【摘要】 从苦绳（Dregea sinensis var. corrugata）的根茎中分得一个新的C₂₁-甾体甙成分,命名为苦绳甙甲（dregeoside A）。经光谱分析和化学反应证明,其结构为:苦绳甙元甲3-O-3-O-甲基-6-去氧-β-D-阿洛吡喃糖（1→4）-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（drevogenin A 3-O-3-O-methyl-6-deoxy-β-1）-allopyranosyl-（1→4）-β-D-oleandropyranosyl-（1→4）-β-D-cymaropyranosyl-（1→4）-β-D-cymaropyranoside).更多还原

【Abstract】 A new glycoside, named dregcoside, was isolated from the rhizomeof Dregea sinensis var. corrugata (Asclepiadaceae). The structure of dregeusideA was deduced on the basis of chemical and spectral evidence as drevogenin A 3 -0- 3 -O-methyl- 6 -deoxy- β-D-allopyranosyl-(1→ 4 )- β-D-oleandropyranosyl-( 1→4 )-β-D-cymaropyranosyl-( 1→4 )-β-D-cymaropyranoside).更多还原
