DPPH radical scavenging assay measures the hydrogendonating capacity of the antioxidant to the stable free radicalDPPH, resulting in the formation of diphenylpicrylhydrazine(Shon et al., 2003). Antioxidant activity may be indicatedby the reductive ability of a compound (transformation offerricyanide complex to ferrocyanide complex) as describedby Rama Prabha and Vasantha (2011).
