摘要: | 目的:建立同时测定复方苯海拉明滴鼻液中盐酸麻黄碱、呋喃西林、盐酸苯海拉明含量的方法。方法:采用反向高效液相色谱法。色谱柱为Inertsil ODS-3 C18,流动相为0.05 mol/L磷酸二氢钾缓冲液(pH 7.0)-乙腈(梯度洗脱),流速为1.0 mL/min,检测波长为256 nm,柱温35 ℃,进样量为20 μL。结果:盐酸麻黄碱、呋喃西林、盐酸苯海拉明检测质量浓度线性范围分别为122.1~366.3 μg/mL(r=0.999 9)、5.2~15.5 μg/mL(r=0.999 8)、31.5~94.5 μg/mL(r=0.999 4);定量限分别为2.442、0.010、2.520 μg/mL,检测限分别为0.810、0.003、0.830 μg/mL;精密度、稳定性、重复性试验的RSD<1.0%;加样回收率分别为99.2%~101.7%(RSD=0.9%,n=9),96.4%~102.0%(RSD=1.7%,n=9),100.2%~101.9%(RSD=0.4%,n=9)。结论: 该方法操作简便、结果准确、重复性好,适用于复方苯海拉明滴鼻液中盐酸麻黄碱、呋喃西林、盐酸苯海拉明含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of ephedrine hydrochloride, nitrofural and diphenhydramine hydrochloride in Compound diphenhydramine nasal drop. METHODS: RP-HPLC method was adopted. The determination was performed on Inertsil ODS-3 C18 column with mobile phase consisted of 0.05 mol/L potassium dihydrogen phosphate buffer (pH 7.0)-acetonitrile (gradient elution) with flow rate of 1.0 mL/min. The detection wavelength was set at 256 nm, and the column temperature was 35 ℃. The sample size was 20 μL. RESULTS: The concentrations of phedrine hydrochloride, nitrofural and diphenhydramine hydrochloride ranged 122.1-366.3 μg/mL(r=0.999 9), 5.2-15.5 μg/mL(r=0.999 8)and 31.5-94.5 μg/mL(r=0.999 4), respectively. The limits of quantitation were 2.442, 0.010, 2.520 μg/mL, and the limits of detection were 0.810, 0.003, 0.830 μg/mL, respectively. RSDs of precision, stability and reproducibility tests were lower than 1.0%. The recoveries of them were 99.2%-101.7% (RSD=0.9%,n=9), 96.4%-102.0%% (RSD=1.7%,n=9), 100.2%-101.9%(RSD=0.4%,n=9), respectively. CONCLUSIONS: The method is simple, accurate and reproducible, and can be used for simultaneous determination of ephedrine hydrochloride, nitrofural and diphenhydramine hydrochloride in Compound diphenhydramine nasal drop. |
