摘要:

从北五味子(Schisandra chinensis (Turcz.))的果实中分离并鉴定了3个木脂素类化合物二氢愈疮木脂素(Ⅰ),Gomisin J (Ⅱ)和Gomisin D (Ⅲ), 利用高分辨NMR技术及二维谱(1H-1H COSY、HSQC、HMBC和NOESY) ,对Gomisin J(Ⅱ)和Gomisin D (Ⅲ)的1H和13C NMR数据进行了全归属和较详细的解析.  同时,采用计算机分子模拟实验对结构较为复杂的Gomisin D的立体构型进行了研究. 

Abstract:

Three lignans were isolated from the fruits of Schisandra chinensis bail, and identified as mesodihydroguaiaretic acid(Ⅰ), Gomisin J(Ⅱ) and Gomisin D(Ⅲ) using 1D and 2D NMR techniques. Complete assignment of NMR signals was obtained for compounds Ⅱand Ⅲ. The stereo configuration of Gomisin D was simulated by three molecular simulation methods using the SYBYL software, and the most stable configuration of Gomisin D was calculated.
