摘要:

建立了超高效液相色谱-三重四极杆质谱法(UPLC-MS/MS)同时分离测定市售面膜中包括喹诺酮类、咪唑类及糖皮质激素等26种禁用成分。样品经饱和氯化钠溶液分散后乙腈提取,并利用亚铁氰化钾和乙酸锌沉淀大分子基质和固相萃取净化后,以0.1%醋酸乙腈-0.1%醋酸水溶液二元梯度洗脱,采用多反应监测进行分析。结果显示,26种化合物在各自浓度范围内线性关系良好,相关系数均不低于0.995,检出限为1~80 ng/g,定量限为4~380 ng/g,平均回收率为86.4%~115.2%。本法简单准确,灵敏度高,可用于市售面膜中禁用物质的定量分析。

Abstract:

An ultra performance liquid chromatography-triple quadrupole mass spectrometric (UPLC-MS/MS) method was developed for simultaneous separation and determination of 26 prohibited substances in commercially available masks, which contained glucocorticoid, quinolones and imidazole derivatives. The samples were dispersed in saturated sodium chloride solution and were extracted with acetonitrile. After removal of macromolecular matrix by potassium ferrocyanide and zinc acetate, the samples were purified by solid phase extraction. The binary gradient elution was performed with acetonitrile (containing 0.1% acetic acid)-0.1% acetic acid solution, and the multi-reaction monitoring was used for analysis. All the 26 compounds show a good linear relationship in their respective concentration ranges, and the correlation coefficients (r) are no less than 0.995. The limits of detection (LODs) range from 1 to 80 ng/g. The limits of quantification (LOQs) are in the range of 4-380 ng/g. The average recoveries of 26 prohibited substances in masks range from 86.4% to 115.2%. The method is simple, accurate and sensitive. It can be used for quantitative analysis of prohibited substances in commercially available masks.

Key words: ultra performance liquid chromatography-triple quadrupole mass spectrometry, mask, glucocorticoid, quinolones, imidazole derivatives
