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.
