摘　　要：从喙柱牛奶莱(Marsdenia oreophila)茎中分得11个化合物,其中9个经波谱分析和与标准品比较分别鉴定为:noreugenin(Ⅰ), eugenin(Ⅱ), 2,5-dimethoxy-1,4-benzo-quinone(Ⅲ), syringaresinol(Ⅳ), β-amyrin acetate(Ⅴ),α-amyrin(Ⅵ),β-sitosterol(Ⅶ), dau-costerol(Ⅷ), syringic acid(Ⅸ)。化合物(Ⅰ)、(Ⅱ)、(Ⅲ)、(Ⅳ)、(Ⅸ)均为首次从该属植物中分得。其它化合物结构正在鉴定中。Eleven chemical constituents were isolated from the stem of Marsdenia oreophila. Nine of them were identified as noreugenin(Ⅰ ),eugenin( Ⅱ ), 2, 5-dimethoxy-1, 4-benzoquinone( Ⅲ),sy-ringaresinol ( Ⅳ ) ,β-amyrin acetate ( Ⅴ ) ,α-amyrin( Ⅵ) ,β-sitosterol(Ⅶ ) ,daucosterol(Ⅷ)and syringic acid ( Ⅸ )on the basis of spectral analysis and comparison with authentic samples. The compounds of ( Ⅰ) , (2Ⅱ ) , ( Ⅳ )and ( Ⅸ )were isolated from this genus for the first time.
