摘要: 比较MycoSep?226多功能净化柱、DZT MS-PREP免疫亲和柱和实验室制备聚苯乙烯-二乙烯苯树脂免疫亲和柱在检测小麦粉中4 种镰刀菌毒素(玉米赤霉烯酮、脱氧雪腐镰刀菌烯醇、T-2毒素、HT-2毒素)过程中的前处理效果。选择MycoSep?226多功能净化柱、DZT MS-PREP免疫亲和柱和实验室制备聚苯乙烯-二乙烯苯树脂免疫亲和柱,通过不同的提取和前处理方法,以及建立高效液相色谱-串联质谱检测法,对小麦粉中的4 种镰刀菌毒素进行测定。DZT MS-PREP免疫亲和柱处理小麦粉样品所得的回收率为88.01%~107.31%,相对标准偏差为1.09%~14.42%;聚苯乙烯-二乙烯苯树脂免疫亲和柱的回收率为70.05%~112.80%,相对标准偏差为3.42%~12.25%;MycoSep?226多功能净化柱的回收率为69.42%~111.12%,相对标准偏差为1.46%~13.24%。免疫亲和柱具有重复利用,有机溶剂耗用量少、特异性强等显著优势,且聚苯乙烯-二乙烯苯树脂免疫亲和柱为新载体免疫亲和柱的制备提供了依据。

Abstract: A method for the simultaneous determination of four Fusarium toxins in wheat flour including zenralenone, deoxynivalenol, T-2 and HT-2 toxins was established using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Samples were cleaned up with a MycoSep?226 multifunctional column, a DZT MS-PREP immunoaffinity column, which were both commercial products, and a polystyrene-divinylbenzene (PS-DVB) immunoaffinity column which was prepared in our laboratory, respectively. The recoveries of Fusarium toxins purified with MycoSep?226 ranged from 69.42% to 111.12% with relative standard deviations (RSDs) of 1.46%–13.24%, those obtained with PS-DVB ranged from 70.05% to 112.80% with RSDs of 3.42%–12.25%, and those obtained with DZT MS-PREP ranged from 88.01% to 107.31% with RSDs of 1.09%–14.42%. Immunoaffinity columns had the advantages of repeated use, less organic solvent consumption and high specificity. Moreover, PS-DVB could be a promising new immunoaffinity carrier.

Key words: Fusarium toxins, high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), MycoSep?226 multifunctional column, polystyrene-divinylbenzene (PS-DVB) immunoaffinity column, DZT MS-PREP immunoaffinity column
