Antibacterial activity of different fractions of Commelina benghalensis L

In Bangladesh the herb Commelina benghalensis L. is used for otitis media, suppurative sores, burns, conjunctivitis and skin diseases (eczema, abscesses, acne, scabies and warts) although the compounds responsible for the medicinal properties have not been identified. In this study the plant was evaluated for antibacterial activity and the extracts (ethanolic, petroleum etheric, diethyl etheric, methanolic and aqueous) were found to possess maximum potency against infectious pathogens Staphylococcus saprophyticus, Staphylococcus aureus, Enterococcus faecalis, Staphylococcus pyogenes, Streptococcus agalactiae, Salmonella typhi, Escherichia coli, Shigella boydii, Shigella dysenteriae and Pseudomonas aeruginosa. The zone of inhibition was observed with almost all bacteria with some exceptions. Minimum inhibitory concentrations of the extracts were found to be significant.
