Antioxidative activity of extracts was measured by rates of carotene bleaching in the coupled oxidation of linoleic acid and b-carotene. Ethanolic-Hexanoic Extract (EHE) of the seed was found to possess the highest antioxidative activity. Furthermore, EHE was fractionated by silica column chromatography and eight major fractions were isolated according to UV absorption. Antioxidative activity of these fractions was evaluated in a b-carotene-linoleate system. Fractions III , I , and II showed the major activity, but fractions I and II have the best value of relative capacity, so they were chosen for further identification. Key words: Seed of Parinarium glaberrimum Hassk, extract, fraction, and antioxidant activity
