The method of ultra high performance liquid chromatography with C18 solid extract column for determining zearalenone in corn was estabished .The sample was extracted with methylalcohol‐water(v/v=80∶20) ,purified by C18 solid extract column ,and the purify fluid was analyzed by ultra high performance liquid chromatography containing a fluoroscope . The detection limit of this method was 1 μg/kg ,recovery rate was 89% ~93% ,precision was 1 .0% ~2 .1% .This method had the advantages of simplicity ,sensitivity and good reproducibility .
