从川续断(Dipsacus asper Wall.)根的乙醇提取物中得到二个新三萜皂甙(Ⅸ和Ⅹ),根据光谱分析和化学反应,其结构分别确定为3-O-[β-D-吡喃木糖(1→4)-β-D-吡喃葡萄糖(1→4)][α-L-吡喃鼠李糖(1→3)]-β-D-吡喃葡萄糖(1→3)-α-L-吡喃鼠李糖(1→2)-α-L-吡喃阿拉伯糖-常春藤皂甙元(Ⅸ)及其28-O-β-D-吡喃葡萄糖(1→6)-β-D-吡喃葡萄糖酯甙(Ⅹ)。 Two new triterpene saponins (IX and X) were obtained from the ethanol extract of the root of Dipsacus asper Wall. According to spectral analysis and chemical reaction, the structures were determined as 3-O-[β-D- Glucopyranose (1→4)-β-D-glucopyranose (1→4)] [α-L-rhamno rhamnose (1→3)]-β-D-glucopyranose (1→ 3)-α-L-rhamrhampyr (1→2)-α-L-pyrantosyl arabinose-Ivy saponin (IX) and its 28-O-β-D-glucopyranose (1→ 6) -β-D-glucopyranosyl ester (X).
