Antibacterial Activity of <i>Solanum surattense</i> Burm. F

Abstract

Ethanol extracts of Solanum surattense used in traditional medicine for treatment
of various infections. The antibacterial activity detected was against Staphylococcus aureus, Streptococcus sp.; Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysenteriae and Vibrio cholerae. The highest antibacterial activity was observed in 500μg concentration of leaf extracts of all bacteria screened except Shigella dysenteriae. The minimum zone of inhibition observed in 25μg concentration of leaf extract except Pseudomonas aeruginosa and Shigella dysenteriae. These results indicate that the extracts were bacteriostatic at higher concentrations.
