Two new C21 steroidal glycosides from Marsdenia tenacissima

    摘要
  • 摘要: 目的研究中药通光藤的化学成分。方法用现代色谱技术分离化合物,用化学方法及现代光谱技术(IR,UV,MS,1HNMR,13CNMR和各种2D-NMR技术)对所得化合物的结构进行鉴定。结果从云南昆明产通光藤茎中分离得到2个化合物,分别鉴定为通光藤苷J(tenacissosides J,I)和通光藤苷K(tenacissosides K,II)。结论化合物I和II均为新化合物。

     

    Abstract: AimTo study the chemical constituents of Marsdenia tenacissima (Roxb.) Wight et Arn. MethodsTo separate compounds with various chromatography technology and to elucidate their structures by chemical and spectral analysis. ResultsTwo compounds were isolated from Marsdenia tenacissima and their stuctures were determined as tenacissosides J (I) and tenacissosides K (II). ConclusionCompounds I and II are new C21 steroidal glycosides.
