The reduction capacity of stable DPPH radicals was determined by decrease in its absorbance at 517 nm induced by the
antioxidants present in extracts and the results are illustrated in Fig. 1. All extracts showed tendency to quench the DPPH
radicals in a concentration-dependent fashion. AqME proved a potent free radical scavenger and showed DPPH inhibition followed by AqE, ME and AE, respectively, at 1 mg/ml concentration. Many authors have attributed higher free radical scavenging ability of plants to their phenol contents and their ability to donate hydrogen atom. Likewise OH radical scavenging activity was also observed maximum in AqME (Fig. 2).
