Abstract: 目的:建立奥美沙坦氢氯噻嗪片中奥美沙坦酯与氢氯噻嗪的测定方法.方法:采用高效液相色谱法,色谱柱为ODS-C18柱(250 mm ×4.6 mm,5 μm);流动相为0.03 mol·L-1磷酸二氢钾溶液(用磷酸调至pH3.6)-乙腈(50∶50),流速为1.0 mL·min-1;检测波长为271 nm.结果:奥美沙坦酯在7.89~71.03μg·mL-1范围内,峰面积与浓度呈良好的线性关系,r=0.999 9,平均回收率为99.7%(n=9);氢氯噻嗪在5.02~45.22μg·mL-1范围内,峰面积与浓度呈良好的线性关系,r=0.999 9,平均回收率为99.9%(n=9).结论:该方法可同时用于奥美沙坦氢氯噻嗪片中奥美沙坦酯与氢氯噻嗪的质量控制.
