Phytochemicals content and in-vitro antioxidant properties of Azadirachta indica seeds, leaves and twigs prepared from different extraction techniques

The current study was design to exploit the Azadirachta indica leaves, seeds and twigs for %yield, phytochemicals content antioxidant activities using infusion, hydroalcoholic, decoction microwave extraction techniques. contents were determined by standard reported methods. While activity assessed three (03) standards In-vitro test systems as 1, 1’-diphynyl- 2-picrylhydrazyl (DPPH), Hydrogen peroxide (H2O2) scavenging Nitric oxide (NO) method ascorbic acid standard. highest extractive yield observed in seed 44.00±02% (infusion), 38.00±00% (Hydroalcoholic) 20.00±03% (decoction). Followed leaves parts of neem. high amount (+++) extracted from neem infusion hydroalcoholic extracts compared with (neem) extract showed at 1000 mg/L remarkably inhibited DPPH inhibition (85±01), H2O2 (83±01%), NO (78±01%). antioxidants a dose dependant manner, higher concentration activities. results pointed significant techniques, overall strength being order >hydroalcoholic >decoction >microwave extracts. In all cases, obtained than other technique twigs. indicate that have potent would beneficial effects on human health are superior better potential.
