Abstract

The antibacterial activity of the plant extract was tested against representative gram-negative bacterium (Escherichia coli) and gram-positive bacterium (Staphylococcus aureus). All three concentrations exhibited an inhibition on the test microorganisms. The 100% concentration of the plant extract exhibited the largest zone of inhibition compared to 50% concentration and the control groups which are Vancomycin (+) and ethanol (-) against S. aureus. Against E. coli, the 100% concentration of the plant extract had also the largest inhibition among the 50% concentration, Ampicillin (+) and ethanol (-). Data were analyzed using one-way ANOVA and was represented through mean ±SD. The results implied that the plant extract was much more potent substance compared to the commercial antibiotic. Therefore, the researchers came up with a conclusion that the antibacterial activity of Eugenia caryophyllus was rather efficient against the Staphylococcus aureus and Escherichia coli.
