Survey of phytochemical composition and biological effects of three extracts from a wild plant (Cotoneaster nummularia Fisch. et Mey.): A potential source for functional food ingredients and drug formulations
Scopus
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:

Capparis spinosa L. (caper), is a traditionally used medicinal plant and widely studied for its biological properties. We aimed for the first time to compare the biological and phenolic fingerprints of C. spinosa buds, collected from Morocco, Turkey, and Italy. Phenolic compounds, fatty acids, and essential oils were profiled by chromatographic techniques. Enzymes inhibitory activities of different extracts were tested by spectrophotometric methods. Antioxidant capacity was evaluated by different assays including free radical scavenging, reducing power, metal chelating and phosphomolybdenum. Moroccan sample showed the highest phenolic content across all extraction types followed by Italian and Turkish. Rutin was detected as main compounds in the extracts and the Italian decoction extract had highest rutin content. Moroccan samples exhibited the highest activity in microwave and Soxhlet extracts. The highest acetylcholinesterase inhibitory activity was observed in Turkish Soxhlet and Moroccan samples. The best butyrylcholinesterase inhibitory effects were also detected in the Italian extracts. The predominant fatty acid was α-linoleic acid (C 18:3 ω3; 28.65%), observed from Turkish sample. n-Hexadecanoic acid was the main component in the essential oils (13.9%, 25.03%, and 36.67% for Italian, Turkish, and Moroccan samples, respectively). Our results strongly advocate that future formulation of C. spinosa as active ingredient should also take into account the geographical origins and extraction techniques.
