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:

In the present study, the methanolic extracts of Cytisopsis dorycniifolia and Ebenus hirsuta were analyzed for antioxidant, enzyme inhibitory, antimicrobial and antigenotoxic activities. The identification and quantification of phenolic compounds in these extracts were performed using liquid chromatography coupled with mass spectrometry (LC-MS/MS) technique, and the main components were hyperoside, rutin, hesperidin, tannic acid and p-coumaric acid. The extracts had remarkable biological effects. Generally, C. dorycniifolia had higher level of bioactive components and exhibited stronger in vitro antioxidant effects than E. hirsuta. E. hirsuta was active especially against bacteria Pseudomonas fluorescens and Agrobacterium tumefaciens and fungi Puncturella fastigiata, while C. dorycniifolia was active against bacteria E. faecalis and had moderate activity against Trichoderma species. The extracts displayed strong antigenotoxic effects (98.6% for E. hirsuta and 76.3% for C. dorycniifolia). Our findings suggested that C. dorycniifolia and E. hirsuta could be beneficial for the preparation of high-value pharmaceuticals and functional food ingredients.
