The present investigation has been carried out to evaluate the in vitro antioxidant and antimicrobial activity. The in vitro antioxidant activity of leaves of Boerhaavia diffusa was investigated by Fe-EDTA method. In this method plant extract (leaves) possess high antioxidant activity when compared with standard ascorbic acid and the antimicrobial activity was visually recorded by measuring zone of inhibition in millimeters. The zone of inhibition varied by plant extract with different concentration. The largest zone of inhibition (19 mm) was found against E. coli using ethanolic extract of leaves of Boerhaavia diffusa. The result obtained indicates that the ethanolic extract of Boerhaavia diffusa showed high antioxidant and antimicrobial activity.
