Antimicrobial Evaluation of Kigelia africana (Lam)

R. Jeyachandran and A. Mahesh    

Abstract: The evaluation of the activity of the aqueous, methanol and chloroform extracts of the bark of the Kigelia africana (Lam) was tested against E. coli, Enterobacter aerogens, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, Pseudomonas aeruginosa (Gram-negative), Staphylococcus aureus and Bacillus cereus (Gram-positive) by disc diffusion method. The methanol extracts presented a higher activity than the aqueous and chloroform extracts. It exhibits the greatest activity against Salmonella typhi and Proteus vulgaris moderate activity against E. coli, Staphylococcus aureus and Bacillus cereus. The remaining strains viz., Enterobacter aerogens, Klebsiella pneumoniae and Pseudomonas aeruginosa were presented less activity. The inhibition zone was recorded and compared with standard antibiotic drug streptomycin. Results support the traditional use of Kigelia africana (Lam) bark as a good source of antimicrobial agent.
