Abstract

Introduction: Infectious mouth diseases are caused by microorganisms such as Staphylococcus aureus and Streptococcus mutans. Sentul fruit peel extract contains several phytochemical compounds, flavonoid compounds, saponins and tannins are aromatic hydroxyl groups that act as antibacterial so that they can be used as a treatment for infections of the mouth. This study aimed to determine the inhibitory ability of Sentul fruit peel extract (Sandoricum koetjape) against Streptococcus mutans and Staphylococcus Aureus bacteria which can cause oral infections. Method: Sentul fruit peel simplicia was extracted by maceration method with ethanol for 24 hours. The maceration method was chosen in this study because it is a method that is easy to do and uses simple tools, which is enough to soak the sample in a solvent. A filtering process followed this and the filtrate was then evaporated with a vacuum rotary evaporator at a temperature of 45oC, so that a thick extract was produced. The maceration process was repeated 2 times. After the extraction process, then proceed with liquid-liquid fractionation using distilled water. The thick extract was put into a separating funnel and distilled water was added. Then it was shaken and the aquadest fraction was taken, followed by evaporation with a vacuum rotary evaporator at 45o C, so that the aqua fraction of the ethanol extract was produced. Result:The results showed that the Sentul fruit peel extract was able to inhibit the growth ofS. mutansandS. aureus bacteria as seen from the formation of a clear zone. Based on the ANOVA test, the extract concentration treatment had a significant effect (p<0.005) on the diameter of the clear zone on S. mutansand S. aureus bacteria. Positive control (streptomycin) showed significant differences in Duncan’s test, because it produced the greatest antibacterial activity against test bacteria compared to negative control and various extract concentrations. The diameter of the clear zone in the positive control against S. mutans and S. aureus bacteria were 17.63±0.28 mm and 17.62±1.04 mm, respectively. Sentul peel ethanol extract of aqua fraction at a concentration of 100% gave the highest inhibition zone compared to concentrations of 75%, 50%, and 25%, although it was still smaller than the diameter of the clear zone in the positive control. In bacteria S. mutans, the ethanol extract of Sentul peel aqua fraction at a concentration of 100% gave a clear zone diameter of 14.31±1.06 mm and in S. aureus bacteria it gave a clear zone diameter of 15.34±1.81 mm. Conclusion: Sentul fruit peel extract (Sandoricum koetjape) has the ability to inhibit Streptococcus mutans bacteria and Staphylococcus Aureus bacteria.
