The result shows that the ethanolic extracts showed more antibacterial activity than the aqueous extracts. The extracts displayed potent antimicrobial activity against the test organisms which were Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, Bacillus subtilis, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger, the minimum inhibitory concentration ranges from 2.5-15mg/ml in all the plant extracts.
