Shorea accuminatissima, which is known locally as Meranti kuning, is one species of Dipterocarpaceae family.This plant contains compounds that are expected to have antioxidant activity. This research was carried out toexamine the radical scavenger activity of polar fraction of methanolic extract from the tree bark of     S. accuminatissima by using DPPH (2,2-difenil-1-pikrilhidrazil) method with vitamin C as comparator. Powderof tree bark ofS. accuminatissima was macerated in methanol. The methanolic extract was then evaporated toobtained dry extract. Extract with concentration of 200, 100, 50, 25 and 10 µg/mL were used to test its radicalscavenger activity. The result showed that polar fraction of methanolic extract and vitamin has ICvalue of319.83 and 3.72 µg/mL, respectively.Keywords:Shorea acuminatissima, Dipterocarpaceae, polar fraction, antioxidant, DPPH 50
