摘　　要：优化高效色谱法测定防晒化妆品中紫外光吸收剂UV-360含量的方法。采用甲醇对化妆品进行萃取后进行分析测定,C18色谱柱(250mm×4.6 mm,5μm)、二极管阵列检测器(1.00m L/min)、检测波长为280nm,流动相为90%异丙醇。结果表明,紫外光吸收剂UV-360在0.001mg/L至0.012mg/L的浓度范围呈良好的线性关系,检出限为0.00106mg/L,回收率在100.8%,相对标准偏差(RSD)3.0%。该方法准确、可靠,可用于防晒化妆品中紫外光吸收剂UV-360的检测。An optimized HPLC method for the determination of UV-360 in sunscreen cosmetics.The cosmetics were extracted with methanol and analyzed with C18 column(2504.6 mm,5 m),diode array detector,1.00 Ml/min,detection wavelength:280 nm.The mobile phase is 90%ISOPROPANOL.Results the concentration range of UV-360 was linear from 0.001 to 0.012 mg/l,the detection limit was 0.00106 mg/1,the recovery was 100.8%,the relative standard deviation(RSD)was 3.0%.The method is accurate and reliable,and can be used for the determination of UV-360 in sunscreen cosmetics.
