The contents of six phenolic compounds and three organic acids in pulp of 257 peach germplasms were determined by High-Performance Liquid Chromatography(HPLC),the mono-phenol and total phenol contents in different germplasms were compared,and their contents in different types of germplasm resources with different pulp color,pulp texture and organic acid content were discussed. The results showed that the contents of total phenol in peach pulp ranged from 31.05 to 919.11 mg · kg-1 FW,among which the contents of chlorogenic acid,neochlorogenic acid and catechin were highest,the mean values were 56.60,43.20 and 25.79 mg · kg-1 FW,respectively,the average contents of epicatechin and rutin were 14.77 and 14.85 mg · kg-1 FW,respectively,and the content of ferulic acid was lowest with 1.57 mg · kg-1 FW. Eleven special varieties were selected according to the mono-phenol and total phenol contents. In different types of pulp color,the total phenol content in red pulp were significantly higher than those in white and yellow pulp(P < 0.05),the total phenol content of yellow pulp was no significant difference with white pulp. In different types of pulp texture,the phenolics content of crisp peach were significantly higher than in melting and stony hard peach(P < 0.05). The total phenol content was significantly correlated with the contents of malic acid,citric acid and quinic acid in pulp.
