Evaluation of antibacterial potential of Embelia ribes

Antimicrobial activity of Embelia ribes has been evaluated in vitro by employing different concentrations of seed extract. All the concentration inhibited bacterial growth, where as maximum activity was observed at 2000μg. The zone of inhibition increased with the increase in concentration of test solutions. Among the four different bacteria tested, maximum inhibition zone was observed in Escherichia coli (1.32 cm) followed by Pseudomonas aeruginosa (1.24 cm). Low inhibition zones were observed in Staphylococcus aureus (1.21 cm) and Bacilus subtilis (1.14 cm). These studies clearly indicated that the seed of E. ribes has potential antimicrobial constituents.
