摘要: 建立了高效液相色谱-串联质谱（HPLC-MS/MS）同时检测饲料中11种霉菌毒素的分析方法。样品经乙腈提取，MycoSep 228多功能净化柱填料和PRIME HLB固相萃取柱净化；采用Agilent Zorbax SB-C18色谱柱（150 mm×2.1 mm，3.5 μ m）分离，以甲醇和5 mmol/L乙酸铵水溶液（含0.1%（v/v）甲酸）为流动相梯度洗脱；采用ESI源正、负离子同时扫描，多反应监测（MRM）模式测定，内标法定量。结果表明，11种目标物在各自的线性范围内线性关系良好，相关系数均大于0.99，定量限为2.0~50.0 μ g/kg。11种霉菌毒素在3个加标水平（1、2、5倍定量限）下的平均回收率为79.3%~101.6%，相对标准偏差（RSD）为5.9%~13.2%（n=5）。该法简单快速，净化效果好，灵敏度高，适用于饲料中11种霉菌毒素的分析。

Abstract: A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the simultaneous determination of 11 mycotoxins in feeds. The samples were extracted with acetonitrile, then cleaned up by multifunctional purification column filler and PRIME HLB solid phase extraction column. The 11 mycotoxins were separated on an Agilent Zorbax SB-C18 column (150 mm×2.1 mm, 3.5 μ m) with gradient elution program, and methanol-5 mmol/L ammonium acetate solution containing 0.1%(v/v) formic acid were used as mobile phases. The target compounds were detected under electrospray ionization (ESI) both in positive and negative modes with multiple reaction monitoring mode, and quantified by internal standard method. The results indicated that the 11 mycotoxins showed good linear relationships in their respective linear ranges, and the correlation coefficients were greater than 0.99. The limits of quantification (LOQs) were between 2.0 and 50.0 μ g/kg. The average recoveries were between 79.3% and 101.6% at three spiked levels (1, 2 and 5 times LOQs) with relative standard deviations (RSDs) of 5.9%-13.2% (n=5). The method is simple, rapid, sensitive, and can be used for the analysis of the 11 mycotoxins in feeds.
