摘要:

建立了美白类化妆品中氨甲环酸的高效液相色谱测定方法。采用5%甲醇溶液对化妆品样品中的氨甲环酸进行提取。样品用Shiseido CAPCELL PAK C18 UG120 色谱柱(4.6 mm×250 mm,5 μm)分离,以甲醇与0.05 mol/L KH2PO4-0.2% H3PO4溶液(体积比为5:95)为流动相,流速为1.0 mL/min,检测波长为210 nm。结果表明,氨甲环酸在5~100 mg/L范围内线性关系良好,相关系数(r)大于0.999。在各化妆品基质中方法检出限为10.7~22.2 μg/g,方法定量限为28.9~48.0 μg/g。回收率为95.23%~110.40%,RSD值为1.24%~3.59%(n=6)。日内稳定性良好,在24 h内峰面积RSD值为0.026%。该方法简便、可靠,可作为美白类化妆品中氨甲环酸的含量测定方法。

Abstract:

A high performance liquid chromatography (HPLC) method for the determination of tranexamic acid in whitening cosmetics was established. The tranexamic acid in cosmetic samples was extracted directly with 5% methanol solution. The separation was performed on a Shiseido CAPCELL PAK C18 UG120 column (4.6 mm×250 mm×5 μm), with the mobile phase of methanol and 0.05 mol/L KH2PO4-0.2% H3PO4 solution. The flow rate was 1.0 mL/min and detection wavelength was 210 nm. The detection results show good linearity within the range of 5-100 mg/L (r>0.999). The limit of detection (LOD) is 10.7-22.2 μg/g and the limit of quantitation (LOQ) is 28.9-48.0 μg/g in the cosmetics matrix. The recoveries range from 95.23% to 110.40%, and the RSD range is 1.24%-3.59%(n=6). The intraday stability is good, and the peak area RSD value is 0.026% within 24 h. The method is simple and reliable, and can be used for the determination of tranexamic acid in whitening cosmetics.
