STUDIES ON ANTIMICROBIAL POTENTIAL OF BAUHINIA VAHLII STEM EXTRACTS
The antimicrobial potential of ethanolic extract (EE) and aqueous extract (AE) of stem of Bauhinia vahlii were evaluated in vitro against some specific bacterial and fungal species employing well diffusion method and serial dilution methods. The patterns of inhibition varied with the stem of Bauhinia vahlii extracts, the solvent used for extraction and the organisms tested. The strains used included Staphylcoccus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, (reference strain) and two fungal strains including (Candida albican and Aspergillus niger) were used for antimicrobial activity assessment. The EE of stem showed a relatively potent antimicrobial activity than the AE. Further studies are to be carried out to find out the chemical composition of the plant extracts.
