北玄参根中的一个新环烯醚萜衍生物

A new iridoid derivative from the roots of Scrophularia buergeriana

摘要: 从北玄参块根中发现了一个新的环烯醚萜衍生物，命名为buergerinin （1）。通过质谱和一、二维核磁共振谱等分析，鉴定了该新化合物结构，并命名为rel-（1R，5R，6R）-（2-oxa-bicyclo3.3.0oct-7-en-6，7-diyl）dimethoxy；propane。

Abstract: Phytochemical investigation of the roots of Scrophularia buergeriana Miq. (Scrophulariaceae), resulted in the isolation of a new iridoid derivative named as buergerinin (1). Its structure was elucidated as rel-(1R, 5R, 6R)-(2-oxa-bicyclo3.3.0oct-7-en-6, 7-diyl)dimethoxypropane based mainly on MS and 1D and 2D NMR spectroscopic analyses.
