Abstract:
Abstract. The antioxidant activity of white kapul (Baccaurea macrocarpa) fruit rinds was
investigated in this research. Baccaurea macrocarpa fruit rinds were extracted with n-hexane,
ethyl acetate, and methanol, consecutively. All extracts were determined for their antioxidant
activity based on the DPPH method. The yields from hexane, ethyl acetate, and methanol extract
were 0.14%, 0.64%, and 0.94%, respectively. The highest antioxidant activity was observed in
methanol extract (IC50 22.968 ppm), followed by the activity from ethyl acetate extract (IC50
29.741 ppm), and hexane extract (IC50 141.931 ppm). As a comparison, the IC50 of vitamin C
was 5.019 ppm.
