Abstract

Over the past decade, there has been a growing interest in research focused on extracting biologically active compounds from natural sources as Olea europaea L. The objective of the current study was to explore the content of some antioxidants extracted from olive leaves of nine Algerian cultivars. Subsequently, the antioxidant activities of these compounds extracts were assessed.

The antioxidant properties were determined through total antioxidant capacity (TAC), DPPH, and reducing power assays. The results indicated that ethanolic extracts of all studied cultivars are rich in total antioxidant compounds. Abani extract exhibited the highest TAC (499.70 ± 15.93 mg AAE/g DW), the highest reducing power (A0.5 = 11.03 ± 1.47 μg /ml) and was the most effective against the DPPH free radical (IC50 = 46.67 ± 1.58 μg /ml). Furthermore, the study revealed that the cultivar factor significantly influenced the antioxidant properties. The results obtained in the present study indicate that ethanolic extract of Algerian olive leaves constitute a potential source of natural antioxidants, and support the traditional use of this plant in the treatment of infectious diseases.
