In-vitro antioxidant activities of the fruit peels of Citrus macroptera were studied in the present work. Ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays were performed to evaluate the antioxidant properties of the fractions from n-hexane and methanol crude extracts from the fruit peels of this plant. Results suggested that all fractions from methanol crude extract showed good antioxidant activities. Meanwhile, all fractions from n-hexane extract exhibited as weak antioxidant properties. The results were comparable with standard ascorbic acid. The potency of antioxidant activities of the fruits peel of C. macroptera depends on the type of extracts.
