摘 要: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。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 .
