Abstract
Naturally contaminated and artificiallyFusarium spp. inoculated wheat was analyzed for deoxynivalenol, deoxynivalenol-3-glucoside, 3-acetyl-deoxynivalenol and 15-acetyl-deoxynivalenol. After extraction and clean-up with MycoSep columns, the trichothecenes were determined using a LC-ESI-MS/MS method. Deoxynivalenol-3-glucoside was detectable in 4 out of 4 artificially inoculated and in 22 out of 25 naturally contaminated wheat samples. For the latter, the average relative deoxynivalenol-3-glucoside concentration was about 6% of the deoxynivalenol concentration. The maximum relative deoxynivalenol-3-glucoside concentration was 12% as compared to the concentration of deoxynivalenol. In all samples, the concentration of deoxynivalenol-3-glucoside was higher than the concentrations of 3-acetyl-deoxynivalenol or 15-acetyl-deoxynivalenol.
