Abstract

The walnut shell and apricot fruit were subjected to test under various methods i.e. Folin-ciocalteu methods, DPPH radical scavenging assay and metal chelating assay method. The findings exhibited that the radical scavenging activity of walnut fruit and shell was found to be 77.45% and 76% respectively which is quite significant. On the other hand apricot fruit showed a week activity i.e. 6.52%. A standard antioxidant ascorbic acid was run parallel to compare the results it showed 91%. Results regarding actual potency to scavenge radicals indicated that walnut fruit showed promising potential against DPPH radicals and its IC50 value was found to be 1.28 µg/mL, which indicates it greater potency than standard antioxidant ascorbic acid (4.6 µg/mL). The walnut shell also showed a significant activity and its IC50 was determined to be 6.62 µg/mL which is comparable activity with ascorbic acid.
