The positive‐ion fast‐atom bombardment (FAB) mass spectra of 23 zearalenone derivatives have been obtained and structures for the ion fragments were proposed. Careful analysis of the FAB spectra obtained for these derivatives, accurate mass measurement and MS/MS experiments for zearalenone, 3′‐oxozearalenone and 7′‐methanolzearalanone, have led to a proposed fragmentation scheme for this series of compounds. This knowledge has been helpful in the identification of underivatized zearalenones from crude Fusarium rice culture extracts. © 1997 John Wiley & Sons, Ltd.
