Abstract
AbstractFumonisin (FB) mycotoxins are produced by Fusarium monoliforme, which grows primarily on yellow corn. Ingestion of FB1‐contaminated food causes leukoencephalomalacia in horses, pulmonary edema in pigs, and is suspected in the etiology of human esophageal cancer. Chromatographic separation and detection of underivatized fumonisins has been hampered because these compounds are nonvolatile, thermally labile, and devoid of chromophoric functional groups. We report here a simple liquid chromatography/mass spectrometry method employing chromatographic separation on a polymer‐based column coupled with sensitive detection using positive‐ion electrospray mass spectrometry for the quantification of fumonisins B1, B2 and B3 in extracts of commercial corn meal.
