摘要

The current study aims at investigating the chemical composition of fatty acids and the quantification of sterols, tocopherols, and carotenoids in Phillyrea angustifolia (Oleaceae) fruits that grow in Algeria, as well as evaluating the antioxidant activity of dewaxed lipids. The latter’s composition within the studied samples is made up of the fatty acids that are usually found in olive fruits. P. angustifolia fruits are rich in unsaturated fatty acids with a total percentage of around 90%, represented mainly by Oleic acid (62.06–75.11%) and linoleic acid (13.00- 21.66%). Saturated fatty acids are also present in the taken samples, mainly palmitic and stearic, detected in considerable amounts. Additionally, the quantification of total sterols content and total tocopherols Content reveals that p. angustifolia’s fruit oil is rich in sterols and tocopherols with the amounts of 28.76–55.90 mg/g lipid and 5.02–10.14 mg/g lipid, respectively; also, total carotenoids content shows a lower amount (0.31–1.04 mg/g lipid). Finally, the antioxidant activities (DPPH, FRAP) demonstrate that dewaxed lipids in fruits manifest a good antioxidant activity. According to the obtained results. It must also be noted that this phytochemical study of fruits was conducted for the first time.
