摘要：

Gas chromatography coupled to methane chemical ionization mass spectrometry was used for qualitative determination of trifluoroacetylated plant glycosides. The mass spectra obtained exhibited characteristic fragment ions of the sugar moiety and molecular or pseudo-molecular ions. The pattern of these chemical ionization spectra was influenced by source temperature. This method was applied to the structural determination of glycosides from purple passion fruit and muscat wine (Muscat of Frontignan) extracts obtained by adsorption on Amberlite XAD-2.
