Abstract : Fruit of eight mango genotypes were evaluated for antioxidant potential by several biochemical assays (DPPH, ABTS, ORAC, FRAP, SASR and MCC) and tested for their polyphenol composition and vitamin C contents. The significance analysis demonstrated that the antioxidant capacity of Tainong 1 fruits were significantly higher than that of other genotypes, which was about 2.1-6.3-fold higher than Guifei assayed in ABTS, DPPH, ORAC and FRAP methods. The total polyphenols and flavonoids contents showed a great variety amongst mango genotypes and highly correlation with the total antioxidant capacity. It is concluded that significant genotypic difference exists in the total antioxidant capacity of mango fruits. Both total polyphenols and flavonoids are major contributors to the total antioxidant capacity in mango fruit.
