脱氧雪腐镰刀菌烯醇-3-β-D-葡萄糖苷（D3 G）是真菌毒素脱氧雪腐镰刀菌烯醇（DON）的第二阶段植物代谢产物，存在于自然受镰刀菌污染的谷物中。为了研究D3 G在自然感染的谷物中的发生频率以及相对和绝对浓度，采用液相色谱-串联质谱法（LC-MS/MS）分析了来自奥地利、德国和斯洛伐克的23个小麦样品以及来自奥地利农田的54个玉米样品的DON和D3 G。这两种分析物在所有77个现场样品中均检出。DON被发现在42至4130 ng g-1（平均977 - 1000 ng g-1）的水平。所有谷物样品中的D3 G浓度在10-1070 ng g-1（平均216 - 253 ng g-1）的范围内，对应于约5-46摩尔%的DON浓度（平均15 - 8摩尔%）。
Deoxynivalenol-3--D-glucoside (D3G), a phase II plant metabolite of the mycotoxin deoxynivalenol (DON), occurs in naturally Fusarium-contaminated cereals. In order to investigate the frequency of occurrence as well as the relative and absolute concentrations of D3G in naturally infected cereals, 23 wheat samples originating from fields in Austria, Germany and Slovakia as well as 54 maize samples from Austrian fields were analysed for DON and D3G by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Both analytes were detected in all the 77 field samples. DON was found at levels from 42 to 4130 ng g-1 (977 1000 ng g-1 on average). The D3G concentrations in all cereal samples were in the range 10-1070 ng g-1 (216 253 ng g-1 on average), corresponding to about 5-46 mol% of their DON concentrations (15 8 mol% on average).
