The aim of the present research was to evaluate the antioxidant potential of ethanol and aqueous extracts of Capparis zeylania. The free radical scavenging activity was found to be high in ethanol extract for DPPH, hydroxyl, superoxide, ABTS and reducing power assays in a concentration dependent manner followed by aqueous extract. The present results supported that the leaf extracts (ethanol and aqueous) of C.zeylanica could serve as potential alternative source antioxidants and can be explored as a good therapeutic agent in the free radical induced diseases.
