title: Triterpenoids from the roots of Actinidia chinensis.
abstract: Two new triterpenoids, 1 and 2, were isolated from the hepatoprotective AcOEt fraction of the roots of Actinidia chinensis, together with eight known 12-en-28-oic acids of oleanane or ursane type, 3-10. The two new compounds were elucidated as 2alpha,3beta-dihydroxyurs-12-en-28,30-olide (1) and 2alpha,3beta,24-trihydroxyurs-12-en-28,30-olide (2), on the basis of spectroscopic (IR, NMR, and MS) analyses. The chemotaxonomic significances of some triterpenoids were also discussed.
