The aqueous and ethanol extracts of leaves of the Ichnocarpus frutescens were screened for their antimicrobial activity by well-in-agar method. The extracts were tested against bacteria like Bacillus subtilis, staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Vibrio cholerae and fungi like Saccharomyces cervisiae, Cryptococcous neoformonas, Candida albicans (unicellular fungi), Aspergillus niger and Fusarium sps (multicellular fungi). The susceptibility of the microorganisms to the extracts of the leaves of plant was compared with selected standard antibiotics (Chloramhenicol and fluconozol). The water extracts gives the inhibition zone of 10 mm on Fusarium sps (fungi). For Vibrio choerae, the water extract gives the inhibition zone of 11 mm. The rest of organisms tested were resistant to both extracts.
