摘　　要：目的:比较枇杷成年生长叶和落叶中三萜和黄酮类成分含量的差异。方法:采用高效液相方法测定两种叶子中齐墩果酸和熊果酸的含量,采用紫外分光光度法测定两种叶子中总黄酮的含量。结果:两种叶子中的三萜和黄酮类成分含量有显著差异。结论:落叶中的齐墩果酸和熊果酸含量高于成年生长叶,总黄酮含量低于成年生长叶。AIM ： To compare the content of triterpenoids and flavonoids between the adult leaf and the defoliation of Eriobotrya japonica （ Thunb. ） Lindl. METHODS ： The content of oleanolie acid and ursolie acid were determined by HPLC, the content of total flavonoid was analyzed by UV speetrophotometer. RESULTS ： The contents of triterpenoids and total flavonoids in the adult leaf and the defoliation have significant difference. CONCLUSION： The contents of oleanolic acid and ursolic acid in defoliation are higher than that in the adult leaf, but the content of total flavoniod in defoliation are significantly lower than that in the adult leaf.
