Abstract

The in vitro antibacterial activities of Picralima nitida seed extracts were studied against selected pathogenic bacteria. Seeds were extracted using ethanol, methanol and water. Among the three solvents used, seed extracts of ethanol and methanol were more effective against pathogenic bacteria, where the minimum inhibitory concentration (MIC) ranged between 31.0mg/l to 75.0mg/l and inhibition zone diameter (IZD) of between 11mm to 19mm. All the extracts were ineffective against P. aeruginosa and S. typhi. The antimicrobial activities of the seeds of this indigenous medicinal plant are  discussed in this paper.
