高效液相色谱法同时测定化妆品中15种防晒剂
Simultaneous determination of 15 kinds of sun screener in cosmetics by HPLC
摘要
Abstract
HPLC method for determination of 15 kinds of sun screener used in cosmetics specified in Cosmetic Health Norm (2007 edition)was optimized and improved. The sample was extracted with a mixed solution composed of V(methanol)∶ V(tetrahydrofuran,THF)∶ V(water)∶ V(0. 067% perchloric acid)= 250∶ 450∶300∶ 0. 2 and separated with methanol - THF - 0. 067% perchloric acid as mobile phase with gradient elution on Kromasil C18 analytical column,at flow rate of 1 mL/ min,and detector wavelength of 311 nm. The method shows good linear relationship in conventionally proper mass concentration range;the spiked recoveries are between 85. 6% - 115. 9%;the detectable limit is within 0. 8 - 12. 5 ng.关键词
