摘　　要：从川续断(Dispsacus asper Wall.)根的乙醇提取物中得到二个新三萜皂甙(Ⅶ和Ⅷ)。根据光谱分析、化学反应及双向高效薄层层析结果,证明其结构分别为:3-O-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28-O-β-D-吡喃葡萄糖(1→6)-β-D-吡喃葡萄糖酯甙和3-O-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28-O-β-D-吡喃葡萄糖(1→6)-β-D-吡喃葡萄糖酯甙。Two new triterpenoid glycosides were isolated from the ethanol extracts of roots of Dipsacus asper (Wall). Their structures were deduced as 3 - O -β- D- glucopyranosyl ( 1→3 )- α- L - rhamnopyranosyl ( 1→2 )-α - L - arabinopyranosyl hederagenin 28 - O -β - D - glucopyranosyl ( 1→6 ) -β - D - glucopyranosyl ester (Ⅶ) and 3 - O -α - L- rhamnopyranosyl ( 1→3 ) -β - D- glucopyranosyl ( l→3 ) -α - L-rhamnopyranosyl ( 1→2 ) -α - L - arabinopyranosyl hederagenin 28 - O -β - glucopyranosyl ( 1→6) -β- D- glucopyranosyl ester (Ⅷ), based on spectral analysis and chemical evidences as well as results of 2D- HPTLC.
