Abstract

Preliminary study on the antioxidant activity of 20 species from the family of Mimosaceae was carried out by evaluating their free radical scavenging activity. In this study, the ethanolic extracts of pericarp, seeds, leaves and bark were allowed to react with the DPPH free radical to give a simple method but gave reliable results. Results were expressed as the concentration of the extracts necessary to inhibit the initial DPPH concentration by 50% (IC50). From the IC50 the free radical scavenging activities of the extracts were compared with BHT and Quercetin. Among the extracts, the Xylia xylocarpa extract showed the highest inhibition with IC50 less than 0.1 μg/ml.
