Four triterpenoid prosapogenins named CP_<2b>, CP_<3b>, CP_9 and CP_<10> were isolated from the alkaline hydrolysate of the crude saponin obtained from the root of Clematis chinensis OSBECK. On the basis of chemical and physicochemical evidence, they were characterized as follows : CP_<2b> (I), oleanolic acid 3-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranoside ; CP_<3b> (IV), hederagenin 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside ; CP_9 (V), oleanolic acid 3-O-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-(1→4)-β-D-ribopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside ; CP_<10> (X), hederagenin 3-O-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-(1→4)-β-D-ribopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside.
