Abstract:
DON-3ß-glucopyranoside was synthesized and characterized by LC-MS/MS. The formation of by-products in the chemical synthesis was further evaluated and, according to their different fragmentation behaviours, it was possible to postulate their structures. The occurrence of these substances in nature was investigated by the analysis of wheat ears, which were treated with DON at anthesis. For the first time DON-3-glucoside could be detected in wheat, strongly indicating that it could also occur in naturally contaminated cereals.
