Abstract
The structure of one of the minor compounds, which coexists only with a 25β (S)-spirostanol glycoside (a steroid saponin) such as I, II, XI and XV, was determined to be the corresponding 22β (S)-0, 25α (S) analog Ia, IIa, XIa and XVa, respectively. Since it was believed that all the natural spirostanol glycosides have the 22α (R)-O configuration, these compounds are worthy of note as the first glycosides of 22β (S)-O-spirostanol so far isolated.
