In Europe, the standard extracts of the leaves and flowers of hawthorn (Crataegus oxyacantha or Crataegus monogyna) have been used for treating mild congestive heart failure (NYHA II). Flavonoids and procyanidins were considered as the most important active components in them. These components in European hawthorn leaves have been analyzed by HPLC method. In China, the extracts of leaves of Chinese hawthorn have also been developed into preparations and have been included in Chinese Pharmacopoeia. Hu et al. 7 have analyzed the content of vitexin in dried leaves of C. pinnatifida by HPLC. Li et al. determined vitexin-2′′-rhamnoside of Chinese hawthorn leaves at different growth time. Liu et al. compared the concentrations of seven flavonoids and chlorogenic acid in dried leaves of Crataegus L from eight province of China. Besides, the content of procyanidins, another group of important polyphenols in Chinese hawthorn leaves, has not been reported. Recently, we isolated a compound with typical fragrance from Chinese hawthorn fruits and confirmed it is eucomic acid; which is a kind of secondary metabolite rarely seen in plants and is mentioned in previous papers. Ding et al. reported Quantification of Ten Polyphenols in the Leaves of Chinese Hawthorn (Crataegus pinnatifida Bge. var. major N.E. Br.) by HPLC
