Evaluation of Phytochemical Composition and Antioxidant Potency of Two Algerian Cultivars of Olea Europaea Leaves

In Mediterranean countries, Olea europaea L. is among the most important fruit trees widely cultivated. This plant has a wide range of biological activities that have increased their interest in the medical and health fields. The aim of this study was to quantify total phenols and flavonoids compounds and evaluate the antioxidant potential of two Algerian cultivars olive leaves ( Sigoise and Chemlal). The two olive leaves exhibited meaningful phenolic and flavonoids content with superiority for Chemlal extract ; the contents are respectively 238,32 mg GAE/g and 79,37 mg QE/g. the antiradical effect toward DPPH and B-carotene assays showed that Chemlal cultivar is the most active, with 82,33% and 72%, respectively. These findings provide evidence that Olea europea bark and roots are potential sources of antioxidant which have many benefits towards human health.
