The Inhibitory Effect of Kaffir Lime Extract towardsStaphylococcus Aureus Bacteria

摘要

Staphylococcus aureus is an anaerobic gram-positive bacterium that becomes one of the causes of infections in the oral cavity. The infections that occur in the oral cavity can be prevented by using a mouthwash. Kaffir lime (Citrus hystrix) contains flavonoid, saponin, tannin and essential oils that have the inhibitory effect on the bacteria by destroying and inhibiting the formation of the bacterial cell wall. This research aims to identify the effect of kaffir lime extracts at various concentration on the growth of Staphylococcus aureus. This in vitro study was conducted in an experimental laboratory. The findings of this study showed that kaffir lime extract at concentration of 12.5%; 25%; 50% and 100% can inhibit the growth of Staphylococcus aureus. It was concluded that the kaffir lime extract has an antibacterial activity.
