摘要

This is the first report of a metabolic conversion in animals of zearalenone to zearalanols. Zearalenone was labeled with deuterium by base-catalyzed isotope exchange. The labeled zearalenone, in the form of its beta-cyclodextrin inclusion complex, was administered orally and intravenously to sheep. In addition to deuteriozearalenone glucuronide, analysis of the urine revealed the presence of deuteriated alpha- and beta-zearalenol and alpha- and beta-zearalanol glucuronides. No zearalanone was detected in the urine. The problem of cis-trans isomerization of zearalenone in the presence of sunlight is also discussed.
