| 摘 要： | 分析了25个不同品种桑椹的抗氧化能力与其花色苷含量的相关性。结果表明,25个供试品种桑椹的总抗氧化能力、清除DPPH自由基能力和花色苷含量的变幅分别为57.17~17.80 U/mL、84.5%~18.5%和2.33%~0.09%,表现出明显的基因型差异。25个桑椹品种按系统聚类法可聚类为5大类群,分别包括2、11、2、6和4个品种。桑椹的总抗氧化能力和清除DPPH自由基能力与其花色苷含量之间的相关系数分别为0.815 2和0.876 1,呈极显著正相关(P<0.01?,表明桑椹的抗氧化能力与花色苷含量密切相关。

| Abstract: | 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(P<0.01) 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. |
