【Abstract】 Objective To establish a HPLC method for simultaneous determination of paracetamol, aminopyrine and caffeine in Anlinfenka capsules. Methods The Diamonsil C18(200 mm×4. 6 mm, 5μm) was used, the mobile phase was 1% acetic acid (adjust pH to 3.7 for diethylamine)-methand (6 : 4) . The detection wavelength was 272 nm with 30℃of column temperature. Results The linear range of paracetamol, aminopyrine and caffeine was 59. 448 - 138. 712μg/mL,75. 368 - 150. 736μg/mL,and 23. 340 -54. 460μg/mL respectiv... 更多还原 【关键词】 高效液相色谱法; 对乙酰氨基酚; 氨基比林; 咖啡因; 氨林酚咖胶囊; 【Key words】 HPLC; paracetamol; aminophenazone; caffeine; Anlinfenka capsules;
