Abstract

The present study was to investigate the antioxidant activity of methanolic extract of leaves and rhizomes of Acorus calamus L by using DPPH (2, 2 diphenyl-1-picrylhydrazyl). Both the extracts exhibit potential free radical scavenging activity. The rhizome extract displayed stronger 2, 2 diphenyl-1-picrylhydrazyl free radical scavenging activity comparing to leaves extract. Free radical scavenging activities of methanolic extract of leaf and rhizome of A. calamus showed the scavenging property of 68% and 95% respectively. Total phenolic content in each extracts were also determined. Total phenolic content was found to be 17.1±0.04 and 17.3±0.88 mg gallic acid/g of extract respectively. The study revealed the correlation between the total phenolic content and antioxidant activitiy to free radical scavenging property of extracts of leaves and rhizomes of A. calamus
