Evaluation of Antioxidant Activity of Aerial Parts of Hygrophila difformis

Abstract

The in vitro antioxidant activity of aerial parts of Hygrophilla difformis has been investigated by estimating degree of non-enzymatic haemoglobin glycosylation measured colorimetrically at 520 nm. The benzene and chloroform extract of aerial parts of H. difformis showed higher antioxidant activity than other extracts of it. The antioxidant activity of the extracts is close and comparable to that of the standard antioxidant compounds used.
