摘要: 建立了检测油脂及油炸食品中7种杂环胺类物质的超高效液相色谱-三重四极杆质谱（UPLC-MS/MS）的检测方法。以含1%（体积分数）氨水的乙腈溶液为提取液，采用乙腈饱和的正己烷脱脂，以PCX固相萃取柱为净化柱，10 mmol/L甲酸铵溶液（pH 6.8）和乙腈为流动相，采用Waters ACQUITY UPLC BEH C18反相色谱柱（50 mm×2.1 mm，1.7 μ m）梯度洗脱，流速为0.3 mL/min，在正离子扫描、多反应监测模式下测定，内标法定量。结果表明，杂环胺类物质在各自范围内，线性关系良好，相关系数大于0.999；在3个加标水平下，杂环胺类物质在油脂和油炸食品中的平均回收率为64.31%~113.8%，相对标准偏差为0.18%~9.26%，检出限（S/N=3）和定量限（S/N=10）分别为0.01~0.14 ng/g和0.09~0.38 ng/g。该方法具有灵敏、准确等优点，适用于油脂和油炸食品中杂环胺的确证检测。

Abstract: An ultra performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS) method was developed for the determination of seven heterocyclic aromatic amines (HCAs) in oil and fried food samples. The samples were extracted with acetonitrile containing 1% (v/v) ammonia water, defatted by n-hexane saturated with acetonitrile, and cleaned up with PCX solid phase extraction column. The extracts were separated on a Waters ACQUITY UPLC BEH C18 reversed-phase column (50 mm×2.1 mm, 1.7 μ m) with gradient elution by using acetonitrile-10 mmol/L ammonium formate aqueous solution as the mobile phase. Quantitative detection was performed by using a positive-ion electrospray ionization source in the multiple reaction monitoring (MRM) mode, employing an internal isotope standard. The method showed good linear relationships in the range of 0.5-100 μ g/L for the seven HCAs with correlation coefficients (R²)>0.999. The average recoveries ranged from 64.31% to 113.8% with the relative standard deviations of 0.18%-9.26% at the three spiked levels in oil and fried food samples. The limits of detection (LODs) and limits of quantification (LOQs) were 0.01-0.14 ng/g and 0.09-0.38 ng/g, respectively. The method is sensitive, accurate, and suitable for the determination and confirmation of the seven HCAs in oil and fried food samples.
