西洋参皂甙的核磁共振波谱研究——Ⅰ.西洋参叶中 Ocotillol型皂甙的结构分析

NUCLEAR MAGNETIC RESONANCE STUDIES OF GINSENOSIDE——Ⅰ. Structure Elucidation of an Ocotillol-Type Saponin Separated From the Leaves of Panax Quinquefolium L.

本文用常规一维~1H、^(13)C核磁共振波谱和远程异核化学位移相关谱。异核化学位移相关谱和同核化学位移相关谱技术研究了西洋参叶中首次分离出的一种Ocotillol型皂甙,确认了化学结构,并对其^(13)C、~1H NMR谱线进行了归属。

In this paper, 2D long-range ^(13)C-~1H heteionuctear chemical shift correlation spectroscopy, in combination with ^(13)C-~1H heteronuclear chemical shift spectroscopy and ~1H - ~1H homonuclear chemical shift spectroscopy, have been used to elucidate the structure of an ocotillol-type saponin (OTS) which was first separated from the leaves of Panax Quinquefolium L. , and the results were also confirmed by element analysis and FAB -MS techniques.
