The average contents of those constituents in 37 representative cultivars were 1405, 1505, 339, 684, 56, 41, 234, 952, and 147 ?g/g fresh weight (FW), respectively. A significant inverse correlation between the procyanidin contents and the latitude of the geographical origin of the cultivars was observed (r = 0.3851, P < 0.02). Correlation analysis of the levels of the nine compounds in the 37 cultivars yielded a strong correlation (P < 0.001)between the individual levels of the four procyanidins and the sum of the procyanidins level (r = 0.7413?0.9898)and between the flavonoids and the chlorogenic acid (r = 0.5383?0.9212). The changes in level of the nine compounds in the hawthorn fruit were evaluated during maturation using the Hebei Dajinxing cultivar. Sixty-one days after blossom, the polyphenol level reached the highest point and the sum of the contents was 1.36 g/100 g FW.14aHPLC14aHAWTHORN14aCRATAEGUS PINNATIFIDA BGE. VAR. MAJOR N. E.
