Abstract

Trichothecenes are the mycotoxins produced by different Fusarium species. Some of them, such as deoxynivalenol (DON), nivalenol (NIV), diacetoxiscyrpenol (DAS), toxins T-2 (T2) and HT-2 (HT2), are natural contaminants of wheat and corn. Extraction, clean-up and derivatization steps were evaluated and optimized for simultaneous determination of DON, NIV, DAS, HT2 and T2 in corn and corn products samples by gas chromatography-mass spectrometry (GC/MS). Extraction with acetonitrile : water (84:16) followed by clean-up through MycoSep 227 column presented the best results for the five toxins analysed. Trifluoroacetic anhydride / sodium bicarbonate derivatization showed better detection and quantification for the trichothecenes studied by GC/MS. The recoveries ranged from 83.3 to 113.3% for DON, 84.6 to 114.5% for NIV, 52.1 to 122.7% for DAS, 71.1 to 95.9% for T2 and from 81.8 to 155.4% for HT2. The detection limits ranged from 20 to 50 ng/g for DON, from 10 to 40 ng/g for NIV, from 30 to 120 ng/g for DAS, from 20 to 100 ng/g for T2 and from 20 to 50 ng/g for HT2. The repeatability of the method had relative standard deviations ranging from 4.5 to 18.1 for DON, 2.5 to 15.4 for NIV, 3.4 to 48.1 for DAS, 3.1 to 14.4 for HT2 and from 6.4 to 47.3 for T2.
