- 中文摘要: The isolation and identification of twenty-one components (including four new triterpenoid saponins and one new triterpenoid acid) from the root of Rhaponticum uniflorum (L.) DC. (Compositae) are described. Their structures were determined on the basis of spectral analysis and chemical transformation. The new compounds were identified as 3-O-a-L-arabinopyranosyl-urs-12,18(19)-dien-28-oic acid b-D-glucopyranosyl ester, 3b-hydroxyurs-12,18(19)-dien-28-oic acid b-D-glucopyranosyl ester, 3b-hydroxyurs-12,19(29)-dien-28-oic acid b-D-glucopyranosyl ester, 3-O-a-L-arabinopyranosyl-urs-9(11),12-dien-28-oic acid b-D-glucopyranosyl ester and 2a,3a,19a,25-tetrahydroxyurs-12-en-23,28-dioic acid.
