Keywords: Antibacterial activity, nutmeg extract, Streptococcus viridans


Background: Antibacterial is a substance that can disturb bacteria growth activity or eliminate it. Nutmeg is one of the natural substances that have antibacterial activity, such as essential oil, saponin, and alkaloid.

Objective: This study aimed to determine the antibacterial activity of nutmeg extract in inhibiting Streptococcus viridans growth.

Methods: This is a quasi-experimental with posttest only control group design. Distilled water was used as the negative control group; chlorhexidine gluconate 2% was used as the positive control group; the treatment group used nutmeg extract with concentrations of 16%, 12%, 8%, and 4%, respectively. Antibacterial activity testing using agar diffusion (Kirby-Baurer Discs) with Shapiro-Wilk test data analysis, Levene-Test, one-way ANOVA test, and Post-Hoc Test.

Result: The result showed that nutmeg extract has an antibacterial effect on the Streptococcus viridans with the most inhibitory zone, at 16% concentration (8,34 mm), while in the positive control the inhibition zone was (17.26 mm).

Conclusion: This study concluded that nutmeg extract at a concentration of 16%, 12%, 8%, and 4% have an antibacterial effect in inhibiting the growth of Streptococcus viridans, but is not as effective as chlorhexidine gluconate 2%.
