Guttiferron F and essential oil were isolated from extractàn-hexane ofàGarcinia cf bancanaàMiq. Antioxidant activity was done by DPPH method toààn-hexane, methanol, ethyl acetate, n-butanol extracts and Guttiferron F, showed activity with IC50 24.5, 22.4, 29.2, 37.6 and 25.8 õg/mL respectively. The structure elucidation of Guttiferon Fàbased on spectroscopy data of IR, NMR of 1H and 13C.
