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.
