Three new dammar-type triterpenoid caffeates (1-3) were isolated from the stalks of Celastrusrosthornianus Loes. Their structures were established through various spectral studies as 3beta,20(S),24(S)-trihydroxyldammar-25-ene 3-caffeate (1), 3beta,20(S),24(R)-trihydroxyldammar-25-ene 3-caffeate (2) and 3beta,20(S),25-trihydroxyldammar-23(Z)-ene 3-caffeate (3), respectively. The three new compounds
