摘要: 建立了高效液相色谱-二极管阵列检测器(HPLC-DAD)同时测定化妆品中维生素C磷酸酯镁、维生素C、β-熊果苷、曲酸、氢醌、烟酰胺、4-甲氧基水杨酸钾和苯酚8种美白成分的方法。样品用甲醇提取,采用ODS-2 HYPERSIL色谱柱(250 mm×4.6 mm,5 μm)分离,以甲醇-0.02 mol·L-1磷酸二氢钾溶液为流动相梯度洗脱。结果表明,8种美白成分在2~500 mg·L-1内呈良好的线性关系,相关系数(r)均不低于0.998,方法检出限为0.3~1.0 ng,回收率为91.1%~105.0%,相对标准偏差(RSD)为0.12%~3.20%。

Abstract: An analytical method for determination of eight kinds of whitening ingredients [vitamin C magnesium phosphate,vitamin C,β-arbutin,kojic acid,hydroquinone,nicotinamide,potassium 4-methoxy salicylate and phenol] in cosmetics by using high performance liquid chromatography-diode array detector (HPLC-DAD) was established.The sample was extracted with methanol and separation was performed on column ODS-2 HYPERSIL (250 mm×4.6 mm,5 μm).Mobile phase for gradient elution was methanol-potassium dihydrogen phosphate solution with concentration of 0.02 mol·L-1.The detection results show good linearity within the range of 2-500 mg·L-1 with the correlation coefficients more than 0.998.The detection limits are in the range of 0.3-1.0 ng.The recoveries are between 91.1% and 105.0% with the relative standard deviations (RSD) of 0.12% to 3.20%.
