    Introduction: This study examined the antioxidant activity and phenolic, flavonoid and saponin contents from mul-tiple solvent extracts of Albizia myriophylla (ABZ) bark. Antioxidant activity of the methanol extract and its derived fractions namely hexane, chloroform, ethyl acetate, butanol and a residual aqueous fraction of the bark of ABZ was assessed. Methods: All the extracts showed a significant presence of phenolic, flavonoids and saponins. In DPPH (1, 1-diphenyl-2-picrylhidrazyl) radical scavenging test, ABTS (2-2’-azinobis 3-ethyl-6-sulfonic acid) radical scavenging test and reducing activity on ferrous iron (FRAP) test, the total antioxidant capacity was found to be varied in different fractions. Results: The IC50 calculated value of the three assays showed that the methanolic extract of ABZ bark had the lowest IC50 value for each assay, compared to the other extracts signifying highest anti-oxidant activity. Methan-olic extract of ABZ was tested in high-fat diet induced mice, which showed reduce adipocyte cellularity and reduces the cholesterol, triglyceride, LDL level while increasing the HDL level. Conclusion: The antioxidant capacity with probable free radical scavenging activity of the methanolic extract of ABZ may be useful for the treatment of chronic inflammatory-related metabolic diseases such as obesity.
