Radical Scavenging Activity and Total Phenolic Content in Selected Fruits and Vegetables

There is a strong association between the intake of fruits and vegetables and the prevention of degenerative diseases due to the presence of antioxidant phytonutrients in them. Therefore, the antioxidant properties of selected fruits and vegetables commonly consumed in Rajasthan were evaluated by the DPPH radical scavenging assay and Superoxide radical scavenging assay. The total phenolic content was determined by the method of Farkas and Kiraly using the Folin-Ciocalteu reagent. The present study suggests that all the tested fruits and vegetables are moderate to potential sources of natural antioxidants.
