Mass spectrometry of pennogenin glycosides

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

The electron-impact mass spectra of five unesterified pennogenin glycosides, which contain the M+ or (M - H2O)+ peaks, have been obtained. The characteristic features of the fragmentation of these compounds have been studied. In addition to ions characterizing the successive elimination of carbohydrate units, fragments have been detected which show the breakdown of the terminal pyranose ring. Five new directions of the fragmentation of the spirostanol skeleton due to the presence of an OH group at C-17 have been found.
