✦ Synopsis

The chemical ionization mass spectra of flavonoid glycosides (0-glycosides, C-glycosides and acetylated glycosides) have been investigated. Triethylamine, ethylenediamine, diethylamine, methylamine and ammonia were used as reactant gases. The fragmentation mechanism is discussed, and the perspectives for establishing the molecular weights of glycosides, and the nature of both the sugar residue and the aglycone, are outlined.
