摘要：Pistacia lentiscus seed oil is a natural product widely used for culinary and medicinal purposes in Algerian and Tunisian forest areas. Until now, the quality of this oil is still not well known. This study aims to optimize its quality b y determin ing the best period to harvest fruits. Quality criteria include fatty acid composition and antioxidant activity of this oil. Fruits were harvested during three maturity stages: unripe, ripe and over ripe. Oleic acid was the major fatty acid (more than 40%), followed by palmitic (22.28-28.6%) and linoleic (13.63-20.5%) acids. Antioxidant activity was estimated using DPPH scavenging ability and Trolox Equivalent Antioxidant Capacity (TEAC) assays. Oil extracted from the pulp at over- ripeness showed the highest percentage of inhibition of DPPH with about 37% corresponding to 80 ng of Trolox/g of oil.
