The isolated of phenolic compound from ethyl acetate extract of stem bark of Garcinia sizygiifolia have been isolated. The extraction was done by maseration and separation and purification by chromatography method. The structure of this compound was determined based on spectral data including IR, UV, NMR 1-D and NMR 2-D. The antioxidant activity of the isolated compound was tested by DPPH method. The isolated compound was a yellow solids (50 mg) with melting point 198-199°C. The analysis spectral UV showed maximum absorption at Ama* 214 nm derived from the methanol solvent, and at Ama* 271 nm showed that there is electronic transition n —» 7t*. IR spectral showed characteristic absorption for -OH (3132.40 cm'1), -C=0- (1651.07 cm'1), -C-H aromatic (3082.25 cm'1), -C=C- aromatic (1618.28 ; 1562.34 ; 1456.28 cm'1) and -C-O- alcohol (1238.30 cm'1). 'H-NMR spectral showed signal at
