摘要:

建立了采用高效液相色谱-串联质谱(HPLC-MS/MS)同时测定粉剂、片剂和胶囊剂等保健食品中12种双酚类化合物的检测方法。样品中双酚类化合物经1%(v/v)乙酸乙腈溶液提取,QuEChERS方法净化;12种化合物经Thermo Aquasil C18色谱柱(150 mm×4.6 mm,3.0 μm)分离后,分别在串联质谱正、负离子多反应监测(MRM)模式下检测,基质匹配外标法定量。研究结果表明,在0.5~50.0 μg/kg内,12种双酚类化合物的线性相关系数均大于0.99,方法的检出限(S/N>3)为0.1~0.5 μg/kg,定量限(S/N>10)为0.4~1.7 μg/kg,不同基质的保健食品在3个添加水平(2.0、5.0和10.0 μg/kg)下的回收率为60.5%~116.3%(n=6),相对标准偏差(RSD)为6.8%~11.2%(n=6)。方法操作简单、耗时短、灵敏度高,满足现行法规要求,可实现保健食品中双酚类化合物的定性和定量测定。

Abstract:

A method based on high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) for the simultaneous determination of 12 bisphenol substances in functional foods (powder, tablet, capsule) was presented. The samples were extracted by acetonitrile containing 1% (v/v) acetic acid followed by further cleaned up using matrix solid-phase dispersion to remove matrix interferences. The separation of the 12 bisphenol substances was performed on a Thermo Aquasil C18 column (150 mm×4.6 mm, 3.0 μm), and determined in the positive and negative MRM modes by MS/MS using matrix-matched external standard method. The results demonstrated that the calibration curves were of good linearity with the correlation coefficients greater than 0.99. The limits of detection (LODs, S/N>3) were in the range of 0.1-0.5 μg/kg and the limits of quantitation (LOQs, S/N>10) were 0.4-1.7 μg/kg. The recoveries of the 12 bisphenol substances spiked at three levels (2.0, 5.0 and 10.0 μg/kg) in matrix ranged from 60.5% to 116.3% with the relative standard deviations (RSDs) of 6.8% to 11.2%. The established method is simple, time-saving and sensitive. It can meet the requirements for current regulations while achieving qualitative and quantitative determination of the 12 bisphenol substances in functional foods.
