Methods to analyze trichothecenes should be fast, reliable and economical. The known methods can be divided into two categories: the 'instrumental methods' as gas chromatography (GC) and high performance liquid chromatography (HPLC) and the so called 'fast methods' like thin layer chromatography (TLC), enzyme-linked immunosorbant analyses (ELISA) and flow through immunoassays. The most frequently used instrumental methods for the determination of deoxynivalenol (DON), HT-2- and T2-toxin in cereals and cereal products are based on gas chromatography with electron capture detectors or mass spectrometric (MS) detectors. More than 70% of the literature published in the last decade focuses on these techniques. Recently, high performance liquid chromatography with fluorescence detection and with mass spectrometric detection have gained importance. Up to now, a method which is able to detect types A and B trichothecenes simultaneously with a sufficiently low limit of detection is lacking, even though methods are published which have at least the same clean up step.
分析单端孢霉烯族毒素的方法应快速、可靠且经济。已知方法可分为两类:“仪器分析法”,如气相色谱法(GC)和高效液相色谱法(HPLC),以及所谓的“快速方法”,如薄层色谱法(TLC)、酶联免疫吸附分析(ELISA)和流动免疫分析。测定谷物及谷物制品中脱氧雪腐镰刀菌烯醇(DON)、HT - 2毒素和T2毒素最常用的仪器分析法是基于带有电子捕获检测器或质谱(MS)检测器的气相色谱法。过去十年发表的文献中超过70%都聚焦于这些技术。最近,带有荧光检测和质谱检测的高效液相色谱法变得越来越重要。到目前为止,尽管已发表的方法至少有相同的净化步骤,但仍缺乏一种能够以足够低的检测限同时检测A类和B类单端孢霉烯族毒素的方法。
