| Abstract: | The free radical scavenging potential of the
plant S.indicus was studied by using
different antioxidant models of screening. The ethanolic extract at 1000  g/ml showed maximum scavenging of the radical cation, 2,2-azinobis-(3-ethylbenzothiazoline-6-sulphonate)
(ABTS) observed upto 41.99 % followed by the scavenging of the stable radical
1,1-diphenyl, 2-picryl hydrazyl (DPPH) (33.27 %), superoxide dismutase (25.14
%) and nitric oxide radical (22.36 %) at the same concentration. However, the
extract showed only moderate scavenging activity of iron chelation (14.2 %).
Total antioxidant capacity of the extract was found to be 160.85 nmol/g
ascorbic acid. The results justify the therapeutic applications of the plant in
the indigenous system of medicine, augmenting its therapeutic value. |
