Abstract

The determination of totally phenolic compounds in methanol extracted of cortex fruit of Garcinia manggostana Linn has been done by Folin-Ciocalteau method. The antioxidant activity has been performed using 1,1-diphenyl-2-picrihydrazil (DPPH) as reagent, that measured spectrometrically compared with gallic acid as antioxidant standard compound. The total phenolate compounds found in fresh peel of mangosteen was 1,64±0.18% w/w which calculated as gallic acid equivalence and the antioxidant activity with a value of IC50 was 251,12 μg.
