摘要:

建立了超高效液相色谱-三重四级杆质谱法(UPLC/MS-MS)测定人参化妆品中人参功效成分(人参皂苷Rg1,人参皂苷Re),并用该方法对市售28批样品进行风险监测。样品采用甲醇超声提取法,以0.05%甲酸水溶液-0.05%甲酸乙腈溶液为流动相,梯度洗脱,ACQUITY UPLC BEH C18 (2.1 mm×100 mm×1.7 μm)色谱柱分离,以UPLC/MS-MS负离子模式检测。同时对样品前处理条件及色谱-质谱条件进行优化,并完成方法学验证。结果表明,两种目标化合物在0.1~50 ng/mL及0.5~200 ng/mL质量浓度范围内呈良好线性关系,R2大于0.999 6;LOD为0.001 7~0.003 0 μg/g (S/N=3);在膏霜、乳液、洗护类基质中加标回收率为81.87%~94.45%,相对标准偏差小于5.64% (n=6)。该方法适用于人参化妆品中人参功效成分的测定。

Abstract:

A method was established for the determination of ginseng functional components (ginsenoside Rg1, ginsenoside Re) in ginseng cosmetics with ultra-high performance liquid chromatography triple quadrupole mass spectrometry (UPLC/MS-MS). This method was used to monitor the risk of 28 batches of samples sold on the market. The samples were extracted by methanol ultrasonic method. The mobile phase was 0.05% formic acid aqueous solution - 0.05% formic acid acetonitrile solution, and the gradient elution was carried out. The samples were separated on the ACQUITY UPLC BEH C18 (2.1 mm×100 mm×1.7 μm) column and detected by UPLC/MS-MS negative ion mode. At the same time, the pretreatment conditions and UPLC/MS-MS conditions were optimized and the method was verified. The results show that the method shows good linearity in the concentration range of 0.1-50 ng/mL and 0.5-200 ng/mL, with R2 no less than 0.999 6. The limits of detection are in the range of 0.001 7-0.003 0 μg/g (S/N=3) . The average recoveries in sample matrix of cream, lotion and shampoo are from 81.87% to 94.45%, with relative standard deviations (RSDs) less than 5.64 (n=6) . This method is suitable for the determination of ginseng functional components in ginseng cosmetics.
