摘要: | 目的:建立同时测定丁氯麻滴眼剂中氯霉素、盐酸麻黄碱、盐酸丁卡因含量的方法。方法:采用高效液相色谱-二极管阵列检测器多波长法。色谱柱为ZORBAX SB-C18,流动相为pH 3.0磷酸盐缓冲溶液-乙腈(梯度洗脱),柱温为室温,流速为1.0 ml/min,进样量为20 μl,检测波长为277 nm(氯霉素)、210 nm(盐酸麻黄碱)、310 nm(盐酸丁卡因)。结果:氯霉素、盐酸麻黄碱、盐酸丁卡因的检测质量浓度线性范围分别为12.56~125.6 μg/ml(r=0.999 8)、25.55~255.5 μg/ml(r=0.999 9)、25.25~252.5 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<2%;回收率分别为98.39%~100.44%(RSD=0.79%,n=9)、100.40~101.74%(RSD=0.66%,n=9)、98.83~100.67%(RSD=0.70%,n=9)。结论:该方法灵敏度高、定量准确、专属性强,可用于丁氯麻滴眼剂的质量控制。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of chloramphenicol, ephedrine hydrochloride and tetracaine hydrochloride in Dinglyuma eye drop. METHODS:HPLC-DAD at muliti-wavelength was performed on the column of ZORBAX SB-C18 with mobile phase of pH 3.0 Phosphate buffer-acetonitrile (gradient elution), column temperature was room temperature, flow rate was 1.0 ml/min, injection volume was 20 μl, and the detection wavelength was 277 nm for chloramphenicol, 210 nm for ephedrine hydrochloride and 310 nm for tetracaine hydrochloride. RESULTS: The linear range was 12.56-125.6 μg/ml for chloramphenicol(r=0.999 8),25.55-255.5 μg/ml(r=0.999 9) for ephedrine hydrochloride and 25.25-252.5 μg/ml for tetracaine hydrochloride (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 98.39-100.44%(RSD=0.79%, n=9),100.40-101.74%(RSD=0.66%,n=9) and 98.83-100.67%(RSD=0.70%,n=9). CONCLUSIONS: The method is sensitive, accurate and specific, and can be used for the quality control of Dinglyuma eye drop. |
