Evaluation of antioxidant activity of flower and seed oil of Azadirachta indica A. juss
Article Main
Abstract
The present study on evaluation of antioxidant activity of the flowers and seed oil of Neem plant Azardirachta indica A. Juss revealed that the ethanolic extract of flowers and seed oil at 200 ?g/ml producing the highest free radical scavenging activity i.e. 64.17±0.02% and 66.34±0.06% respectively. The Neem oil has the highest amount of total phenol content (132 ?g/ml) which is responsible for highest percentage of inhibition of DPPH radical. In conclusion Neem flower and seed oil have potential for use in human health which is used as food by common people and in diabetes and Neem seed oil is widely used for variety of diseases and also antioxidant potential for use in different pharmaceutical industries.
