| Abstract: | Deoxynivalenol (DON)-glucosides were successfully synthesized in a two-step reaction from 1-β-Bromo-1-deoxy-2,3,4,6-tetra-O-acetyl-α-D-gluco-pyranose and 3-Acetyl-DON or 15-Acetyl-DON. After purification of the reaction products, the mycotoxin conjugates
were for the first time characterized by means of a triple quadrupole mass spectrometer in combination with a linear ion trap.
Due to different fragmentation behaviour it was also possible to distinguish between the two glucosides.
