Abstract
Fresh mango and commercial mango juices contain various natural antioxidants which have beneficial health effects. In this study, we compared total antioxidant activity of fresh mango (fazlee, amrapali, mohanvog, langra, and gopalvog) juices with that of commercial mango juices (pran frooto, sezan, frutika, and sundrop mango fruit drink), which are available in Bangladesh. Total antioxidant activity was measured by DPPH method. Enzymatic browning in fresh and commercial mango juices was determined by tyrosinase inhibitory assay. The IC50 values of fazlee, amrapali, mohanvog, langra, gopalvog, pran frooto, sezan, frutika, sundrop mango fruit drink juices, vitamin C, and vitamin E were 1.159, 1.367, 0.575, 1.675, 0.725, 0.435, 1.025, 0.925, 0.678, 0.057, and 0.039 mg/ml, respectively. No sample shows tyrosinase inhibitory activity. In conclusion, commercial mango juices can be considered as a good source of antioxidant.
