Plant-derived substances have been used since antiquity for therapeutic and other purposes. The present study was undertaken to make a comparative analysis of antimicrobial and antioxidant properties of 8 medicinal plants, which are used in traditional medicine system. Methanolic extracts of Centella asiatica (leaves), Mentha piperita (leaves), Calotropis gigantean (leaves), Vitex nigundo (leaves), Bauhinia racemosus (leaves), Emblica officinalis (fruit), Bauhinia purpurea (leaves), Asperagus racemosus (stem) were tested for anti-microbial effects using the standard Agar Diffusion method. Antioxidant attributes of above extracts were studied by testing their ability to scavenge DPPH and ABTS radicles. Our results indicated that all tested extracts, with the exception of Bauhinia purpurea, were effective against E. Coli, while Candida albicans was only sensitive to Asperagus racemosus. Among tested extracts, Bauhinia racemosus was most potent in exhibiting radical scavenging activity. Our data provides rationale for exploitation of these plants for antimicrobial and antioxidant attributes.
