摘要: 目的:建立一种液质联用的分析方法,同时测定4种抗生素(阿莫西林、阿莫西林钠、克拉维酸钾、克拉维酸叔辛胺)中的黄曲霉毒素(AFT B1、AFT B2、AFT G1、AFT G2)。方法: 采用液质联用仪(LC-MS/MS)、C18色谱柱、MRM模式同时测定4种抗生素中的4种黄曲霉毒素。结果: AFT B1在0.025~2.5 ng·mL-1范围内线性关系良好;AFT B2\G1\G2在0.05~2.5 ng·mL-1范围内线性关系良好;在线性范围内,阿莫西林和阿莫西林钠中的AFT可以准确测定;克拉维酸钾和克拉维酸叔辛胺中的AFT B1/B2/G1/G2含量高于2.5 ng·kg-1时可以被检出。结论: 该方法可以适用于检测4种抗生素(阿莫西林、阿莫西林钠、克拉维酸钾、克拉维酸叔辛胺)中的黄曲霉毒素。

Abstract: Objective: LC-MSMS method was established to determine aflatoxins (AFT B1、AFT B2、AFT G1、AFT G2) in four antibiotics. Methods: LC-MSMS,C18 column and MRM mode were used to simultaneously determine aflatoxins in antibiotics. Results: The calibration curves of AFT B1 was linear in ranges of 0.025~2.5 ng·mL-1. The calibration curves of AFT B2/G1/G2 were linear in ranges of 0.05-2.5 ng·mL-1. In range of linear, the content of AFT in amoxicillin and amoxicillin sodium can be quantitative detected. When the content of AFT B1/B2/G1/G2 in potassium clavulanate and tert octylamine clavulanate is higher than 2.5 ng·kg-1, it can be observed. Conclusion: This method can be used to detect AFT in amoxicillin, amoxicillin sodium, potassium clavulanate and tert octylamine clavulanate.
