Comparative Study on Antioxidant Capacity of Citrus aurantifolia and Vitex negundo Fruits

In this study, a comparison of antioxidant potential of unripe and ripe fruits of Citrus aurantifolia and Vitex negundo, was carried out. Antioxidant capacity was determined using phosphomolybdenum method, and activity was studied using free radical scavenging activity of 1,1-diphenyl-2-picryl hydrazyl (DPPH). Higher antioxidant activity was reported in unripe fruit juices as compared to ripe fruit juice. Fruit juice samples of both plants showed promising antioxidant activity and those may be employed for various therapeutic purposes to deal with health hazards caused by free radicals.
