Abstract

Flavonoid glycosides (22 compounds) were measured by fast atom bombardment, and the positive and negative ion mass spectra were compared. The mass spectra showed clear molecular ion species. Fast atom bombardment mass spectrometry provided useful information for the structural elucidation of flavonoid glycosides.Positive ion spectra in particular were useful for flavonol 3,7-O-diglycosides, while the negative ion spectra were useful for flavonoid glycoside methyl ether.
