异型南五味子藤茎中1个新的木脂素

A novel lignan dimer from stems of Kadsura heteroclita

目的:研究异型南五味子藤茎的化学成分。方法:采用各种柱色谱法分离,通过波谱法进行结构鉴定。结果:化合物1是1个新的二芳基丁烷类木脂素二聚体。结论:五味子科植物中二芳基丁烷类木脂素以二聚体的形式存在属于首次发现。

As a part of our search for bioactive material,the chemical investigation of the stems of Kadsura heteroclita led up to the isolation of a new lignan,heteroclitin R.The structure was elucidated on the basis of nuclear magnetic resonance spectroscopic data.Heteroclitin R was a new compound as a lignan dimer obtained from Schisandraceae family for the first time.
