Abstract
The compound, α-(2-hydroxy-2-methylpropyl)-ω-(2-hydroxy-3-methylbut-2-en-1-yl)polymethylene, isolated from ethyl acetate leaf extract of Caesalpinia bonducella (L.) Flem. was evaluated for antimicrobial activity against clinical isolates, Proteus vulgaris, Pseudomonas aeruginosa, Klebsiella sp., Staphylococcus citrus, Staphylococcus aureus, Escherichia coli, Candida albicans and Rhodotorula sp. using agar diffusion method. The compound exerted inhibitory zone at all concentrations and revealed the concentration-dependent activity against all tested bacterial and yeast strains comparable to standards streptomycin sulphate and gentamycin for bacteria and fluconazole and griseofulvin for Candida albicans and Rhodotorula sp. The inhibition zones were wider and clear for C. albicans and Rhodotorula sp. (IZ >20 mm) and for Pseudomonas aeruginosa, P. vulgaris and E. coli zones were greater than standards tested, whereas, zones for Klebsiella sp. and S. aureus were similar to standards.
Highlights
