发布时间:2019-06-18 16:13
【摘要】:目的:建立同时测定复方地克软膏中氯霉素、克霉唑和醋酸地塞米松含量的方法。方法:采用高效液相色谱法。色谱柱为Thermo Hypersil BDS C18,流动相为甲醇-0.05 mol/L磷酸二氢钾(p H=5.7)(梯度洗脱),流速为1.0 ml/min,检测波长为235 nm,柱温为35℃,进样量为10μl。结果:氯霉素、克霉唑、醋酸地塞米松检测质量浓度分别在0.10~0.40、0.05~0.20、0.03~0.12 mg/ml范围内与峰面积呈良好的线性关系;精密度、稳定性、重复性试验的RSD2%;回收率分别为95.42%~103.28%、97.12%~102.96%、95.10%~102.69%,RSD分别为2.8%、1.8%、2.9%(n=9)。结论:该方法简便快速、结果准确、重复性好,适用于复方地克软膏及相关制剂的质量控制。
