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.

Keywords: Antibacterial activity; Solanum surattense; pathogenic
micro organisms.
