Introduction: Methanol extract of X. moluccensis was found to be significantly effective in scavenging DPPH method. Therefore, this research is a follow-up research study from Budiarso et al (2020).. The methanol extract was then fractionated and tested for antioxidant activity. Objective: To assess antioxidants activity of methanolic fractions from stem bark of Kayu Sarampa. Method: The Stem bark was extracted with Reflux method using hexane, ethyl acetate, and methanol as solvent. The methanolic extract was fractionated using a chromatographic column were subjected to the antioxidant activity assay by the 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and the ferric-reducing antioxidant power (FRAP) method. Results: F3 Fractions IC50 of X. moluccensis exhibits the highest DPPH scavenging activity compared with F2, F3, ascorbic acis as control positif, F5, and F4, wich are 4.64, 6.79, 9.69, 10.49, and 227.44 respectively and Ferric reducing power from methanolic fraction of X. moluccensis stembark F3 exhibits higher antioxidant power compared to F2, F1, F5, ascorbic acid and F4, respectively which are 667.8 μmol/gr, 607.8 μmol/gr, and 573.8 340.48 and 309.8 μmol/gr, respectively
