摘　　要：从苦绳〔Dregea sinensis var. Corrugata (Sohneid.) TsiangP.T. Li〕的根茎中分到一个新的C_(21)-甾体酯甙成分,命名为苦绳甙乙 (DregeosideB),经光谱分析和化学反应证明,其结构为:苦绳甙元乙 3-0-β-D-夹竹桃吡喃糖(1→4)-β-D-磁麻吡喃糖 (1→4)-β-D-磁麻吡喃糖甙〔DrevogeninB 3-0-β-D-oleandropyra nosy1(1→4)-β-D-cymaropyranosy1(1→4)-β-D-cymaropyranoside〕。A new glycoside, dregeoside B, was isolated form the rhizomes of Dregea sinensis var. corrugata (Schneid) Tsiang et P. T. Li(Asclepiadaceae). The structure of dregeoside B has been deduced on the basis of chemical and spectral evidence as drevogenin B 3-0-β-D-oleandropyrano-syl- (1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside.
