| 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 2α,3β‐dihydroxyurs‐12‐en‐28,30‐olide ( 1 ) and 2α,3β,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. |
