E. Rodrigues et al., FRAGMENTATION OF SOME ZEARALENONES BY FAST-ATOM-BOMBARDMENT MASS-SPECTROMETRY, Rapid communications in mass spectrometry, 11(14), 1997, pp. 1515-1520
The positive-ion fast-atom bombardment (FAB) mass spectra of 23 zearal
enone derivatives have been obtained and structures for the ion fragme
nts were proposed. Careful analysis of the FAB spectra obtained for th
ese derivatives, accurate mass measurement and MS/MS experiments for z
earalenone, 3'-oxozearalenone and 7'-methanolzearalanone, have led to
a proposed fragmentation scheme for this series of compounds, This kno
wledge has been helpful in the identification of underivatized zearale
nones from crude Fusarium rice culture extracts. (C) 1997 by John Wile
