摘要: | 目的:建立同时测定复方氯霉素滴眼液中氯霉素、醋酸泼尼松龙及其降解产物氯霉素二醇物含量的方法。方法:采用高效液相色谱法。色谱柱为Dionex Acclaim C18,流动相为0.1%庚烷磺酸钠溶液-冰乙酸-乙腈-甲醇(60 ∶ 0.2 ∶ 30 ∶ 10,V/V/V/V),流速为1.0 mL/min,检测波长为271 nm,柱温为30 ℃,进样量为10 μL。结果:氯霉素、醋酸泼尼松龙、氯霉素二醇物检测质量浓度线性范围分别为11.73~703.71 μg/mL(r=0.999 8)、12.40~744.06 μg/mL(r=0.999 8)、1.03~62.03 μg/mL(r=0.999 8);氯霉素二醇物的定量限为0.01 μg/mL;精密度、稳定性试验的RSD<2.0%;氯霉素、醋酸泼尼松龙重复性试验的RSD<2.0%,氯霉素二醇物的RSD=4.5%;回收率分别为100.6%~102.7%(RSD=0.60%,n=9)、97.5%~100.3%(RSD=0.80%,n=9)、100.0%~103.2%(RSD=1.10%,n=9)。结论:该方法结果准确、操作简便,可用于复方氯霉素滴眼液中氯霉素、醋酸泼尼松龙及其降解产物氯霉素二醇物含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of chloramphenicol, prednisolone acetate and chloramphenicol glycols in Compound chloramphenicol eye drop. METHODS: HPLC was performed on the column of Dionex Acclaim C18 with mobile phase of 0.1% Heptane sodium sulfonate solution-glacial acetic acid-acetonitrile-methanol (60 ∶ 0.2 ∶ 30 ∶ 10,V/V/V/V) at a flow rate of 1.0 mL/min, detection wavelength was 271 nm, column temperature was 30 ℃, and the injection volume was 10 μL. RESULTS: The linear range was 11.73-703.71 μg/mL for chloramphenicol (r=0.999 8), 12.40-744.06 μg/mL for prednisolone acetate (r=0.999 8) and 1.03-62.03 μg/mL for chloramphenicol glycols (r=0.999 8); limit of quantification of chloramphenicol glycols was 0.01 μg/mL; RSDs of precision and stability tests were lower than 2.0%; RSDs of reproducibility test for chloramphenicol and prednisolone acetate were lower than 2.0%, RSD of chloramphenicol glycols was 4.5%; recoveries were 100.6%-102.7%(RSD=0.60%,n=9), 97.5%-100.3% (RSD=0.80%,n=9), 100.0%-103.2% (RSD=1.10%,n=9), respectively. CONCLUSIONS: The method is accurate, simple, and can be used for the simultaneous determination of chloramphenicol, prednisolone acetate and chloramphenicol glycols in Compound chloramphenicol eye drop. |
