篇名: | HPLC法同时测定氯苯醇溶液中氯霉素和盐酸苯海拉明的含量 |
TITLE: | |
摘要: | 目的:建立同时测定氯苯醇溶液中氯霉素和盐酸苯海拉明含量的方法。方法:采用高效液相色谱法。色谱柱为Diamonsil C18,流动相为含0.01 mol/L庚烷磺酸钠的磷酸盐缓冲液-乙腈(66.5 ∶ 33.5,V/V),柱温为35 ℃,流速为1 ml/min,检测波长为盐酸苯海拉明258 nm、氯霉素277 nm,进样量为10 μl。结果:氯霉素、盐酸苯海拉明检测质量浓度线性范围分别为34.8~139.4 μg/ml(r=0.999 8)、93.0~930.5 μg/ml(r=0.999 8);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为97.70%~104.02%、96.72%~101.72%,RSD分别为2.2%、1.6%(n=9)。结论:该方法专属性强、结果准确、精密度好,适用于氯苯醇溶液的质量控制。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous contents determination of chloramphenicol and diphenhydramine hydrochloride in Chlorobenzene alcohol solution. METHODS: HPLC was performed on the column of Diamonsil C with mobile phase of phosphate buffer-acetonitrile (66.5 ∶ 33.5,V/V) containing 0.01 mol/L sodium heptane, column temperature was 35 ℃, flow rate was 1 ml/min, detection wavelength was 258 nm for diphenhydramine hydrochloride and 277 nm for chloramphenicol, the injection volume was 10 μl. RESULTS: The linear range was 34.8-139.4 μg/ml for chloramphenicol (r=0.999 8) and 93.0-930.5 μg/ml for diphenhydramine hydrochloride (r=0.999 8); RSDs of precision, stability and reproducibility tests were lower than 2.0%; recoveries were 97.70%-104.02% (RSD=2.2%,n=9) and 96.72%-101.72%(RSD=1.6%,n=9). CONCLUSIONS: The method is specific, accurate with good precision, and suitable for the quality control of Chlorobenzene alcohol solution. |
