Nephelium ramboutan-ake, is a species of Sapindaceae family, locally named Maritam from Kalimantan. However, there is limited information about the potency of this plant. The present study’s objective was to carry out the antioxidant and antibacterial activity of N. ramboutan-ake leaf extract by three different solvents of extraction. The extracts obtained by successive solvent extraction from the maceration method use n-hexane, ethyl acetate, and ethanol solvent. Antioxidant activity was analyzed by DPPH radical scavenging assay compared to ascorbic acid. Antibacterial activity was assayed using the 96 well-plate microdilution broth method against Streptococcus mutans and S. sobrinus compared with chloramphenicol as a positive control. This research showed that ethanol extract was the highest yield, followed by ethyl acetate and n-hexane extract. All extracts potentially scavenged DPPH free radicals at a concentration of 25, 50, and 100 ppm. These plant extracts also could inhibit all tested microorganisms. N. ramboutan-ake can be used as a source of natural medicinal material.
