Triterpenoids from the Leaves of Ilex hainanensis

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