摘　　要：从大理白前(Cynanchum forrestii Schltr.)中分离得到2个C_(21)甾体甙,其中一个新甙,命名为大理白前甙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C 3-氧-α-L-加拿大麻吡喃基-(1→4)-β-L-加拿大麻吡喃基-(1→4)-β-D-夹竹桃吡喃甙(glaucogenin C 3-O-α-L-cymaropyranosyl-(1→4)-β-L-cymaropyranosyl-(1→4)-β-D-oleandropyranoside)From the crude glycoside of root of Cynanchum forrestii Schltr, besides one known C21 steroidal giycoside-cynatratoside-B (Ⅱ ), a new C21 steroidal glycosidc named cynaforroside-A ( I ) was isolated. On the basis of its spectral and chemical evidence, (he new corn pound was deduced as gJaucogenin C 3 -O-α-L-cymaropyranosyl-( 1→4 )-βp-L-cymaropyranosyl-( 1→4 )-β-D-oleandropyranoside.
