摘　　要：目的:观察不同采收季枇杷叶药材中4种三萜酸成分的变化规律。方法:采用高效液相法对不同季节采收的枇杷叶中4种三萜成分的含量进行检测。结果:科罗索酸、齐墩果酸、熊果酸的含量随月份的变化较小,齐墩果酸和熊果酸含量最高月份为4月,科罗索酸含量最高月份为7月,山楂酸含量变化较大,最高在11月。结论:不同季节采收的枇杷叶中三萜酸类成分的含量变化有一定的规律。Objective： To find out the change regularity of triterpenoid acids content in leaves of Eriobotrya japonica. （Folium Eriobotryae） in different seasons. Method： The content of triterpenoid acids was determined by RP-HPLC. Result： The content changes of oleanolic acid, ursolic acid, corosolic acid were minor in the different seasons. The content of oleanolic acid and ursolic acid were highest in April while the content of corosolic acid was highest in July. The content of maslinic acid has a significant change, the material which collected in November has the highest content in a year. Conclusion： The content of triterpenoid acids changes regularly.
