| Abstract: | The chemical ionization mass spectra of a representative selection of flavones, flavonols, flavanones, and flavanols have been examined, using methane as the reagent gas. The flavones and flavonols showed no significant fragmentation under the conditions employed, but the flavanones and flavanols showed characteristic fragmentation which could be of use in structural elucidation of these compounds. |
