ANTIOXIDANT ACTIVITY OF FRUITS AVAILABLE IN AIZAWL MARKET OF MIZORAM, INDIA
The antioxidant activity of the fruits available in the Aizawl market of Mizoram, India was estimated. A total of 20 fruits were evaluated for their antioxidant activity based on the ability of the fruit extracts to scavenge 1,1-diphenyl-2- picrlyhydrozyl free radicals, to reduce ferric ions determined by ferric reducing antioxidant potential assay and total phenolic content determination. The antioxidant activity was expressed as mg Trolox equivalents for 1,1-diphenyl-2-picrlyhydrozyl free radicals scavenging assay and FRAP ass ferric reducing antioxidant potential assay while the total phenolic content was expressed as mg Gallic acid equivalent per 100 gm of edible portion of the fruits. The antioxidant activity observed by the three methods does not vary markedly though the values obtained by 1,1-diphenyl-2-picrlyhydrozyl free radicals scavenging assay was highest among the three methods and least in total phenolic content determination. Among the fruits used in the present investigation, the highest antioxidant activity was observed in Amla and least in coconut water
