A New Triterpenoid Saponin from Rhaponticum uniflorum (Compositae)

ZHANG Yong-Hong   


A new triterpenoid saponin, namely unifloroside, together with five known compounds, was isolated from Rhaponticum uniflorum (L.) DC. The structure of the new triterpenoid saponin was elucidated as 3-O-α-L-arabinopyranosyl-urs-9(11),12-dien-28 oic acid β-D-glucopyranosyl ester mainly by using 1D, 2D-NMR techniques and chemical methods.

从祁州漏芦(Rhaponticum uniflorum (L.) DC.)的根中分离得到6个三萜皂甙(16),其中化合物3为一新的三萜皂甙,命名为unifloroside,其结构经1D, 2D-NMR及化学方法鉴定为3-O-α-L-arabinopyranosyl-urs-9(11),12-dien-28-oic acid β-D-glucopyranosyl ester.
