摘要：
Phytochemical investigation on the leaves of Ilex hainanensis MERR. led to the isolation of four new ursane- and oleanane-based triterpenoids, ilexhainanins A-D (1-4), as well as two known compounds, 2 alpha,3 beta,19 alpha-trihydroxyurs-12-ene-23,28-dioic acid and 2 alpha,3 beta,19 alpha-trihydroxyolean-12-ene-23,28-dioic acid. Their structures were elucidated on the basis of chemical and spectroscopic evidence, and by comparison with literature data.
