| Objective To improve study quality standards of Chloramphenicol Metronidazole Cream. Methods The Chloramphenicol and Metronidazole were assayed by HPLC. In this method,the AgiLent XDB-C18(150mm×4.6mm,5um) was used at the rate of 1.0 mL/min and the column temperature of 30℃. 277 nm was selected as the detection wavelength for Chloramphenicol,the mobile phase was methanol- sodium heptanesulfonate (20:80)for Chloramphenicol.320 nm was selected as the detection wavelength for Metronidazole, the mobile phase was methanol-water for Chloramphenicol.Results A good linear relationship was established between the peak response and the concentration of Chloramphenicol and Metronidazole over the range of 5.56～111.2μg• mL−1(r=1.0000) and 26.02～260.2 μg.mL−1(r=0.9996) respectively. The mean recovery of Chloramphenicol and Metronidazole was 103.8 %(RSD=1.73%), and 99.6 % (RSD=0.43%) respectively． Conclusion The research will be pursuant of quality standard of Chloramphenicol Metronidazole Cream. |
