The present study was undertaken to explore the free radical scavenging, antimicrobial and cytotoxic activity of the methanolic extract of Glycyrrhiza glabra (Fabaceae) using DPPH, disc diffusion and brine shrimp lethality bioassay methods respectively. Different degrees of effect was noticed incase of different methods of study. In antimicrobial screening, G. glabra showed potent antimicrobial activity against almost all the test organisms except Pseudomonas aeruginosa. It exhibited highest
