不同柿种质雄花表型、活性成分及体外抗氧化活性
Phenotypic characteristics,active components and antioxidant activities of the male flowers of different Diospyros materials
摘要
Abstract
In order to systematically evaluate the phenotypic characteristics,active components contents,and antioxidant activities of male flowers of different Diospyros materials,8 kinds of materials were measured by spectrophotometric and HPLC methods.The results showed that high degree and great range existed in phenotypic characteristics,with the coefficient of variation ranging from 0％ to 61.37％,with 54.95％ on average.There were significant differences in flavonoids,polyphenols,tannin and vitamin C contents,with the coefficient of 51.65％、40.19％ 、18.87％ and 109.10％,respectively.The antioxidant activities including DPPH ·,ABTS + · scavenging ability,Fe3+ and Cu2+ reducing ability,the chelating ability of Fe2+ and Cu2+ was excellent,and they were significantly correlated with active components and no significant correlation with phenotypic characteristics.According to principal component and cluster analysis,three principal components with the cumulative contribution rates reaching 78.900％were obtained from twenty tested indexes.In addition,the eight materials were divided into four groups and selections should be made according to different targets for development and utilization in the further.关键词
