| Abstract: | A rapid method for the simultaneous determination of diphenoxylate and atropine by capillary electrophoresis with high frequency conductivity detection was described. The key factors for separation and determination were studied and the best analysis conditions were obtained, in the buffer solution of 10.0 mmol/L lactic acid-15.0?H5OH at the separation voltage of 20.0 kV, the diphenoxylate and atropine could be separated and detected within 6 min. Diphenoxylate and atropine showed good linear response in the range of 5.0-500 mg/L and 2.0-320 mg/L, and the limit of detection was 3.0 and 1.0 mg/L, respectively. The method was used for the determination of diphenoxylate and atropine in diphenoxylate hydrochloride and atropine sulfate tablets satisfactorily. |
