title: Analysis of Fusarium mycotoxins by gas chromatography--Fourier transform infrared spectroscopy.
abstract: The Fourier transform infrared (FTIR) spectra of selected Fusarium mycotoxins of various structure types were determined. Absorptions were observed for the following functionalities: hydroxyl at 3625-65 cm-1 and 3482 cm-1, the latter being associated with a 7 alpha-hydroxyl adjacent to an 8-carbonyl in keto trichothecenes; carbonyl at 1760-6 cm-1 for 5-membered rings and at 1695-8 cm-1 for those conjugated to a single C = C in a six-membered ring; acetate carbonyl at 1765 cm-1 and acetate C-O at 1220-9 cm-1; and C = C at 1680 cm-1. Gas chromatography combined with FTIR and mass spectrometry was applied to the identification of some mycotoxins in a F. roseum liquid culture extract.
