Abstract
ABSTRACT
Has done research about antioxidant activity of suweg tuber (Amorphophallus campamulatus) based on the level of polar solvent. This research begins with in phased maceration extraction using n-hexane, ethyl acetate dan ethanol. Next step was antioxidant activity test with tyocyanate to n-hexane extract and DPPH methods to ethanol extract, ethyl acetate and vitamin C. The result showed antioxidant activity in n-hexane extract i.e. 14,96 %, end 77,13 % BHT while in ethyl acetate, ethanol and vitamin C reached IC50 value are 458,102 ppm, 223,268 ppm dan 26,76 ppm.
Keywords: Suweg tuber, type of solvent, maceration, antioxidant
