The purpose of this study was to test the antioxidant activity of the leaf extract of kayu bulan (Pisonia alba Span.). The method of extraction in this study using maceration with ethanol 40, 60 and 80%. The extract obtained is determined phenolic content and antioxidant activity assay with DPPH (1,1-diphenyl-2-picrylhydrazyl). Based on the results obtained in leaf of kayu bulan has a total phenolic content of 12.45, 16.22, 28.67 (mg / kg) to extract 40, 60 and 80 %, respectively. Based on the results of the calculation of IC50 showed that extract had IC 50 values ​​ are 544.44, 478.12 and 236.50 ppm for 40, 60 and 80 %, respectivel
