Olive leaves (OLL), an agricultural waste by-product, are considered a significant bioresource of polyphenols, known as bioactive compounds. This study evaluates the pulsed electric field (PEF) technique for extraction polyphenols from OLL. The parameters included series “green” solvents (ethanol, water well mixtures them at 25% step gradient) and different input values pulse duration PEF. phyt...

The current work aimed to determine the effects of antioxidant and physicochemical properties sumac fruits on its antimicrobial activity. Samples collected from Mardin Diyarbakır provinces which are located in Turkey’s Southeastern Anatolia were used results compared among each other. taken analysed separately, they exhibited high activities. Analyzes performed aqueous extracts samples. highest...

pomegranate tree possesses a vast ethnomedical history and represents a phytochemical reservoir of heuristic medicinal value. in the present study, total phenolics, antioxidant, and antibacterial activities of pomegranate peel were determined by folin–ciocalteu, 2,2-diphenyl-1-picrylhydrazyl (dpph) and disk-diffusion methods, respectively, and compared among the accessions. methanolic extract g...

the antioxidant activities of methanol (me), ethanol (ee), water (we) and ethyl acetate (eae) extracts of four inula helenium l. taxa (i. helenium ssp. orygalis (boiss.) grierson, i. helenium ssp. pseudohelenium grierson, i. helenium ssp. turcarasemosa grierson and i. helenium ssp. vanensis grierson) were investigated. the phosphomolybdenum assay, β-carotene–linoleate bleaching and dpph radical...

Plants are valuable sources of antioxidants, which could have beneficial effect on human health. In this respect flavonoids and other polyphenolic compounds gained the greatest attention. The present study was undertaken to evaluate in vitro antiradical activity different extracts (ethanol, hexane, acetone, chlorophorm methanol) Artemisia vulgaris L., A. fragrans Willd., absinthium L. splendens...
