摘要:

建立了一种超高效液相色谱-串联质谱(UPLC-MS/MS)方法测定精油类化妆品中13种双酚类及烷基酚类环境激素。精油类化妆品以10%的氨水-乙腈溶液超声提取,氮吹浓缩后,以甲醇和水流动相梯度洗脱,经Agilent Poroshell EC-C18(3.0×150 mm,2.7 μm)色谱柱分离,电喷雾离子源负离子模式(ESI-)扫描,多反应监测模式(MRM)定量分析。结果表明,13种双酚类及烷基酚类环境激素在0.25~200 ng/mL中一定质量浓度范围内呈现良好线性关系,线性相关系数均大于0.99,各物质检出浓度(LOD)为0.000 375~0.007 5 µg/g,定量浓度(LOQ)为0.001 25~0.025 µg/g;在0.025,0.05及0.25 µg/g三种不同加标浓度水平下,各物质平均回收率范围为81.8%~113.4%,日内精密度(n=6)为1.1%~8.5%,日间精密度(n=18)为3.5%~11.5%,方法前处理过程简单、回收率好、稳定性高,实现了13种目标物质的有效色谱分离,适用于精油类化妆品中13种双酚类及烷基酚类环境激素的同时定量定性分析。

Abstract:

Environmental hormone is a kind of substance that can disturb biological endocrine, among which bisphenols and alkylphenols have great potential harm because they are widely used in the manufacture of plastics. At present, there are many researches on the related detection technologies in the fields of environment and food, but there are few reports on high-throughput simultaneous detection of bisphenols and alkylphenols in cosmetics. In order to analyze the migration amount of bisphenols and alkylphenols environmental hormones in cosmetics, an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 13 environmental hormones including 9 bisphenols and 4 alkylphenols in essential oil cosmetics. The chromatographic conditions, extraction reagent, dosage and ultrasonic time were optimized, then actual samples were measured with this established method. The essential oil cosmetics were extracted by ultrasonic extraction with 10% ammonium-acetonitrile solution, concentrated by nitrogen blowing, and eluted by gradient elution of methanol and water on an Agilent Poroshell EC-C18 column (3.0 mm×150 mm, 2.7 μm). The 13 analytes were scanned by electrospray ion source negative ion mode (ESI-), and analyzed with multiple response monitoring model (MRM). The results show that there is a good linear relationship for 13 kinds of bisphenols and alkylphenols environmental hormones in the certain mass concentration range of 0.25-200 ng/mL, with the linear correlation coefficients greater than 0.99. The limits of detection (LOD) and the limits of quantitation (LOQ) of each substance are 0.000 375-0.007 5 µg/g and 0.001 25-0.025 µg/g, respectively. The average recoveries at three spiked levels of 0.025, 0.05 and 0.25 µg/g range from 81.8% to 113.4% with the intra-day precision (n=6) of 1.1% to 8.5%, and the inter-day precision (n=18) of 3.5% to 11.5%. The method is established with simple pretreatment, good recovery and high stability, which has achieved effective chromatographic separation of 13 target substances. It is suitable for simultaneous quantitative and qualitative analysis of 13 bisphenols and alkylphenols environmental hormones in essential oil cosmetics.
