In the present investigation antioxidant and alphaamylase inhibitory activity of chloroform fraction of Argemone mexicana were evaluated. The antioxidant activity of chloroform fraction of A. mexicana was evaluated by DPPH, Super oxide radical Scavenging activity, ABTS radical cation scavenging activity and Nitric oxide radical scavenging activity. Alpha-amylase inhibitory activity of chloroform fraction was evaluated by DNS method respectively. The observed resultant antioxidant activity of chloroform fraction in all studied models was moderate as compared with reference standard Ascorbic acid. The chloroform fraction exhibited appreciable α-amylase inhibitory activity with an IC50 value 48.92μg/ml respectively, when compared with acarbose (IC50 value 83.33μg/ml).In conclusion, from the results of present study it is confirmed that antioxidant and alpha-amylase inhibitory activity of chloroform fraction of A. mexicana may contribute in its earlier observed antidiabetic potential.
