TOTAL ANTIOXIDANT CAPACITY IN AQUEOUS EXTRACTS OF SOME COMMON FRUITSAbstract
The present study was aimed to evaluate total antioxidant capacities of eleven different commonly consumed aqueous fruit extracts viz. Ananas comosus, Artocarpus heterophyllus, Carica papaya, Citrullus vulgaris, Citrus sinensis, Malus domestica, Manilkara zapota, Musa paradisiaca, Phyllanthus emblica, Psidium guajava and Pyrus communis. The total antioxidant capacity was assessed using phosphomolybdenum method at different concentrations. Total antioxidant capacity was found to be highest in Phyllanthus emblica (197.5μg of ascorbic acid/mg extract) and lowest in Artocarpus heterophyllus (1μg of ascorbic acid/mg extract). The present research programme underlies the total antioxidant potentials of fruits.
