合成了 DON-3SS-吡喃葡萄糖苷，并通过 LC-MS/MS 进行了表征。进一步评估了化学合成中副产物的形成，并且根据它们不同的断裂行为，可以推测它们的结构。通过分析在花期用 DON 处理的麦穗，研究了这些物质在自然界中的存在情况。首次在小麦中检测到 DON-3-葡萄糖苷，强烈表明它也可能存在于自然污染的谷物中。
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.
