In the present study, acetone extract and sub-fractions of Albizia amara stem bark were evaluated for their free radical potential. The results showed that the crude extract and all the fractions exhibited antioxidant and free radical scavenging activities under different in vitro assays. Among the different fractions, the ethyl acetate fraction exhibited higher DPPH and ABTS radical scavenging activities than the standard quercetin. A. amara stem bark might be valuable source of natural antioxidants that could be used for medicinal and food applications.
