摘要: 试验旨在建立牛奶中6种玉米赤霉烯酮类霉菌毒素残留的超高效液相―串联质谱检测方法。牛奶样品经乙腈提取,免疫亲和柱净化,C18色谱柱分离,以0.02%(V/V)乙酸―水/甲醇为流动相,采用梯度洗脱方式进行液相色谱分离,多反应监测模式,外标法进行定量。牛奶中6种玉米赤霉烯酮类霉菌毒素的检测限可达到1.0 μg/L,且在2.5~100.0 μg/L的浓度范围内,线性关系良好。该方法专属性强、灵敏度高、分离度好,适用于牛奶中的6种玉米赤霉烯酮类霉菌毒素残留的测定。

Abstract: Developing a method for determination on 6 kinds of corn gibberellic olefine ketone (α-zearalanol, β-zearalanol, α-zearalenol, β-zearalenol, zearalanone and zearalenone) in the milk. The milk was concentrated after extracted with acetonitrile and purified by immunoaffinity solid-phase extraction and then was determined on an ACQUITY UPLCTM BEH C18 column with gradient elution using methanol and water (containing 0.02% acetic acid) as mobile phases. The mass spectrometric acquisitions were carried out by means of multiple reaction monitoring (MRM) in electrospray negative ionization mode. The detection limits were 1.0 μg/L for 6 kinds of corn gibberellic olefine ketone. The calibration curves were linear from 2.5~100.0 μg/L. This method was specific, sensitive, and suitable for determination on 6 kinds of corn gibberellic olefine ketone in the milk.

Key words: corn gibberellic olefine ketone; ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS); cow milk
