Unripe Fruits of Pistacia Terebinthus from Algeria: Fatty Acid Composition, Tocopherols, Sterols, Carotenoids, Phenolic Compounds, and Free Radical Scavenging Activity

Abstract

This study aimed to determine the lipid and phenolic compound content of immature Pistaciaterebinthusfruits and their anti-radical activity. The results show that red fruits have a low lipid yield (0.98 and 2%), rich in tocopherols, sterols, and carotenoids. The proportion of unsaturated fatty acids is higher (65.19 to 77.30%) than saturated fatty acids in all lipid classes except glycolipids and phospholipids. Immature fruit cakes are high in total phenols (4.05 and 271.58 mg EAG/g cake), low in tannins (0.50 to 3.40 mg ECAT /g cake), and lacking in flavonoid compounds. The antioxidant activity of total lipids, neutral lipids, and phenolic extracts from immature fruit is high (1.50, 1.076 mg EVE/g lipid and 43.17μg EVC/g oilcake), respectively.
