Antioxidant activities of Syzygium polyanthum Wight leaves extracts (methanol, ethyl acetate, dichloromethane, and hexane) were evaluated by using DPPH (2, 2-diphenyl-2-picrylhydrazyl hydrate) and ABTS (2, 2’-azinobis (3-ethylbenzothiazole-6-sulfonic acid) methods. The methanol extract showed the highest antioxidant activity of DPPH assay among extracts with IC 50 value of 55.2 mg/ml. In addition, methanol extract also showed the highest antioxidant activity of ABTS assay among extracts with IC 50 value of 17.41 mg/ml. It indicated that methanol extract of S. polyanthum Wight leaves potential for antioxidant.
