【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 C_18,流动相为0.05 mol/L磷酸二氢钾缓冲液(p H 7.0)-乙腈(梯度洗脱),流速为1.0 m L/min,检测波长为256 nm,柱温35℃,进样量为20μL。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122.1~366.3μg/m L(r=0.999 9)、5.2~15.5μg/m L(r=0.999 8)、31.5~94.5μg/m L(r=0.999 4);定量限分别为2.442、0.010、2.520μg/m L,检测限分别为0.810、0.003、0.830μg/m L;精密度、稳定性、重复性试验的RSD1.0%;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]:Aim: to establish a method for simultaneous determination of ephedrine hydrochloride, furacillin and diphenhydramine hydrochloride in compound diphenhydramine nasal drops. Methods: reverse high performance liquid chromatography (RP-HPLC) was used. The mobile phase consisted of 0.05 mol/L potassium dihydrogen phosphate buffer (p H 7.0)-acetonitrile (gradient elution), the flow rate was 1.0ml / min, the detection wavelength was 256nm, column temperature at 35 鈩，
