Abstract :
[en] The purpose of the present study was to evaluate the composition of fatty acids, antioxidant and phenolic compounds in Acacia polycantha and Azadirachta indica seed extracts for their potential uses in nutrition. Extractions of oil using several techniques (Sohxlet, ultrasound and microwave) in several solvents were carried out and the oils were characterised. Total phenolic content ranged between 4.22 and 31.48 mg GAE/g. Antioxidant activity (CE50) ranged between 1.95 and 22.91 mg/mL. Oleic and linoleic acids were the major unsaturated fatty acids while palmitic and stearic acids were the major saturated fatty acids in both oils. 3‐hydrobenzoic acid, resveratrol rutin, and flavan were identified by HPLC‐DAD at high contents while chlorogenic acid, vanillic acid, syringic acid, epicatechin, p‐coumaric acid, transferulic acid, ellagic acid, rutin, cinnamic acid, chlorogenic acid, caffeic acid were lower in Neem oil. In case of A. polycantha oil, the percentages of ellagic acid and rutin were high.
