HPLC法同时测定鼻可灵喷雾剂中3组分的含量

目的:建立以高效液相色谱法同时测定鼻可灵喷雾剂中3组分含量的方法。方法:色谱柱为Hypersil ODS,流动相为0.1%三乙胺(磷酸调pH至3.2)-乙腈(75∶25),流速为1mL·min-1,检测波长为256nm,进样量为10μL。结果:氧氟沙星、盐酸麻黄碱、地塞米松磷酸钠检测浓度的线性范围分别为32~320(r=0.9999)、64~640(r=1.0000)、4~40(r=1.0000)μg·mL-1;平均回收率分别为100.05%、100.17%、99.85%,RSD分别为0.32%、0.48%、1.67%。结论:本方法简便、准确,可用于该制剂的质量控制。

Determination of 3 Kinds of Components in Bikeling Nasal Spray by HPLC

OBJECTIVE:To establish a HPLC method for the simultaneously determination of three components in Bikeling nasal spray. METHODS: The column we used was Hypersil ODS and the mobile phase was 0.1%mtriethylamine(adjust pH3.2 with phosphate acid)-acetonitrile (75∶25). The detective wavelength was 256nm and the sample size was 10μL. RESULTS: The linear rangs of ofloxacin, ephedrine hydrochloride and dexamethasone sodium phosphate were 32～320μg·mL-1(r=0.999 9),64～640μg·mL-1(r=1.000 0) and 4～40μg·mL-1(r=1.000 0)respectively, and the average recoveries were 100.05%(RSD=0.32%), 100.17%(RSD=0.48%) and 99.85%(RSD=1.67%),respectively. CONCLUSION: The method was simple and accurate and can be used for the quality control of Bikeling nasal spray
