    Abstract: The effect of growth stage on the physicochemical composition and antioxydant activities of olive leaves extracted with solvents of increasing polarity was investigated at two different stages. The total phenolic, total o-diphenols and total flavonoid were measured. Therefore, the levels of chlorophyll and carotenoids were also measured. The conten... Show More

    Abstract: The antioxidant capacity and phenol content of the olive fruits from the variety chetoui, were studied. Four solvent systems were used; hexane, dichloromethane, ethyl acetate and methanol. The antioxidant capacity of the fruit extracts was evaluated using 2,2-diphenyl-1-picrylhydrazyl radical-scavenging assays. The efficiency of the solvents used t... Show More
