Open Access Toplam 120 atıf DOI
This study was focused on the analysis of the phenolic content, antioxidant, antibacterial, anti-cholinesterase, anti-tyrosinase, anti-amylase and anti-glucosidase activity of three solvent extracts from Cotoneaster nummularia. Moreover, water extract was tested in terms of mutagenic/anti-mutagenic effects. The antioxidant activities of these extracts were evaluated by DPPH, ABTS, O2, metal chelating, phosphomolybdenum, b-carotene/linoleic acid, ferric and cupric reducing power assays. Enzyme inhibitory activities were also examined with colorimetric methods. Generally, methanol and water extracts exhibited excellent biological activities. These extracts were rich in phenolic and flavonoid content. Furthermore, Cotoneaster extracts indicated appreciable antibacterial properties against human pathogen strains. HPLC analysis showed that ferulic acid, chlorogenic acid, (-)-epicatechin and (+)-catechin were the major phenolics in extracts tested. These data offer that these extracts from C. nummularia may be considered as a potential source of biological agents for developing functional foods or drug formulations. Copyright:

Morina persica L. has weak rosy smell flowers that together with aerial parts are infused or decocted and used as a functional tea. It is a representative of the Anatolian traditional medicine and is used for the treatment of cold. Biological and chemical fingerprints of different extracts (methanolic, acetone and water) of M. persica were investigated. Antioxidant, enzyme inhibitory, antimicrobial, cytotoxic and mutagenic/antimutagenic effects were evaluated for biological profiling. Rutin, chlorogenic and rosmarinic acids were detected as dominant compounds. Generally, the methanolic and acetone extracts had strong antioxidant, enzyme inhibitory, antimicrobial and antimutagenic effects. Additionally, all extracts showed remarkable inhibitory effects on HeLa cells at 100 μg/mL. Furthermore, possible interactions between rutin, the dominant phenolic compound in M. persica and the tested enzymes were assessed by molecular docking. Results indicate that M. persica could be considered as a natural source of high-valued functional ingredients for further use in healthful formulations.
