中文摘要: 建立核桃中黄曲霉毒素G1、G2、B1、B2、M1的测定方法。核桃经70%甲醇溶液提取、免疫亲和柱净化后，用高效液相色谱-串联三重四极杆质谱分析法测定。黄曲霉毒素 G1、G2、B1、B2、M1在 0.5 μg/L～50 μg/L 范围内与峰面积呈良好的线性关系，r＞0.999。回收率在86.5%～98.0%之间。此方法定量准确、专属性比较强，假阳性率低，有较普遍的实用性，适合核桃中黄曲霉毒素的测定。
Abstract:To establish the determination method of Aflatoxins G1，G2，B1，B2，M1in walnut.Walnut was extracted by 70%methanol solution，purified by immunoaffinity column and analyzed by ultra high performance liquid chromatography-tandem triple quadrupole mass spectrometry.The linear relationship between the peak area of Aflatoxins G1，G2，B1，B2，M1was 0.5 μg/L-50 μg/L，r＞ 0.999.The recoveries ranged from 86.5%to 98.0%.This method was accurate，and the specificity was relatively strong，the false positive rate was low，there were more general practicality，it was suitable for the determination ofAflatoxinsin walnut.
