Abstract

Crude extracts of applee peel were prepared by soxhelt extraction method with solvents methanol, ethanol, dichloromethane, acetone, hexane and ethyl acetate. Extracts were subjected for the measurement of total phenolic content (TPC) by Folin-Ciocalteu method as well as flavonoid content, chelating activity, reducing power and antioxidant/radical scavenging activity [1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical scavenging activity]. Results for all samples were in agreement with each other. The results revealed that all extracts of the apple peel exhibit antioxidant activity. These findings suggest that the apple peel extracts could act as potent source of antioxidants.
