摘要
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.
