摘要： To study the difference of polyphenol components and content in different apple strains, the components and content of polyphenol in peel and pulp of 55 apple cultivars, from four strains, were determined by ultra-performance liquid chromatography (UPLC), and liquid chromatography-mass spectrometry (LC-MS/MS). In the present study, a total of 21 polyphenolic components were detected from 55 cultivars, including 16 polyphenolic components in the peel, and 12 polyphenolic components in the pulp. Flavonols and procyanidins were the main components of peel polyphenol, while hydroxycinnamic acid and procyanidins were the main components of pulp polyphenol. The results of principal component analysis and cluster analysis showed that the Delicious-strains could be distinguished from other apple strains due to the high content of procyanidin C1 (PROC1), procyanidin B2 (PROB2), and epicatechin (EPI). Different breeding methods have different effects on polyphenolic compounds. The content of total phenol, flavonols, and hydroxycinnamic acids in the peel of Fuji-strains and Golden Delicious-strains descendants were increased by hybridized breeding, while the content of anthocyanins in the peel of Delicious-strains and Ralls-strains descendants was significantly increased by bud sport breeding. Meanwhile, eight cultivars, including 'Huafu', 'Shinsekai', 'Lysgolden', etc., were selected as breeding parents with high content of flavonols, procyanidins, and hydroxycinnamic acid, which could be used for germplasm innovation of high-polyphenol apple. This study explored the characteristics of polyphenolic components and content in different apple strains, and provided basic materials for functional breeding with high polyphenol content.
