Dispositions and tissue residue of zearalenone and its metabolites α-zearalenol and β-zearalenol in broilers
Zearalenone (ZEA) is a secondary fungal metabolite produced mainly by a Fusarium graminearum. To clarify the toxicokinetics, and residues of ZEA and its major metabolites α-zearalenol (α-ZOL) and β-zearalenol (β-ZOL) in chickens, ZEA was then administered intravenously (iv) or orally (po) to broiler chickens at a dosage of 1.2 mg/kg body weight. The concentrations of ZEA, α-ZOL and β-ZOL in the...
متن کاملZearalenone and Its Derivatives α-Zearalenol and β-Zearalenol Decontamination by Saccharomyces cerevisiae Strains Isolated from Bovine Forage
Zearalenone (ZEA) and its derivatives are mycotoxins with estrogenic effects on mammals. The biotransformation for ZEA in animals involves the formation of two major metabolites, α- and β-zearalenol (α-ZOL and β-ZOL), which are subsequently conjugated with glucuronic acid. The capability of Saccharomyces cerevisiae strains isolated from silage to eliminate ZEA and its derivatives α-ZOL and β-ZO...
متن کاملLiquid chromatographic determination of alpha-zearalenol and zearalenone in corn: collaborative study.
The liquid chromatographic determination of alpha-zearalenol and zearalenone in corn was collaboratively studied. Each of 13 collaborators received 7 corn samples; 2 were blanks and 5 were spiked to contain 50, 100, and 200 ng alpha-zearalenol/g and 50, 100, 500, 1000, and 4000 ng zearalenone/g. Four sets (including blanks) of blind duplicates were included in the study. Five naturally contamin...
متن کاملBioactivation of zearalenone by porcine hepatic biotransformation.
Zearalenone (ZEA) is a resorcylic acid lactone derivative produced by various Fusarium species that are widely found in food and feeds. The structure of zearalenone is flexible enough to allow a conformation able to bind to mammalian oestrogen receptors, where it acts as an agonist. Using oestrogen-dependent Human Breast Cancer (MCF-7) cells, the oestrogenic activity of zearalenone and its deri...
متن کاملFusarium poae and Fusarium crookwellense, Fungi Responsible for the Natural Occurrence of Nivalenol in Hokkaido.
To determine the reasons for the natural occurrence of nivalenol in the northernmost area of Japan, scabby wheat was harvested from 19 crop fields in Hokkaido. Mycological surveys and analysis for mycotoxin contamination were performed. Among 13 wheat grain samples harvested in seven locations, 9, 2, and 6 samples were positive for deoxynivalenol, nivalenol, and zearalenone, respectively, at le...
