The antioxidant activity of the plant extracts and the standards were assessed on the basis of
the radical scavenging effect of the stable DPPH-free radical [2] and nitric oxide radical
inhibition assay by modified Griess Ilosvay reaction.[2] The crude methanolic extract was
found to be the most potent, hence, it was screened for in vitro antioxidant activity using
scavenging of various radicals like ABTS radical cation,[3] hydroxyl radical (by bleaching of
p-NDA method [4] and deoxyribose method [5]), superoxide radical (by alkaline DMSO …
