摘 要:目的:建立HPLC法同时测定硝苯地平氢氯噻嗪片中硝苯地平、氢氯噻嗪含量的方法。方法色谱柱为 DIONEX Acclaim 120 C18柱(4.6mm×250mm,5μm),流动相为0.1mol? L -1磷酸二氢钠(用磷酸调节pH值至3.0±0.1)-乙腈梯度洗脱,流速:1.0mL·min -1,柱温:30℃;检测波长为230nm。结果硝苯地平、氢氯噻嗪的线性范围分别为4.01~64.16μg? mL -1(r=1.0000)、8.04~128.70μg? mL -1(r=0.9999),平均回收率分别为99.82%( RSD=0.89%),99.53%( RSD=0.97%)。结论建立的方法准确、可靠,简单易行,适用于硝苯地平氢氯噻嗪片中硝苯地平、氢氯噻嗪的质量控制。OBJECTIVE To establish a method for determination of nifedipine,hydrochlorothiazide in nifedip-ine Hydrochlorothiazide Tablets.METHODS The chromatographic column was DIONEX Acclaim 120 C18 column (4.6mm ×250mm,5μm) ,the mobile phase was 0.1mol? L-1 sodium dihydrogen phosphate ( value to 3.0 ±0.1 with phosphoric acid to regulate pH ) acetonitrile gradient elution, flowrate:1.0 mL·min-1 , column temperature:30℃;the detection wavelength was 230 nm.RESULTS The linear range for nifedipine and hydrochlorothiazide were 4.01~64.16μg? mL-1(r=1.0000) and 8.04~128.70μg? mL-1(r=0.9999),the average recovery rate were 99.82%(RSD=0.89%) and 99.53%(RSD=0.97%).CONCLUSION The methodis accurate,reliable,sim-ple,and suitable for the quality control of nifedipine,hydrochlorothiazide in nifedipine Hydrochlorothiazide Tablets.
