Antioxidant screening of Garcinia Forbesii originated from Sabah

Abstract Garcinia forbesii is a wild type of plant that have been long used traditionally with broad utilities in several fields like medicines, cosmetics, food and neutraceutics. Increasing awareness towards the use phytochemicals other derives products worldwide has broaden study bioactivities from industrial sectors. Therefore, present aims to screen antioxidant properties fruits leaves by extraction using various types organic solvents which are methanol, ethyl acetate, hexane. The highest yield crude extract both methanol extracts 9.26 ± 0.34 g 7.04 ±0.21 g, respectively. Antioxidant activities leave G. reducing power, FRAP (ferric power) DPPH (2,2-diphenyl-1-picrylhydrazyl) followed same order methanolic > acetate hexanic. Meanwhile, hexane, showed IC50 values at 1.05%, 3.35% 4.44% while for 1.19%, 2.4% 8.94% Methanol therefore better solvent most components leaves.
