Evaluation of the Antioxidant activity of the roots and Rhizomes of<i>Cyperus rotundus</i>L.

Abstract

The in vitro antioxidant activity of the roots and rhizomes of Cyperus rotundus L. has been investigated by estimating degree of non-enzymatic haemoglobin glycosylation, measured colorimetrically at 520 nm. The ethanol extract of the roots and rhizomes of C. rotundus showed higher activity, than other extracts of it. The antioxidant activity of the extracts are close and identical in magnitude, and comparable to that of standard antioxidant compounds used.
