| Description |
The present study was designed to explore the antioxidant potential of chloroform, ethyl acetate, n-butanol and water fractions of
80% methanol extract of leaves Chukrasia tabularis by 2,20-diphenyl-1-picrylhydrazyl (DPPH), deoxyribose degradation (non-site specific
and site specific), reducing power and DNA nicking assays. The different fractions showed significant activities in all the free radical scavenging
tests and these findings have also shown direct relationship between antioxidant activity and phenolic content. Among the fractions,
ethyl acetate fraction exhibited highest inhibition of 93.14%, 89.99%, 87.04% in DPPH, non-site specific and site specific
deoxyribose degradation assays, respectively and 91.20% reduction of ferricyanide to give Prussian blue coloured complex in reducing
power assay at maximum concentration tested. This preliminary study indicates the antioxidant activity of the leaves of Chukrasia tabularis,
and moreover the results showed correlation with the amount of phenolic content present in different fractions.
