摘要:

采用高效液相色谱法(HPLC)建立同时测定化妆品中14种α-羟基酸和羟基酸酯含量的方法,并结合高效液相色谱-串联质谱联用法(HPLC-MS/MS)确证结果。采用高效液相色谱法,以0.05 mol/L的磷酸氢二铵水溶液和甲醇为流动相进行梯度洗脱,采用Waters T3-C18 (4.6×250 mm,5 µm)色谱柱分离,采用二极管阵列检测器检测,以214 nm为检测波长,外标法定量。采用高效液相色谱-串联质谱联用法,以0.1%甲酸水溶液和含0.1%甲酸乙腈为流动相进行梯度洗脱,采用Waters T3-C18 (2.1×100 mm,1.8 µm)色谱柱分离,电喷雾电离,正、负离子多反应监测模式定性。14种化合物在各自质量浓度范围内呈良好的线性关系,相关系数R2均大于0.999。4种基质样品,14种化合物平均加标回收率均在85%~115%范围内,相对标准偏差均小于5%,检出限为1~150 μg/g,定量限为3~450 μg/g。对7批含α-羟基酸和酯的样品进行液质确证,结果均为阳性。该方法操作简便、准确度好、灵敏度高,适用于化妆品中14种α-羟基酸及其酯的测定。

Abstract:

The study aimed to establish a method for simultaneous determination of 14 kinds of α-hydroxy acids and their esters in cosmetics by high performance liquid chromatography (HPLC),and the results were confirmed by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). HPLC was used for gradient elution with 0.05 mol/L diammonium hydrogen phosphate-methanol as the mobile phase. The analytes were separated on a Waters T3-C18 (4.6×250 mm, 5 µm) column and detected at the wavelengths of 214 nm. Quantification analysis was performed by the external standard method. HPLC-MS/MS was used for gradient elution with 0.1% formic acid-acetonitrile containing 0.1% formic acid as the mobile phase, and the analytes were separated on a Waters T3-C18 (2.1×100 mm, 1.8 µm) column. Qualitative analysis was performed by electronic spray ionization under a positive ion and negative ion mode with multiple reaction monitoring (MRM). The linearity of the 14 components in the concentration range is good, with the correlation coefficient r≥0.999. The average spiked recoveries of 14 compounds in 4 cosmetic matrices are all in the range of 85%-115%, and the relative standard deviations are all less than 5%. The limits of detections range from 1 μg/g to 150 μg/g. The limits of quantitation range from 3 μg/g to 450 μg/g. Seven batches of samples containing α-hydroxy acid and its ester were confirmed by HPLC-MS/MS and the results are positive. The results indicate that the method is simple, sensitive and accurate, and is suitable for the determination of 14 kinds of α-hydroxy acids and their esters in cosmetics.
