- Abstract
In order to define the difference and correlation of nutritional components and bioactivities of sweet potatoes with different cultivars, the content of nutritional components (dry matter, reducing sugar, soluble sugar, starch, soluble protein, carotenoids, anthocyanin and polyphenols) and bioactivities [ DPPH · scavenging activity, trypsin-inhibitory activity and polyphenol oxidase (PPO) activity] of sweet potatoes cultivars with different flesh colors ( purple, orange, yellow and white) in Zhejiang Province were analyzed by using difference significance analysis, correlation analysis, factor analysis and cluster analysis. The results showed that there were significantly differences in the content of nutritional components in 12 cultivars (P < 0. 05) . The PPO activity of purple flesh cultivars was significantly higher than those of other flesh color cultivars, and showed obvious advantages in DPPH · scavenging activity and trypsin-inhibitory activity. The results of correlation analysis showed that there was an extremely significantly positive correlation between DPPH· scavenging activity and content of soluble protein, anthocyanin and polyphenols. Except for the content of reducing sugar and soluble sugar, trypsin-inhibitory activity and PPO activity were siginificantly correlated with the other nutritional components. The cluster analysis divided 12 cultivars of sweet potato into four categories, and the res ults were consistent with the distribution of each cultivar on the scatter diagram of factor score. The results could provide reference for postpartum utilization and breeding of sweet potato.
