Preparation and Determination of Contents of Compound Ornidazole Gargle / 中国药房

ABSTRACT

OBJECTIVE:To prepare and establish the method for measuring the content of ornidazole gargle.METHODS:Maximal wavelength and dual-wavelength point spectrophotometries were used to determine the contents of ornidazole and chlorhexidine acetate respectively.RESULTS:The calibration curve of ornidazole and chlorhexidine acetate were linear in the range of5.5～16.6?g/ml and5.6～16.8?g/ml respectively.The average recovery rates of ornidazole and chlorhexidine acetate were100.23%and99.77%respectively,and their RSD were0.47%and0.31%respectively.CONCLUSION:The method of preparation and quality control is simple,quick and accurate.
