Abstract：Grape contains a series of components which are beneficial to human health. Portuguese polyphenol is one of the most important active components. In view of the development and utilization of natural active ingredients in fruit thinning, the reuse of waste, in this paper, we measured the content and difference of polyphenol and flavone from 13 kinds of grape prethins. The DPPH radical scavenging ability, hydroxyl radical scavenging ability and reducing power were measured to evaluate its functional activity, and the correlation between the functional components and activity was established. The results showed that the content of polyphenols and flavonoids of "Moldova", "A17" and "Gold finger" were significantly higher than that of other varieties, and the antioxidant activity was also better than those of other varieties.
