Abstract

Shade dried neem (Azadirachta indica) flower powder (NFP) was evaluated for composition, fatty acid profile, volatile oil composition and antioxidant activity. NFP was rich in protein (17.34%), fiber (12.32%) and ash (9.16%). The volatile oil (0.07%) contained 85% of caryophyllene. The lipid yield of NFP was 12%, which was composed of equal quantities (45 ± 1%) of saturated (SFA) and poly unsaturated fatty acids (PUFA). In SFA, the palmitic (31.76%) was major, in PUFA, linoleic (18.57%), linolenic (12.64%) and oleic (9.74%) were higher. Arachidonic (20:4) and docosatrienoic acids (22:3) were also present to an extent of 7.38% and 5.7%, respectively in the total lipid. NFP showed 25.31% radical inhibition with 0.6 mg and 58.50% at 2 mg and comparable iron reducing power. The results reveal that neem flower volatile fraction and lipid can be further explored for pharmaceutical or food applications.
