The glycosides from the traditional Chinese medicine, e.g., digitoxin, glycyrrhizin, and rutin, were studied by the fast atom bombardment mass spectrometry (FAB-MS) and FAB-CA-MIKES. It was found that the accurate mol. wt. and the sequence of their sugars moieties could be obtained directly by FAB-MS and FAB-CA-MIKES. Some useful fragmentation rules of the sugars in the glycosides were reported.
