摘要： Peach fruits are rich in phenolic compounds and have considerable health benefits. In this study, 19 proan-thocyanidins (PACs) and 37 other phenolic compounds are identified and evaluated in the mature fruits of 217 peach accessions using LC-QTRAP-MS/MS and LC-QTOF-MS analyses. Total PAC quantities ranged from 18.93 to 697.52 mu g/g fresh weight with a variance of 36.8-fold, and accounted for 11.2 % -85.6 % of total phenolics content. Kaempferol-3-O-rutinoside (0.001-0.968 mu g/g), isorhamnetin-3-O-rutinoside (0.001-0.300 mu g/g), taxi-folin (0.006-0.078 mu g/g), luteoloside (0.002-0.068 mu g/g), prunin (0.043-33.333 mu g/g), phlorizin (0.018-1.100 mu g/g), and trans-piceid (0.013-0.472 mu g/g) were also highly diverse. The fruit ripening period, breeding back-ground and fruit type significantly influenced the PACs and phenolic glycosides. This study presents a complete profile of PACs and other major phenolics in 217 peach germplasms, and is expected to aid future peach breeding procedures targeted at producing plants rich in specific phenolics.
