Abstract
- An ultrahigh-performance liquid chromatography–tandem mass spectrometry method was developed and validated for the simultaneous determination of sterigmatocystin, verruculogen, enniatin A, fusarenon-X, fumonisins B1, B2, B3, aflatoxins B1, B2, G1, G2, ochratoxin A, deoxynivalenol, 3-acetyldeoxynivalenol, 5-acetyldeoxynivalenol, and zearalenone. The mycotoxins were extracted and cleaned up using a multitoxin column, separated on a C18 column, and then detected on a triple-quadrupole mass spectrometer. The limits of detection and quantification ranged within 0.2–2 µg/kg and 1–10 µg/kg, respectively. The recoveries ranged from 70.8 to 118.4%, with relative standard deviations below 15%. The method was used to analyze 80 samples obtained from Shandong Province in China. Fifty-eight samples were contaminated with 10 mycotoxins at concentrations ranging from 1.4 to 6566.1 µg/kg. Some samples exceeded the maximum limits in China and in European regulations for mycotoxins in unprocessed maize. [ABSTRACT FROM PUBLISHER]
