| Abstract: | Objective To establish an HPLC method for the stimutaneous determination of chloramphenicol and dexamethasone sodium phosphate in lufuye. Methods The determination was performed on an Inertsil C8-3 column under 40 ℃; the mobile phase consisted of methanol-acetonitrile-water (72∶3∶25) with a flow rate at 1.0 mL·min-1. Detecting wavelength was set at 240 nm. Results The linear ranges for chloramphenicol and dexamethasone sodium phosphate were 62.1-745.2(r=0.999 9)and 6.22-74.64 mg·L-1 (r=0.999 9),respectively. The average recoveries were 101.02% (RSD=2.0%) and 100.05% (RSD=1.6%) Conclusion This method is rapid,simple and accurate and suitable for the determination of the content chloramphenicol and dexamethasone sodium phosphate in lufuye. |
