Abstract: In the present study, to investigate antibacterial activity of hexane and methanol extract of clove (Syzygium aromaticum L.). The in vitro antibacterial activity was performed by agar well diffusion method. The clove extracts inhibit the growth of bacterial species such as two gram negative E.coli, Pseudomonas aeruginosa and gram positive Staphylococcus aureus, Bacillus cereus. Methanol extract of clove revealed highest zone of inhibition in E.coli, whereas hexane extract of clove showed highest activity against Bacillus cereus. The results obtained from this study suggest that the methanol and hexane extracts of Syzygium aromaticum L. revealed a significant scope to develop a novel broad spectrum of antibacterial herbal formulation.
