摘要
目的:建立高效液相色谱法测定苯甲酸苄酯乳膏中苯甲酸苄酯的含量。方法:采用岛津C18色谱柱(4.6mm×150mm,5μm),以甲醇-水-乙腈(70:20:10,v/v)为流动相,流速1.2mL·min。紫外检测器于230nm测定。结果:线性范围13.186-92.302mg·L^-1 r=1.000,样品溶液在24h内稳定,平均回收率分别为100.2%。RSD为0.44%(n=9)。结论:本法简便、快速,结果准确、可靠,重复性好。
OBJECTIVE To Determine the content of benzyl benzoate in benzyl benzoate cream by HPLC. METHODS The column: Hypersil C18 column(4. 6 mm× 150 mm, 5 μm); The mobile phase: methanol-water-acetonitrile (70:20: 10, v/v) ;The flow rate: 1.2 mL. min^-1 ;The detection wavelength: 230 nm. RESULTS The linear response range was 13. 186- 92.302 mg . L^- 1 (r = 1. 0000) ; The sample solution is stable within 24 h. The average recovery was 100. 2 %, RSD was 0. 44% ( n = 9 ). CONCLUSION This method is simple .rapid ,accurate and reliable.
