Abstract

Four triterpenoid prosapogenins named CP_2b, CP_3b, CP₉ and CP₁₀ 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 ; CP₉ (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 ; CP₁₀ (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.
