Abstract

The contents of total phenol and total flavonoid of 7 litchi pericarp cultivars were determined. Their antioxidant activities were also evaluated by 1,1-diphenyl-2-pireyhydrazyl (DPPH) radical scavenging and ferric reducing antioxidant power (FRAP). Correlations between total flavonoid and DPPH scavenging capacity as well as FRAP were also analyzed. The results showed that litchi pericarp was rich in natural antioxidant compounds and the antioxidant abilities were different among different cultivars, and this was useful in the utilization of litchi processing waste.
