M. Pugalenthi et al: Evaluation of Antioxidant activity Malus domestica & Phaseolus vulgaris

The aim of this study was to determine the antioxidant activity as well as total phenol (TPC) and total flavonoid content (TFC) in two fruits, apple (Malus domestica) and green beans (Phaseolus vulgaris). The antioxidant activities were examined by two different methods namely DPPH free radical scavenging activity and reducing power scavenging activity. The results showed that considerable amount of TPC and TFC was present in these fruit extracts as well as these vegetables contain a vast array of different phytochemicals in their dry form. Apple showed higher antioxidant activity than green beans. Phytochemical screening revealed the presence of saponins, steroids, flavonoids and carbohydrates & glycosides in all the extracts. Overall, the present results provided basic data for choosing these fruits with high antioxidant capacity for consumption or for the development of antioxidant based medicines as value-added products.
