The Study of Antioxidations and Their Correlations With Anthocyanin Contents in Different Varieties of Mulberry

The correlations between antioxidation and anthocyanin content of dried mulberry fruit from 25 varieties were studied.The results indicated that the ranges of total antioxidant capacity(TAC),scavenging free radical of DPPH capacity(SFRC),anthocyanin contents were 17.80～57.17u/mL,84.5%～18.5%,2.33%～0.09%,respectively,displaying significant genotype difference.According to the hierachical cluster analysis,25 mulberry varieties could be clustered into 5 clusters which consist of 2,11,2,6,4 varieties,respectively.Significant correlations(P0.01) existed between TAC and anthocyanin contents and between SFRC and anthocyanin contents respectively.This shows that the antioxidation of mulberry fruit is closely correlated with its active compositions of anthocyanin.
