic acids derivatives (including salvianolic acids) were confirmed as the principal metabolites of T. alpestris and T. glabrescens, while eriodictyol-O-di-hexoside was found exclusively in T. alpestris. All species showed strong antioxidant potential and moderate anti-enzymatic effect against α-glucosidase and acetylcholinesterase, showing no anti-tyrosinase activity. This is the first detailed report on the chemical and biological profile of T. alpestris collected from Romanian spontaneous flora.

AB  - A variety of the classic green tea plant, Camellia sinensis, was developed and is exclusive to Kenya. Due to high content of anthocyanin polyphenols in its leaves, the beverage obtained from this variety is purple in color and is the origin of the name purple tea. This work had two main purposes. The first one was to identify and quantify the major anthocyanin polyphenols in a hot water aqueous extract of the purple tea leaves. The second one was to test the hypothesis if this extract is capable of inhibiting triglyceride absorption considering that anthocyanin polyphenolics have been frequently associated to antilipidemic effects. Parallel experiments were always done with a similar green tea extract for comparison purposes. The antioxidant, anti-inflammatory, and cytotoxic activities of both tea varieties are similar. The purple tea extract, however, was strongly inhibitory toward the pancreatic lipase (minimal IC50 = 67.4 μg mL-1), whereas the green tea preparation was a weak inhibitor. Triglyceride digestion in mice was inhibited by the purple tea extract starting at 100 mg kg-1 dose and with a well-defined dose dependence. Green tea had no effect on triglyceride digestion at doses up to 500 mg kg-1. The latter effect is probably caused by several components in the purple tea extract including non-anthocyanin and anthocyanin polyphenols, the first ones acting solely via the inhibition of the pancreatic lipase and the latter by inhibiting both the lipase and the transport of free fatty acids from the intestinal lumen into the circulating blood. The results suggest that the regular consumption of Kenyan purple tea can be useful in the control of obesity.

AB  - Several scientific studies have been proving the bioactive effects of many aromatic and medicinal plants associated with the presence of a high number of bioactive compounds, namely phenolic compounds. The antioxidant, anti-inflammatory, and antimicrobial capacities of these molecules have aroused high interest in some industrial sectors, including food, pharmaceuticals, and cosmetics. This work aimed to determine the phenolic profiles of the infusions and hydroethanolic extracts of five plants (Carpobrotus edulis, Genista tridentata, Verbascum sinuatum, Cytisus multiflorus, and Calluna vulgaris) that have been employed in many traditional preparations. In addition, the antioxidant, antimicrobial, anti-inflammatory, and anti-tumoral activity of each different preparation was evaluated using in vitro assays. The HPLC-DAD-ESI/MS profile revealed the presence of eighty phenolic compounds, belonging to seven different families of compounds. Regarding antioxidant properties, the hydroethanolic extract of C. edulis showed a potent effect in the TBARS assay (IC50 = 1.20 µg/mL), while G. tridentata hydroethanolic extract achieved better results in the OxHLIA test (IC50 = 76 µg/mL). For cytotoxic and anti-inflammatory results, V. sinuatum infusions stood out significantly, with GI50 = 59.1-92.1 µg/mL and IC50 = 121.1 µg/mL, respectively. Finally, C. edulis hydroethanolic extract displayed the most relevant antibacterial activity, showing MBC values of 0.25-1 mg/mL, while G. tridentata hydroethanolic extract exerted the greatest antifungal effects (MFC of 0.5-1 mg/mL). The results of this study deepen the knowledge of the phenolic profiles and also provide evidence on the bioactive properties of the species selected, which could be considered highly valuable options for research and application in several sectors, namely food, cosmetics, and pharmaceuticals.

AB  - The cosmetic industry is constantly searching for bioactive ingredients, namely, those obtained from natural sources with environmentally friendly connotations and less toxic effects. A previous study of our research group optimized the extraction of phenolic compounds from Juglans regia by heat-assisted extraction. Due to its richness in different phenolic compounds, the present work aimed to develop a formulation containing J. regia leaf extract. The extract's antioxidant, anti-tyrosinase, antimicrobial, anti-inflammatory, wound healing, cytotoxicity, and photostability properties were evaluated. The extract was then incorporated into an O/W base cream, followed by characterization of the final formulation in terms of its antioxidant properties, phenolic composition, and stability over time and at different storage conditions. The most abundant compounds in the hydroethanolic extract were 3-O-caffeoylquinic acid (18.30 ± 0.04 mg/g), quercetin-O-pentoside (9.64 ± 0.06 mg/g), and quercetin 3-O-glucoside (6.70 ± 0.19 mg/g). Besides those, the extract presented antioxidant, anti-inflammatory, wound closure, and antibacterial effects against several skin pathogens. In addition, HaCaT cell viability was maintained up to 98% at 400 µg/mL. Within Proteus vulgaris-infected HaCaT cells, the extract also presented an over 40% bacterial mortality rate at its nontoxic concentration (200 µg/mL). After incorporating the extract, the obtained formulation presented a good physicochemical profile over time and at different storage conditions while also maintaining its antioxidant effect; as such, it can be considered stable for topical application. Future work to evaluate its performance in terms of skin permeation and detailed toxicological studies with a focus on regulatory requirements, involving skin irritation, eye irritation, genotoxicity, photo-irritation, and dermal absorption, should be conducted, as the prepared formulation demonstrated relevant properties that deserve to be further explored.

AB  - Hypericum perforatum L., also known as St. John’s Wort, is recognized worldwide as a valuable medicinal herb; however, other Hypericum species were intensively studied for their bioactive potential. To fill the research gap that exists in the scientific literature, a comparative evaluation between H. alpigenum Kit., H. perforatum L. and H. rochelii Griseb. & Schenk was conducted in the present study. Two types of herbal preparations obtained from the aerial parts of these species were analyzed: extracts obtained through maceration and extracts obtained through magnetic-stirring-assisted extraction. LC-DAD-ESI-MSn analysis revealed the presence of phenolic acids, flavan-3-ols and flavonoid derivatives as the main constituents of the above-mentioned species. Moreover, all extracts were tested for their antioxidant, enzyme-inhibitory and antimicrobial potential. Our work emphasizes for the first time a detailed description of H. rochelii phenolic fractions, including their phytochemical and bioactive characterization. In comparison with the other two studied species, H. rochelii was found as a rich source of phenolic acids and myricetin derivatives, showing important antioxidant, anticholinesterase and antibacterial activity. The study offers new perspectives regarding the chemical and bioactive profile of the less-studied species H. alpigenum and H. rochelii.

AB  - Quince (Cydonia oblonga Mill.) is an astringent fruit widely processed into marmalade and other sweets through processes that discard the peel as a by-product. Therefore, this study was performed to characterize the quince peel composition in nutrients and phytochemicals and evaluate its in vitro biological activity, following a "zero waste" approach. The quince peel dry powder was particularly rich in fiber (20.2 g/100 g), fructose (34 g/100 g), malic acid (7.2 g/100 g), and potassium (692 mg/100 g). Extracts prepared by dynamic hydroethanolic maceration and hot water extraction yielded 4.70 and 4.27 mg/g of phenolic compounds, respectively, with a prevalence of flavan-3-ols. The hydroethanolic extract was the most effective in inhibiting lipid peroxidation and oxidative hemolysis, and also presented better antimicrobial effects against foodborne pathogens, which agreed with the highest flavan-3-ol contents. The extracts were better than control synthetic food additives against some tested fungal and bacterial strains. On the other hand, no ability to inhibit nitric oxide production or toxicity to the tumor and non-tumor cell lines was observed. Furthermore, the solid residues remaining after extraction contained 35-37 g/100 g of fiber. Overall, quince peel can be upcycled into fiber-rich and bioactive ingredients to endow the value chain with natural food fortifiers, preservatives, and health promoters.

AB  - Cardoon (Cynara cardunculus var. altilis) blades were collected at sixteen sampling dates (B1-B16) to study the influence of the phenological growth stage on the phenolic composition and biological properties. Twenty phenolic compounds were identified, among which trans 3,4-O-dicaffeoylquinic acid, 5-O-caffeoylquinic acid, and luteolin-O-hexoside (39.6, 42.6, and 101.0 mg/g extract, respectively) were the main compounds. Immature blades (B3) had a higher content of phenolic compounds (178 mg/g extract) and a greater ability to inhibit the formation of thiobarbituric acid reactive substances (IC50 of 1.61 µg/mL). Samples at more advanced growth stages revealed a greater capacity to inhibit oxidative hemolysis (B8, IC50 of 25 and 47.4 µg/mL for Δt of 60 and 120 min, respectively) and higher cytotoxic (B8-B13, GI50 between 7.1 and 17 µg/mL), anti-inflammatory (B13, IC50 of 10 µg/mL), and antibacterial activities. In turn, the antifungal activity varied depending on the tested fungi. All these results suggest that maturity influences the phenolic composition and bioactive properties of cardoon blades, which reveal great potential for the development of bioactive ingredients for food and pharmaceutical applications, among others.

AB  - Despite the significant advances in drug development we are witnessing the inability of health systems to combat both neurodegenerative diseases and cancers, especially glioblastoma. Hence, natural products are comprehen-sively studied in order to provide novel therapeutic options. This study aimed to explore anti-neurodegenerative and anti-glioblastoma potential of extract of Phlomis fruticosa L. using in vitro model systems. It was found that the methanol extract of P. fruticosa was able to efficiently reduce activities of enzymes linked to neurodegenera-tive disease including acetylcholinesterase, butyrylcholinesterase and tyrosinase. Furthermore, P. fruticosa extract has shown excellent antioxidant potential, as evidenced by six different methods. Analysis of cytotoxic effect of P. fruticosa extract on A172 glioblastoma cell line revealed that the concentration of the extract necessary for 50 % inhibition of A172 growth (IC50) was 710 μg/mL. The extract did not induce changes in proliferation and morphology of A172 glioblastoma cells. On the other side, production of ROS was increased in A172 cells treated with the extract. Observed cytotoxic effect of P. fruticosa extract might be based on increase in ROS generation upon treatment. Quantitative chemical analysis revealed the presence of twelve different polyphenols with the cis 3-O-caffeoylquinic acid being the most abundant. This study provided scientific evidence for further exploration of P. fruticosa as a promising natural anti-neurodegenerative therapeutic option.

AB  - Cytinus hypocistis (L.) L. is a comestible holoparasite with great potential for cosmeceutical application. Although its high tannin content has been associated with its bioactive and inhibitory enzyme properties, this is the first report establishing a relationship between parasite and host (Halimium lasianthum (Lam.) Greuter) phenolic profile and bioactive properties. Thus, five extracts (aerial and root extracts of non-parasited and parasited H. lasianthum and C. hypocistis) were evaluated. The tentative identification of both species comprises 39 phenolic compounds. Hydrolysable tannins and flavonoids were the main identified groups in C. hypocistis and H. lasianthum extracts, respectively. Regarding bioactivities, C. hypocistis exhibited excellent antioxidant results both in Oxidative Haemolysis (OxHLIA) and inhibition of Thiobarbituric Acid Reactive Substances Formation (TBARS). The tested extracts presented antimicrobial inhibition, anti-inflammatory activity, and effective cytotoxicity against tumour cells. C. hypocistis exhibited the lowest cytotoxicity on a non-tumour cell line. Principal Component Analysis (PCA) was a suitable approach to analyse differences among samples, explaining up to 67% of data variability and suggesting no similarities between parasite and host phenolic composition and bioactivities. Therefore, this comparative study emphasises the significance of both species as a source of biologically active compounds.

AB  - Leaves and barks of Luehea divaricata (Malvaceae) are used in folk medicine for the treatment of infectious diseases, tumors, rheumatism and diabetes. This work presents in vivo experiments (rats and mice) supported by in vitro and chemical analyses in order to address the above mentioned folk medicinal uses. The phenolic constituents of both aqueous and hydroalcoholic extracts are mainly catechin derivatives (135.4 and 215.9 mg/g, respectively). Both extracts displayed strong antioxidant activity. They also showed antiproliferative activities against tumor cells, nitric oxide synthesis inhibition (indicative of anti-inflammatory activity) and antimicrobial activity against a variety of infectious agents. Paracetamol-induced liver injury in rats, which has a high inflammatory component, was substantially attenuated in animals treated with the hydro-alcoholic extract (200 mg kg−1 day−1). This was deduced from aspartate aminotransferase and alanine aminotransferase measurements in plasma as well as from the hepatic activities of catalase and superoxide dismutase. Both extracts inhibited the pancreatic α-amylase with IC50 values of 11.50 ± 0.05 and 18.70 ± 3.87 μg/mL for the hydro-alcoholic and aqueous extract, respectively. Both extracts inhibited starch digestion in mice at the doses of 200 and 400 mg/kg. In general terms the results confirm several of the vox populi notions about the therapeutic potential of L. divaricata, the antidiabetic action, combined with the hepatoprotective effect, being the most relevant observations. Not less important is the economical perspective for the rural producers which may eventually increase their revenue by selling increasingly valued raw materials derived from L. divaricata based on its therapeutic properties.

AB  - Cynara cardunculus L. (cardoon) is a typical Mediterranean species that comprises the ancestor wild
cardoon (var. sylvestris), the cultivated leafy cardoon (var. altilis) and globe artichoke (var. scolymus). It
can be found worldwide due to its high adaptability to diverse climate conditions (e.g., resistance to extreme
temperatures, water stress, and soils with variable pH) [1,2]. It is also considered a multipurpose crop due
to its nutritional, pharmacological and industrial applications [2]. Due to the increase of its commercial and
economic value, this study aimed to evaluate the polyphenolic composition and bioactive potential of
cardoon bracts in relation to plant growth cycle. Cardoon bracts were collected in central Greece at eight
different maturation stages (samples C1 – lower maturity to C8 – higher maturity). The phenolic profile was
determined by HPLC-DAD-ESI/MS. The antioxidant activity was measured through two cell-based assays:
TBARS (thiobarbituric acid reactive substances formation inhibition) and OxHLIA (oxidative hemolysis
inhibition). Cytotoxic effects were screened against four human tumor cell lines and hepatotoxicity against
a non-tumor cell line (PLP2) by the sulforhodamine B assay. The anti-inflammatory potential was tested
through the inhibition of NO production by a murine macrophage cell line (RAW 264.7). Finally, the
antibacterial and antifungal activities were evaluated by the broth microdilution method. Twelve phenolic
compounds were tentatively identified in the cardoon bract extracts and quantified in higher amounts in
immature samples. Immature bracts (C1) also revealed the highest cytotoxic (GI50 of 30 – 79 μg/mL) and
anti-inflammatory (IC50 = 72 μg/mL) activities, while they presented the highest capacity to efficiently
inhibit the formation of TBARS (IC50 = 26.8 μg/mL). In contrast, the extract with the higher maturity grade
(C7) revealed superior efficacy against oxidative hemolysis (IC50 of 38 and 75 μg/mL at Δt=60 min and 120
min, respectively). The highest antibacterial and antifungal activities were attributed to samples C1 and C6
and samples C2 and C4, respectively. The results obtained in this work could be helpful to choose the best
harvesting time of cardoon bracts, allowing obtaining a greater variety of phenolic compounds, and
consequently, a higher bioactive potential, and ultimately the most appropriate use of their constituents.
Nevertheless, further studies are needed to better understand the compounds responsible for the observed
activities, as well as to reveal the mechanisms involved in these activities.

AB  - Consumers have given preferences to food products that, in addition to the nutritional properties, also present bioactive characteristics with beneficial health effects. The use of Nonconventional Food Plants (NCFP) has been an asset for the food industry, not only due to its abundance but, also, because it does not compete with other vegetable matrices used for human consumption for its nutritional properties, chemical and bioactive potentiality. The present work aimed to study the granulometry and water absorption index of three seeds of unconventional food plants: niger, millet and birdseed, followed by their nutritional value, content in free sugars, fatty acids, organic acids, tocopherols and phenolic compounds by chromatographic methods and, also, the evaluation of the antioxidant, hepatotoxic and antimicrobial potential in their hydroethanolic extracts. Bakery products were developed with a partial replacement of wheat flour, using the centroid simplex method to understand the effect of applying NCFP flours in the final physical–chemical characteristics. The high granulometry associated with the high water absorption index indicates that the use of NCFP flours would have to be complemented with other flours for baking. The chemical composition of niger seed stood out the most; however, all seeds presented relatively low IC50 and MIC values for the inhibition of lipid peroxidation and antimicrobial activity, respectively. Finally, breads made with a mixture of millet and birdseed flour showed the greatest similarity to the control bread. Considering their composition in bioactive compounds, the use of these seeds is highly advisable in the context of a fortified diet, being sources of compounds of high nutritional value and with beneficial health effects for the final consumer.

AB  - Cardoon seeds collected in Greece at four different maturity stages (samples S1 to S4) were analysed in terms of chemical composition and in vitro bioactivities. The content of phenolic compounds (six compounds in total) increased with increasing maturity, and 3,5-O-dicaffeyolquinic (14.8-33.8 mg/g extract) acid was the compound detected in higher abundance. Mature seeds (sample S4) also revealed the highest content in lipids (23 g/100 g extract) and tocopherols (29.62 mg/100 g dw) and demonstrated the highest cytotoxic (GI50 of 97-216 µg/mL) and anti-inflammatory (IC50 = 148 µg/mL) activities, and capacity to inhibit the formation of thiobarbituric acid reactive substances (TBARS) (IC50 = 5 µg/mL). Cardoon seed hydroethanolic extracts also revealed high antibacterial and antifungal potential, particularly samples S3 and S1, respectively. This study proved the multifaceted potential associated with valorisation of cardoon seeds, while their biological and chemical composition can be influenced by the maturity stage.

AB  - The Mediterranean basin is abundant in wild edible species with numerous health beneficial effects due to the presence of various bioactive phytochemicals. In the present work, the effect of nitrogen fertilization rates (0 ppm, (N0), 200 ppm (N1), 400 ppm (N2), and 600 ppm (N3) of total N) and growth substrate composition (soil or peat/perlite (2/1; v/v)) on the chemical composition and bioactive properties of Centaurea raphanina ssp. mixta plants was evaluated. The results of the study showed that both the tested factors affected nutritional value of the edible leaves, with the soil × N1 treatment being the most beneficial for fat, protein, and carbohydrate content and energetic value. On the other hand, the peat/perlite-grown plants that received 200 ppm of N had the highest content in α-, γ-, and total tocopherols, while the control treatment of soil-grown plants was the richest in individual and total sugars. Oxalic, citric, and total organic acids were the highest in the N2 × soil treatment, while malic acid was the highest in control treatment of the same substrate. The main fatty acids were palmitic, α-linolenic, and linoleic acids, with the highest contents being observed in the N0 × soil, N3 × soil, and N3 × peat/perlite treatments, respectively. The major phenolic compounds were pinocembrim neohesperidoside and pinocembrim acetyl neohesperidoside isomer II, with the highest content being observed in the N1 × soil treatment. The highest antihemolytic activity was observed in the N3 × peat/perlite treatment, while the most effective treatments against lipid peroxidation were N0 (in both soil and peat/perlite combinations) and N1 × peat/perlite. Lastly, all the tested extracts (except for N1 × soil) showed promising cytotoxic effects against HeLa (cervical carcinoma), HepG2 (hepatocellular carcinoma), MCF-7 (breast carcinoma), and NCI-H460 (non-small-cell lung cancer), while all the tested extracts exhibited better antifungal activities (lower minimal inhibition concentration (MIC) values) against Trichoderma viride than the positive controls. Overall, the present results suggest that the application of cost-effective practices such as the nitrogen application and the selection of growth substrate may regulate the chemical composition and the bioactive properties of C. raphanina ssp. mixta species and increase its added value under commercial cultivation conditions.

AB  - Given the importance of colour in the general acceptance or rejection of a product, the use of colorants is a widespread practice, particularly in the food industry. At the same time, with the increasing consumers’ awareness of the health effects that some artificial colorants can exert, there is a growing tendency to prioritize foodstuffs containing natural additives. In this work, Morus nigra L. and Rubus fruticosus L. fruit juices were characterized in terms of anthocyanins, organic acids, free sugars, and tocopherols, as also regarding their bioactive properties. Given their richness in anthocyanins, this study also aimed to prepare different solid colouring formulations by the spray-drying technique, using as stabilizers maltodextrin and arabic gum. Six free sugars and two organic acids were detected in the fruit juices, as well as the four tocopherol isoforms. Two cyanidin derivatives were found in M. nigra (cyanidin-3-O-glucoside and cyanidin-O-rhamnoside) and other four in R. fruticosus (cyanidin-O-hexoside, cyanidin-3-O-glucoside, cyanidin-O-pentoside, and cyanidin-3-O-dioxaloilglucoside). The developed colouring formulations revealed a good stability over time, in terms of anthocyanin concentration and colour parameters, and revealed to be safe for consumption, either concerning their low microbial load and lack of cytotoxicity. Thus, they represent a promising natural alternative to the massively used artificial colorants.

AB  - The nutritional quality of kiwifruit has been highlighted by several studies, while its peel is typically discarded as a by-product with no commercial value. This study was carried out to optimize the ultrasound-assisted extraction (UAE) of phenolic compounds from kiwi peel. Three independent variables (time (t), ultrasonic power (P) and ethanol concentration (EtOH)) were combined in a five-level central composite rotatable design coupled with the response surface methodology (RSM). The extraction yield determined gravimetrically and the content of phenolic compounds identified by HPLC-DAD-ESI/MSn (namely two quercetin glycosides, one catechin isomer and one B-type (epi)catechin dimer) were the experimental responses used in the optimization. The polynomial models were successfully fitted to the experimental data and used to determine the optimal UAE conditions. The sonication of the sample at 94.4 W for 14.8 min, using 68.4% ethanol, resulted in a maximum of 1.51 ± 0.04 mg of flavonoids per g of extract, a result that allowed the experimental validation of the predictive model. The kiwi peel extract obtained under optimized conditions showed somehow promising bioactive properties, including antioxidant and antimicrobial effects, and no toxicity to Vero cells. Overall, this study contributes to the valorization of kiwi peel as a low-cost raw material for the development of natural ingredients (such as food preservatives) and also to the resource-use efficiency and circular bioeconomy.

AB  - In the present work, sage (Salvia officinalis L.) and basil (Ocimum basilicum L.) were exploited for their preservative purposes, as viable alternatives to artificial ones. The ultrasound-assisted extraction (UAE) of bioactive compounds was pre-optimized using factorial screening analysis, prior to applying response surface methodology (RSM). The obtained extracts were characterized in terms of phenolic compounds by high-performance liquid chromatography coupled to photodiode array detector and mass spectrometer HPLC-DAD-ESI/MS and bioactivities, namely the antioxidant, antimicrobial and cytotoxic potential. In addition, the most promising extracts were incorporated into yogurts, that were further screened for nutritional and physico-chemical properties and microbial load, over a shelf life of 14 days. According to the obtained results, the solvent percentage is the most relevant factor for obtaining rosmarinic acid-rich extract, followed by the extraction time and ultrasonic power. For the antioxidant and antimicrobial activity, sage showed the best result for both analysis and none of the two plant extracts were hepatotoxic. Finally, both extracts did not show changes in the physicochemical and nutritional characteristics of the yogurts and did not interfere with the growth of lactic acid bacteria, an important microorganism during yogurt fermentation. These results highlight the high potential of sage and basil as natural preservatives.

AB  - The attractive colour characteristics of the flowers of the species Impatiens walleriana have been arousing great interest in the food industry, which is looking for potential natural sources of colouring ingredients. In this sense, the present work focused on the chemical and bioactive characterization of pink and orange flowers of I. walleriana. The phenolic compounds were determined by HPLC-DAD-ESI/MS; in addition, different bioactivities (antioxidant, antimicrobial, anti-inflammatory and cytotoxicity) were also analysed. Both samples studied showed significant amounts of phenolic compounds, especially phenolic acids, flavonoids, and anthocyanins, which justifies the excellent performance in the different bioactivities studied. The orange variety, despite having a greater variety of phenolic compounds, showed a total amount of compounds lower than the pink variety. Overall, the flowers of I. walleriana emerge as a promising resource to be explored by the food industry.

AB  - Muffins are snacks made from flour and chocolate and preserved with synthetic additives. Following consumer trends, the search for natural food additives has gained traction. Plants such as rosemary, lemon balm, and oregano were analyzed following an optimization of ultrasound assisted extraction, screened for their antioxidant and antimicrobial activity and incorporated in chocolate muffins, comparing them to synthetic preservatives over the course of 8 days. The nutritional profile, organic and fatty acids, soluble sugars, texture profile, external color and digital imaging of the muffin pores were analyzed. Slight changes were sought for the muffins incorporated with the natural extracts. By means of linear discriminant analysis, rosemary extract was considered the most promising extract to preserve the muffins due to its similarity to potassium sorbate, showing no changes in the muffins it was incorporated in, although it showed a lower amount of phenolic compounds when compared to lemon balm.

AB  - Cardoon (Cynara cardunculus L.) bracts were collected at different maturation stages to investigate seasonal changes in the phenolic compounds profile and in vitro bioactivities. Among the 12 phenolic compounds tentatively identified, 3,5-O-dicaffeoylquinic acid (21.83 mg/g extract) and apigenin-7-O-glucuronide (10.6 mg/g extract) were the most abundant. Immature bracts (C1: principal growth stage (PGS) 5) had the highest phenolic compounds content, and anti-inflammatory (IC50 = 72 µg/mL) and cytotoxic (GI50 of 30-79 µg/mL) activities. Moreover, extract C1 inhibited efficiently the formation of thiobarbituric acid reactive substances (TBARS; IC50 = 26.8 µg/mL), while extract C8 (PGS 8/9) was more effective against oxidative haemolysis (IC50 38 and 75 µg/mL). The highest antibacterial and antifungal activities were attributed to samples C1 and C6 (PGS 7/8) and samples C2 (PGS 5/6) and C4 (PGS 6/7), respectively. Overall, the obtained results suggest the seasonal changes of polyphenolic composition and bioactivity of cardoon bracts of variable maturity.

AB  - Bryophyllum constitutes a subgenus within the genus Kalanchoe that contains several plant species used in traditional medicine worldwide for the treatment of several diseases. However, little is known about the phytoconstituents of Bryophyllum spp. and previous reports have pointed at their low in Planta concentrations of bioactive compounds. In this work, we take advantage of plant in vitro culture for the study of the phenolic compounds found in the aerial parts of Bryophyllum spp. and their associated bioactivities. Our results show that the induction of nutritional stress leads to an improved accumulation of phenolic compounds, mainly flavonols and anthocyanins, represented by myricetin and malvidin glycosides, respectively. This effect is mainly found for B. × houghtonii, whose hydroethanolic extracts promoted the highest antioxidant, cytotoxic and anti-inflammatory activities. In the case of cytotoxic activity, Bryophyllum extracts showed an enhanced activity against the MCF-7 human breast carcinoma cell line. Meanwhile, extracts from B. daigremontianum promoted a wide range of effectiveness against different bacterial and fungal strains. This study is committed to shed light about the phytochemical potential associated to this unexplored subgenus, with the aim of considering Bryophyllum spp. as a valuable source of bioactive compounds for their exploitation in food, cosmetic and pharmaceutical industries.

AB  - Fruit bio-residues can be interesting for the recovery of bioactive molecules, such as phenolic compounds, tocopherols, vitamins, among others. These compounds can be targeted at the food industry and used for the development of functional foods or as food additives. In some cases, fruit epicarps are converted into by-products with non-commercial value, and generally, these fruit parts have a higher content in bioactive compounds than the fruit pulp. From this perspective, S. odorifera, a Brazilian fruit, has an inedible epicarp that could be explored to obtain biological compounds. Therefore, the aims of this study were to evaluate the chemical composition and the antioxidant, anti-proliferative, anti-inflammatory, and antimicrobial bioactivities of this by-product. S. odorifera epicarp showed a total of four organic acids, four phenolic compounds, highlighting the high concentration of anthocyanins (24 ± 1 mg/g dry weight (dw)) and high content of tocopherols (366 ± 2 mg/100 g dw). The hydroethanolic extract showed considerable antioxidant activity (EC50 values of 48.2 ± 0.5 and 27 ± 1 µg/mL for TBARS and OxHLIA assays, respectively), as also antibacterial and antifungal activities (minimal inhibitory concentrations (MICs) ≤ 2.2 mg/mL). The results obtained in this study suggest that Sicana odorifera epicarp represents a reliable option for the development of novel natural-based colorants with functional/bioactive proprieties.

AB  - Flowers of the genus Impatiens are classified as edible; however, their inclusion in the human
diet is not yet a common practice. Its attractive colours have stirred great interest by the food industry.
In this sense, rose (BP) and orange (BO) I. balsamina flowers were nutritionally studied, followed by
an in-depth chemical study profile. The non-anthocyanin and anthocyanin profiles of extracts of
both flower varieties were also determined by high-performance liquid chromatography coupled
to a diode array and mass spectrometry detector (HPLC-DAD-ESI/MS). The results demonstrated
that both varieties presented significant amounts of phenolic compounds, having identified nine
non-anthocyanin compounds and 14 anthocyanin compounds. BP extract stood out in its bioactive
properties (antioxidant and antimicrobial potential) and was selected for incorporation in “bombocas”
filling. Its performance as a colouring ingredient was compared with the control formulations (white
filling) and with E163 (anthocyanins) colorant. The incorporation of the natural ingredient did not
cause changes in the chemical and nutritional composition of the product; and although the colour
conferred was lighter than presented by the formulation with E163 (suggesting a more natural aspect),
the higher antioxidant activity could meet the expectations of the current high-demand consumer.
