ANTIOXIDANT ACTIVITY OF SYZYGIUM POLYANTHUM WIGHT EXTRACTS
ABSTRACT: 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 IC50
value of 55.2 mg/ml. In addition, methanol
extract also showed the highest antioxidant activity of ABTS assay among
extracts with IC50 value of 17.41 mg/ml. It indicated that methanol extract of
S. polyanthum Wight leaves potential for antioxidant.
