Abstract

The alcoholic extract of the plants Azadiracta indica, Argimone maxicana, Malvastrum tricuspidatum and Allium sativum were investigated for their free radical scavenging activity by DPPH and Nitric oxide scavenging method. Ethanolic extract of A. indica, and M. tricuspidatum, A.sativum and A. maxicana showed remarkable free radical scavenging activity. It interacted significantly with free radical DPPH at concentration of 8, 16, 32, 64, 125, 250, 500 and 1000mg/ml. The IC50 value was 63.71, 82.16, 64.62 and 73.6 mg/ml respectively as compared to 93.53 mg/ml of standard ascorbic acid. In nitric oxide scavenging method is at all concentration of 8, 16, 32, 64, 125, 250, 500 and 1000mg/ml. The IC50 value was 67.87, 74.35, 61.24 and 74.26 mg/ml respectively. All the extracts showed significant free radical scavenging activity with mild variation.
