Abstract:
3 Beta-acetoxy-(20S, 22E)-dammaran-22-en-25-ol, a new triterpene, was isolated along with five known triterpenes (ursolic acid, oleanolic acid, betulinic acid, 3-epiocotillol acetate, and dimmarenediol II acetate), and alpha-D-glc and sucrose from Radix Ranunculus ternati All of them, except oleanolic acid and alpha-D-glc, were isolated from the family of Ranunculaceae for the very first time, and the NMR data of sucrose was first described. In addition, the absolute configurations of alpha-D-glc and the glucose component of sucrose were determined.
