Abstract
In the course of our continuing studies on the chemical constituents of Rhoipteleaceae from the chemotaxonomical point of view, twelve dammarane-type triterpene glycosides, chilianosides A-L, were isolated from the leaves of Rhoiptelea chiliantha DIELS et Hand.-MAZZ. (Rhoipteleaceae). Their structures were elucidated on the basis of spectral and chemical evidence. Chilianosides B-G possess hydroperoxyl groups in the molecules, whereas chilianosides H-L are the hydroxyl analogues of chilianosides B-G. All of the chilianosides have 20-R configurations.
