Ethanolic extracts of pods of Moringa oleifera and Cassia fistula were taken for antioxidant activity and free radical scavenging activity. The pods of Moringa oleifera and Cassia fistula exhibited significant reducing power and free radical scavenging effect on TAC, FRAP, FTC, TBA and MTT. All these antioxidant activities were concentration dependent which were compared with standard antioxidants such as BHA, ascorbic acid, BHT and rutin. In addition, total phenolic content and flavonoids was determined as gallic acid and quercetin equivalents respectively. The highest free radical scavenging of pod extract was observed at concentration of 1mg/ml for Moringa oleifera and for Cassia fistula.
