AB  - This research was aimed to assess the potential of Glechoma hederacea, Hyssopus officinalis, Lavandula angustifolia, Leonurus cardiaca, Marrubium vulgare and Sideritis scardica (Lamiaceae) methanolic, ethanolic and aqueous extracts against the damaging effects of oxidative stress using different experimental models. The chemical characterization was done spectrophotometrically by quantifying total phenolics, phenolic acids, flavonoids and flavonols in the extracts, as well as by employing HPLC-DAD technique. Moreover, DPPH assay was used to assess the extracts' radical scavenging potential. Genoprotective properties of the extracts were evaluated using plasmid pUC19 Escherichia coli XL1-Blue, whereas their antigenotoxic potential was determined using Salmonella typhimurium TA1535/pSK1002 and normal human lung fibroblasts. All of the extracts showed antioxidant activity in DPPH assay. Furthermore, the results have shown that aqueous extracts provided the best protection for plasmid DNA, while alcoholic extracts most effectively contributed to the preservation of prokaryotic DNA. Additionally, each of the tested samples significantly protected the eukaryotic cells against genomic damages. Finally, despite not showing exceptional results in DPPH assay, S. scardica extracts are regarded as the most favorable in maintaining the integrity of DNA, which might be due to high quantities of phenolics such as quercetin (up to 17.95 mg g-1), naringin (up to 5.07 mg g-1) and luteolin-7-O-glucoside (up to 3.54 mg g-1). Overall, this comprehensive concept highlights the ability of these Lamiaceae species to safeguard the DNA from reactive oxygen species, to curtail the inflicted damage and also improve the efficiency of the DNA repair mechanisms, while emphasizing the importance of polyphenols as their active principles.

AB  - Salvia officinalis (sage) and Salvia rosmarinus (previously Rosmarinus officinalis, rosemary) are commonly used medicinal plants from the Lamiaceae family, with strong antioxidant abilities. This study was carried out in several stages to comprehensively and gradually explore the antioxidant and antitumor mechanisms of their ethanolic extracts using different experimental approaches. Their in vitro antioxidant activity was assessed using ABTS assay. Plasmid pUC19 E. coli XL1-Blue was used to evaluate their genoprotective activity, while SOS/umuC assay on Salmonella typhimurium TA1535/pSK1002 and Comet assay on human lung fibroblast cell line (MRC-5) were employed to examine their antigenotoxic potential. Furthermore, their antitumor mechanisms were analyzed on the colorectal cancer cell line (HCT-116) by testing their impact on the cells’ viability (MTT assay), as well as the production of reactive oxygen species (ROS) (NBT test) and nitric oxide (NO) (Griess assay). The results showed that sage extract had slightly higher ABTS-scavenging and antigenotoxic activities in the bacterial model when compared to the rosemary extract, however, opposite results were obtained for the acellular model. Moreover, both extracts protected the MRC-5 cells from the induced genomic damages. As for tumor cells, sage extract reduced their viability by approximately 10 %. Additionally, both extracts significantly reduced the ROS production, while also increasing the NO production, especially the rosemary extract. These results delivered novel information about the nature of antioxidant effects of sage and rosemary ethanolic extracts. They provided substantial protection of the acellular, bacterial and healthy human cellular models by employing radical-scavenging and antigenotoxic mechanisms. At the same time, both extracts exhibited antitumor activity towards colorectal cancer cells in vitro that could be mediated by inducing an increase in NO production. With that being said, sage and rosemary ethanolic extracts represent potent genoprotective, antioxidant and antitumor agents. However, their exact mechanisms of action remain to be further explored and clarified

AB  - The main objective of this research was to evaluate the impact of methanolic, ethanolic and aqueous extracts of Origanum majorana L., Origanum vulgare L., Teucrium chamaedrys L., Teucrium montanum L., Thymus serpyllum L. and Thymus vulgaris L. (Lamiaceae) on the effects of free radicals using different model systems. The extracts were characterized on the basis of the contents of total phenolics, phenolic acids, flavonoids and flavonols, and also using high-performance liquid chromatography with diode-array detection. Antioxidant activity in vitro was assessed using DPPH assay. The genoprotective properties were tested using plasmid relaxation assay on pUC19 E. coli XL1-Blue, while SOS/umuC assay on Salmonella typhimurium TA1535/pSK1002 and Comet assay on human lung fibroblasts were used to assess the antigenotoxicity of the extracts. Ethanolic extracts had the most phenolics (up to 236.20 mg GAE/g at 0.5 mg/mL), flavonoids (up to 42.47 mg QE/g at 0.5 mg/mL) and flavonols (up to 16.56 mg QE/g at 0.5 mg/mL), and they exhibited the highest DPPH activity (up to 92.16% at 0.25 mg/mL). Interestingly enough, aqueous extracts provided the best protection of plasmid DNA (the lowest IC50 value was 0.17 mg/mL). Methanolic extracts, on the other hand, most efficiently protected the prokaryotic DNA, while all the extracts had a significant impact against genomic damages inflicted on human fibroblasts. O. vulgare extracts are considered to be the most promising in preserving the overall DNA integrity against oxidative genomic damages. Moreover, HPLC-DAD analysis highlighted rosmarinic acid as the most abundant in the investigated samples (551.45 mg/mL in total in all the extracts), followed by luteolin-7-O-glucoside (150.19 mg/mL in total), while their presence correlates with most of the displayed activities. The novelty of this study is reflected in the application of a prokaryotic model for testing the antigenotoxic effects of Lamiaceae species, as no previous reports have yet been published on the genoprotective potential of these species.

AB  - Recently, there has been an increasing interest in the chemistry and biological potential of mosses, since a large number of biologically active compounds have been found within these species. This study aimed at examining the chemical composition and immunomodulatory potential (antioxidant, antidiabetic, anti-neuroinflammatory/antineurodegenerative, and antitumor activities) of moss Hypnum cupressiforme Hedw. extracts. Corresponding extracts have been obtained applying Soxhlet extractor. The chemical characterization was performed using spectrophotometric assays and liquid chromatography-mass spectrometry (LC-MS). The extracts were analyzed for antioxidant activity and for inhibitory activities on α-glucosidase, α-amylase, acetylcholinesterase, and tyrosinase. Additionally, extracts were tested against four cell lines-MRC-5, BV2, HCT-116, and MDA-MB-231-for antitumor and anti-inflammatory activities. Chemical analysis of extracts revealed the presence of flavonoids, phenolic acids, and triterpenoids. Major compounds identified by LC-MS in H. cupressiforme were kaempferol and five phenolic acids: p-hydroxybenzoic, protocatechuic, p-coumaric, gallic, and caffeic acid. According to biochemical assays the investigated extracts exhibited significant immunomodulatory potential. Significant antiproliferative potential against MDA-MB-231 cells has been observed together with the promising anti-neuroinflammatory application. The obtained data suggest that moss H. cupressiforme is a valuable natural source of biologically active compounds with potential application in the pharmaceutical industry.

AB  - Mosses have recently been recognized as promising sources of novel biologically active compounds applicable in the prevention of numerous pathological conditions or as potent adjuvant therapeutics. This study aimed to examine the chemical composition and immunomodulatory potential (antioxidant, antidiabetic, anti-neuroinflammatory, antineurodegenerative, and antitumor activities) of the moss H. cupressiforme extracts. The corresponding extracts were obtained using solvents of different polarities and their mixtures with Soxhlet extractor and further characterized by spectrophotometric assays and liquid chromatography coupled to mass spectrometry (LC-MS). The antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), total reduction power, and β-carotene bleaching assays. Further on, the inhibitory activity on α-glucosidase, α-amylase, acetylcholinesterase, and tyrosinase was tested. Additionally, biocompatibility, antitumor, and anti-inflammatory potential were tested on MRC-5, HCT-116, MDA-MB-231, and BV2 cells, respectively.

Chemical analysis of the moss extracts revealed the presence of flavonoids, phenolic acids, and triterpenoids. The major compounds identified by LC-MS in H. cupressiforme extracts were kaempferol and five phenolic acids: p-hydroxybenzoic, protocatechuic, p-coumaric, gallic, and caffeic acid. Biochemical assays revealed the significant immunomodulatory potential of examined extracts. Moreover, significant antiproliferative potential against human breast cancer cells – MDA-MB-231, with the proliferation inhibition rate up to 50%, and acceptable biocompatibility was observed. Also, a significant decrease in NO production, observed in lipopolysaccharide-stimulated BV2 cells, implies potential anti-neuroinflammatory application. Overall, obtained results qualify the moss H. cupressiforme as a highly promising candidate for more detailed examination and also putative therapeutical application.

abstract = "Mosses have recently been recognized as promising sources of novel biologically active compounds applicable in the prevention of numerous pathological conditions or as potent adjuvant therapeutics. This study aimed to examine the chemical composition and immunomodulatory potential (antioxidant, antidiabetic, anti-neuroinflammatory, antineurodegenerative, and antitumor activities) of the moss H. cupressiforme extracts. The corresponding extracts were obtained using solvents of different polarities and their mixtures with Soxhlet extractor and further characterized by spectrophotometric assays and liquid chromatography coupled to mass spectrometry (LC-MS). The antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), total reduction power, and β-carotene bleaching assays. Further on, the inhibitory activity on α-glucosidase, α-amylase, acetylcholinesterase, and tyrosinase was tested. Additionally, biocompatibility, antitumor, and anti-inflammatory potential were tested on MRC-5, HCT-116, MDA-MB-231, and BV2 cells, respectively.

Chemical analysis of the moss extracts revealed the presence of flavonoids, phenolic acids, and triterpenoids. The major compounds identified by LC-MS in H. cupressiforme extracts were kaempferol and five phenolic acids: p-hydroxybenzoic, protocatechuic, p-coumaric, gallic, and caffeic acid. Biochemical assays revealed the significant immunomodulatory potential of examined extracts.

AB  - Owing to structural diversity and potental pharmacological activity, bioactive compounds derived from natural sources are in the focus of intensive exploration. In this study, the chemical composition of different moss extracts of Hedwigia ciliata P. Beauv. was examined, and further tested for antioxidant, antineurodegenerative/anti-neuroinflammatory, antidiabetic, and antiproliferative activity in vitro. The extracts were prepared by Soxhlet extractor using solvents of different polarity. Chemical analysis revealed the presence of phenolics, flavonoids, and triterpenoids as secondary metabolites of high biological activity. Antioxidant activity of extracts was assessed using three different methods, DPPH (2,2-diphenyl-1-picrylhydrazyl), total reducing power assay, and β-carotene/linoleic acid assay. To evaluate the enzyme-inhibitory activity, extracts were screened for α-amylase, α-glucosidase, acetylcholinesterase, and tyrosinase inhibitory effects. The biocompatibility of moss extracts was confirmed using normal human fibroblast cell line, MRC-5. The H. ciliata extracts displayed significant antiproliferative activity (~ 50% inhibition) against the MDA-MB-231 (human breast adenocarcinoma) cells, which had not previously been reported elsewhere. The potential anti-neuroinflammatory activity was observed due to significant reduction of the NO production by LPS-stimulated BV2 (normal murine microglia cell line), being in line with previously recognized antineurodegenerative potential, as measured by the inhibition of acetylcholinesterase and tyrosinase activity. Furthermore, the H. ciliata extracts displayed significant antidiabetic effect via α-glucosidase inhibition. In general, the obtained results suggest the potential immunomodulatory activity of the moss H. ciliata extracts, remaining to be characterized in more detail in search for mechanisms underlying the immunomodulation processes.

AB  - The physiological imbalance between the production and accumulation of reactive oxygen species (ROS), known as oxidative stress, is responsible for developing and progression of a plethora of diseases – cancer, among others. Since plants are recognized as potential antioxidant agents, the aim of this study was to chemically characterize ethanolic extracts of 18 species from Lamiaceae family using liquid chromatography-mass spectrometry (LC-MS), followed by testing the antioxidant activity using ABTS assay. Biocompatibility of the investigated extracts was assessed by MTT assay on normal human lung fibroblasts (MRC-5). Finally, antiproliferative activity was evaluated using MTT assay on human colorectal cancer (HCT-116) cell line, while the effects of extracts on superoxide anion radical (O2•-) production were tested using NBT assay. Melissa officinalis, Mentha piperita, Origanum majorana, O. vulgare, and Thymus vulgaris showed the highest antioxidant activity against ABTS radicals. LC-MS analysis indicated that these extracts mostly contain caffeic, protocatechuic and p-coumaric acids. The extracts were biocompatible with MRC-5 cell line. Interestingly, Lavandula angustifolia and Ocimum basilicum extracts, which were less active against ABTS radicals, showed a significant antiproliferative effect against HCT-116. Moreover, L. angustifolia and T. vulgaris extracts significantly stimulated the production of O2•- in HCT-116, indicating potential antitumor activity. The extracts that expressed antiproliferative effect and stimulated ROS production contain higher amounts of rosmarinic, caffeic and chlorogenic acids, naringin, luteolin, apigenin and cirsimaritin, indicating that some of them, or more probably their synergistic effects, are responsible for the extracts’ ability to moderate the production of ROS in HCT-116 cells.
