摘 要 ：从大理白前(Cynanchum forrestii Schltr.)中分离得到2个C21甾体甙，其中一个新甙，命名为大理由前甙A(cynaforroside-A，I)。经光谱分析和化学反应，证明(I)的结构为芫花白前甙元C3-氧-α-L-加拿大麻吡喃基-(1→4)-β-L-加拿大麻吡喃基-(l→4)-β-D-夹竹桃吡喃基(glaucogenin C3－O－α－L－cymaropyranosyl－(l→4)－β-cymaropyranosyl-(l→4)－β-D－oleandropyranoside).

Abstract:Abstract From the crude glycoside of root of Cynanchwn forrestii Schltr, besides one known C21 steroidal glycoside-cynatratoside-B( I ), a new C21 steroidal glycoside named cynaforroside-A( I) was isolated. On the basis of its spectral and chemical evidence, the new compound was deduced as glaucogenin C 3-0-α-L-cymaropyranosyl-( 1→4 )-β-L-cymaropyranosyl-( 1→4 )-β-D-oleandropyranosidc.
