The antioxidant activitives of mango peel among different cultivars

Abstract

In this paper, the contents of total phenol and total flavonoid of 8 mango cultivars were determined. Their antioxidant abilities were also evaluated by 1,1-diphenyl-2-pireyhydrazyl (DPPH) radical scavenging, trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP). Correlations between total phenol, total flavonoid and FRAP as well as TEAC were also analyzed. Results showed that mango peels were rich in natural antioxidant compounds the antioxidant abilities were different among different cultivars. The correlations between total phenol, total flavonoid and FRAP indicated phenolics represent a major part of antioxidant capacity in mango peels. This was also useful in the utilization of mango processing waste.
