Potential aptitude of four olive cultivars as anticancer and antioxidant agents: oleuropein content

Abstract Olea europaea L. (olive, Oleaceae) constitutes a source of many bioactive compounds, which have recognized benefits for both human health and technological purposes. The present article was carried out to evaluate the biological activity oleuropein (an ester 2-(3,4-dihydroxyphenyl) ethanol (hydroxytyrosol) has oleosidic skeleton that is common secoiridoid glucosides Oleaceae). It occurred in leaf extracts four olive cultivars (Chemlali, Manzanilla, Picaul Toffahi) as some anticancer antioxidant agents their consequences on action Hordeum vulgare (barley). total phenolic flavonoid compounds were extracted from leaves by 95% then analyzed high-performance liquid chromatography (HPLC). study evaluates ethanolic extract against breast hepatocellular carcinoma cells showing high values. Also, exhibited highly consequence potentiality barley assessed using diphenyl picryl hydrazyl method (DDPH). These results pave way utilization natural agents.
