Abstract

The present study includes evaluation of the antimicrobial activity of methanolic extracts of some plant parts of Indian origin against two gram-positive and two gram-negative bacterial strains with reference to B. subtilis, S. aureus, P. Aeruginosa, E. coli using the disk diffusion method. The methanolic plant extracts used in present study are derived from pomegranate peel, lemon peel, wheatgrass, curcuma longa leaves, sheesham leaves and papaya leaves. A systematic concentration variation method was used to evaluate antimicrobial potential of these plant extracts. Results showed that pomegranate peel extract, lemon peel extract, curcuma longa leaves extract and wheatgrass extract have higher antimicrobial activity, whereas sheesham leaves extract and papaya leaves extract have lower antimicrobial activity.
