People have been relying on natural plants as a source of treatment for various diseases even today that is still the case especially in rural areas where traditional healers outnumbers western doctors. Most medicine used by western doctors is also derived from natural plants. The aim of this study was to investigate the antioxidant potential of Philenoptera violacea and Xanthocercis zambesiaca leaves, flower & twig extracts. These two plants were chosen from 60 plants found in Africa and belonging to the Fabaceae family. The scavenging activities of the Xanthocercis zambesiaca extract and Philenoptera violacea was determined by 2, 2- diphenyl-1-picrylhydrazyl (DPPH) assay and was compared with standard antioxidant (ascorbic acid). Xanthocercis zambesiaca showed moderate (50%) free radical scavenging activity, while Philenoptera violacea extract had low free radical scavenging activity at the concentration of 2.5 mg/ml when compared to ascorbic acid. Our results indicate that, Philenoptera violacea plant extract showed low antioxidant activity while Xanthocercis zambesiaca extract exhibited a moderate dose dependent antioxidant activity and the latter can be considered as a weak source of antioxidant.
