AB  - The Centaurea genus has great potential in traditional systems and has attracted much interest in the design of novel drug formulations. The present study was focused on the chemical fingerprints and biological properties of Centaurea drabifolia subsp. drabifolia and Centaurea lycopifolia extracts. Spectrophotometric and LC-MS techniques were used to establish the chemical profiles of the studied extracts. Enzyme inhibitory potential was assessed against key enzymes linked to global health problems, namely neurodegenerative diseases (acetylcholinesterase), pigmentation (tyrosinase), and diabetes (α-amylase and α-glucosidase). The antimicrobial propensities of the extract were evaluated against 16 bacterial and fungal strains using the microdilution method. The antioxidant abilities were assessed using DPPH and ABTS radical scavenging, ferric, and cupric reducing powers, phosphomolybdenum, and ferrous metal chelation. The total phenolic compounds varied from 18.33 to 32.84 mgGAE/g extract. Total flavonoid content of the extracts were in the range of 2.88-22.39 mgRE/g extract. Methanol and water extracts showed stronger antioxidant abilities compared to the ethyl acetate extracts. However, the latter extracts were most efficient towards the target enzymes (except for tyrosinase). The water extracts also exerted considerable antimicrobial effects. Findings from the present work tend to support the idea that C. drabifolia subsp. drabifolia and C. lycopifolia may be utilized as effective bio-resources for designing novel health-promoting products or ingredients. It is anticipated that results amassed from this still will open new avenues for research and contribute towards establishing primary data on these species for designing novel phytopharmaceuticals.

AB  - Six wild species (S. alba, S. conoidea, S. dichotoma, S. italica, S. supina, and S. vulgaris) from the Silene genera were tested for potential anti-enzymatic (acetyl cholinesterase (AChE), butyryl cholinesterase (BChE), tyrosinase, α-amylase, and α-glucosidase), antimicrobial (16 microbial strains), and antioxidant activity. An ultra-high performance liquid chromatography-electrospray ionization-tandem mass spectrometry method was used for phytochemical determination. Quinic acid, malic acid, protocatechuic acid, p-coumaric acid, and hesperidin were common in the six Silene species. All extracts showed higher antibacterial effects compared to streptomycin and ampicillin (except S. dichotoma). Antifungal agents, bifonazole (MIC 0.10–0.20 mg/mL and MFC 0.20–0.30 mg/mL) and ketoconazole (MIC 0.15–2.30 mg/mL and MFC 0.20–3.50 mg/mL) showed lower activity than the investigated Silene species extracts. S. alba inhibited AChE (2.00 mg GALAE/g extract) and BChE (1.0 mg GALAE/g extract). The results showed metal chelating potential ranging from 12 to 19 mg EDTAE/g extract, with S. conoidea being the most active, and S. supina the least. S. dichotoma showed the highest reducing potential against both cupric (154 mg TE/g extract for CUPRAC) and ferric (102 mg TE/g extract for FRAP) ions. Overall, Silene species could be considered as emerging interesting functional foods and sources of nutraceuticals with applications in the management of different diseases.

AB  - Ballota macrodonta Boiss. et Balansa., is a traditionally used endemic medicinal plant used to manage a plethora of diseases in Turkey. Nonetheless, few studies have endeavoured to highlight its therapeutic potential and its phytochemical profile. We hypothesized that B. macrodonta would possess multi-pharmacological propensities and bioactive compounds that would justify its use as a folk remedy. Aerial part of B. macrodonta was assessed for its antioxidant, antimicrobial, and enzymatic inhibitory potential using different extraction solvents. The total bioactive components determination and compound identification using High-Performance Liquid Chromatography with Diode-Array Detection (HPLC-DAD) method were used to correlate the biological properties. HPLC-DAD profile showed the presence of 19 components (e.g. hydroxybenzoic acid, catechin hydrate, vanillic acid, caffeic acid, syringic acid, epicatechin, coumaric acid, ferulic acid, luteolin-7-O-glucoside, rutin, and quercetin). The water and methanolic extracts showed high total phenolic and flavonoid contents, respectively. The overall antioxidant capacity of the water extract was higher than the one of the methanol extract. The extracts showed inhibitory activity against cholinesterases, tyrosinase, α-amylase and α-glucosidase. The extracts also presented antimicrobial activity against eight Gram positive/negative bacteria (MIC – 0.05–0.15 mg/mL) and eight fungi (MIC – 0.0125–0.20 mg/mL). The presence of active biomolecules with multi-pharmacological properties makes B. macrodonta a potential source of health-promoting compounds that can be exploited as a novel medicinal herbal product.

AB  - Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the biological and chemical profiles of different extracts (ethyl acetate, methanol and water) obtained from three Achillea species (A. biebersteinii, A. millefolium and A. teretifolia). The antioxidant (free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), metal chelating and phosphomolybdenum), enzyme inhibitory (anti-cholinesterase, anti-tyrosinase, anti-amylase and anti-glucosidase) and antimicrobial (antibacterial and antifungal) effects were assessed to investigate their biological profiles. Moreover, the total phenolic and flavonoid contents were determined and LC-MS analysis was performed for the chemical profile of the investigated extracts. The LC-MS analysis revealed the presence of several caffeoylquinic acids in these extracts. Generally, the methanol and water extracts exhibited stronger antioxidant abilities, which correlated with the higher levels of phenolic compounds when compared to the ethyl acetate extracts. In addition, the best antimicrobial activities were obtained for the ethyl acetate and methanolic extracts. However, the ethyl acetate extract had remarkable enzyme inhibitory potential. On the basis of our results, Achillea species may be promoted as promising sources of natural agents and used for the development of nutraceuticals or functional food ingredients.
