Abstract

Selaginella intermedia is one of the traditional medicine in East Kalimantan, which use as some traditional medicinal uses. S. intermedia is usually found in the forest floor, especially for this study we obtain from Kebun Raya Unmul Samarinda (KRUS) in East Kalimantan. The aim of this study is to inhibit the radical scavenging agent (DPPH) and antimicrobial assay against Streptococcus sobrinnus and Porphyromonas gingivalis. The control positive of this study is chlorhexidine. The sample extracted with ethanol and obtain 4.33 % extract from extract yield 2.23 g. S. intermedia has a good activity to inhibit radical scavenging agent (DPPH) with a value of 65 % at concentration 100 ppm. S. intermedia also has antimicrobial activity with the minimum inhibitory concentration (MIC) value of 4 mg/ml and minimum bactericidal concentration (MBC) value of 4 mg/ml against S. sobrinus. In a case against P. gingavalis antimicrobial activity with the MIC value of 4 mg/ml and MBC value of 4 mg/ml. The ability of S. intermedia is thought to be due to the presence of secondary metabolites such as alkaloids, flavonoids, and terpene groups. Further research is ongoing to find out deeply about S. intermedia influence on dental caries.
