ABSTRACT
To establish a method for the simultaneous determination of the active ingredients ( codeine phosphate, brompheniramine maleate, chlorpheniramine maleate, ephedrine hydrochloride and guaifenesin) in compound codeine phosphate oral preparations by capillary electrophoresis ( CE) . Methods:
The method employed an uncoated capillary column ( eCAPTM ) from Beck-mann company (50 cm × 75 μm);the electrophoresis voltage was at 10 kV;20 mmol·L-1 phosphate buffer solution (pH 7. 5) was used;the UV measurement was at the wavelength of 214 nm.Results:
The studied components had good linear ranges (r≥0. 995) within the range of the investigated concentrations. The recovery was no less than 96%.Conclusion:
The presented method can be ap-plied in the content determination of active ingredients in compound codeine phosphate oral preparations from different enterprises. It is simple, efficient and universal, which facilitates the market supervision in a fast and valid manner.
