摘要:

根据天然9,19-环菠萝蜜烷型三萜皂苷的7种结构类型,对其光谱学特征(红外、质谱、一维和二维核磁共振谱)进行了归纳和总结.这项工作对于区分此类骨架的不同结构类型、确定取代基的位置及其立体化学极为有帮助.

Abstract:

This paper deals with the main spectroscopic features (IR,MS,1H NMR,13C NMR, 2D NMR) of natural,9,19-Cyclolanstane triterpenic glycosides according
to various structural types. On the basis of systematic analysis of the spetroscopic characteristics due to various chemical environments, it proved possible to differentiate various structural types, as well as to decide the location and stereochemistry of some substituted groups. All these findings are helpful for st
ructural elucidation and assignments of the spectroscopic signals of such compounds.
