摘要
Positive-ion fast atom bombardment mass spectrometry appears to be a useful method for the differentiation of anomeric C-glycosides. The mass-analysed ion kinetic energy (MIKE) and collision-activated dissociation (CAD) MIKE spectra of selected positive ions can be used as fingerprints of the alpha- or beta-anomers. The main fragmentation routes and particularly the formation of the [M - H]+ ion and the [M + H - PhCH2OH]+ ion were traced for each anomer.
