摘要: 研究了单克隆免疫亲和柱——高效液相色谱法测定小麦中DON毒素的方法。样品通过聚乙二醇一水提取,提取液用DON毒素单克隆免疫亲和柱净化,Symmetry C18色谱柱分离,紫外检测器检测和外标法定量。该方法对添加不同含量DON毒素的平均回收率为86.11%~95.24%,变异系数(Cy)为0.88%~2.59%,最低检出限为0.1mg/kg,可用于小麦样品中DON毒素的检测。

Abstract: A method for determination of deoxynivalenol (DON) in wheat by high performance liquid chromatography (HPLC) is reported. The sample was extracted with PEG8000-water. Filtrate was cleaned up by DON test HPLC affinity cartridges. The DON was separated on Symmetry C18 column, detected by UV-detector and quantified by external standard. Wheat seeds samples were fortified with DON at different levels. This procedure could contribute to a DON recoveries of 86.11%-95.24 %, variation coefficients of 0.88 %-2.59 % and detection limit of 0.1mg/kg.
