摘要
目的:建立HPLC法同时测定复方阿魏酸钠阿司匹林胶囊中阿魏酸钠、桂利嗪、阿司匹林、维生素B1的含量。方法:采用Synergi 4u Hydro-RP 80 A C18(250 mm×4.6 mm,5μm)色谱柱,以甲醇-乙腈-p H 2.8醋酸溶液为流动相,梯度洗脱,流速1.0 m L·min-1,检测波长270 nm,柱温25℃。结果:阿魏酸钠、桂利嗪、阿司匹林、维生素B1质量浓度分别在20.18-201.76、9.20-91.95、10.03-100.32、4.62-46.18μg·m L^-1范围内呈良好的线性关系(r≥0.9996);低、中、高浓度平均回收率(n=3),阿魏酸钠为100.4%(RSD=0.8%)、99.9%(RSD=0.5%)、101.2%(RSD=0.9%),桂利嗪为100.6%(RSD=0.8%)、98.6%(RSD=0.7%)、98.4%(RSD=0.8%),阿司匹林为100.2%(RSD=1.2%)、98.2%(RSD=1.0%)、96.0%(RSD=1.1%),维生素B1为99.7%(RSD=1.3%)、98.9%(RSD=1.1%)、96.7%(RSD=1.5%)。结论:本文方法简便、准确,适用于复方阿魏酸钠阿司匹林胶囊的质量评价。
Objective : To establish an HPLC method for four components ( sodium ferulate, cinnarizine, aspirin, vita- min B1 )in compound sodium ferulate and aspirin capsules. Methods: The separation was performed on Synergi 4u Hydro - RP 80 A C18 (250 mm ×4.6 mm,5 μm) column with the mobile phase of methanol - aeetonitrile - pH 2. 8 acetic acid water solution with gradient elution at the flow rate of 1.0 mL· min^- 1, and the detection wavelength was 270 nm and the column temperature was 25 ℃. Results:The linear ranges of sodium ferulate, cinnarizine, aspirin and vitamin B1 were 20. 18 -201.76 μg · mL^-1 (r =0. 9999) ,9.20 -91.95μg · mL^-1 (r =0. 9999) ,10. 03 - 100. 32 μg · mL^-1 ( r = 0. 9994) and 4.62 - 46. 18 μg · mL^-1 ( r = 0. 9993 ) , respectively. The average recoveries ( n = 3) of low, middle and high concentrations were 100.4% ( RSD = 0. 8% ) , 99.9% ( RSD = 0. 5% ) , 101.2% (RSD = 0.9% )for sodium ferulate; 100.6% (RSD = 0. 8% ) , 98.6% ( RSD =0. 7% ) , 98.4% (RSD = 0. 8% )for cinnarizine;100. 2% ( RSD = 1.2% ) ,98.2% ( RSD = 1.0% ) ,96. 0% ( RSD = 1.1% ) for aspirin; and 99.7% ( RSD = 1.3 % ) ,98.9 % ( RSD = 1.1% ), 96.7 % ( RSD = 1.5 % ) for vitamin B1. Conclusion: This method is simple, accurate, and suitable for the quality evaluation of compound sodium ferulate and aspirin capsules.
