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 α ,3 β ,19 α ‐trihydroxyurs‐12‐ene‐23,28‐dioic acid and 2 α ,3 β ,19 α ‐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.
