【摘要】：目的:建立同时测定缬沙坦氢氯噻嗪片中缬沙坦和氢氯噻嗪含量的方法。方法:采用超高效液相色谱法。色谱柱为Phenomenex C_(18),流动相为[0.1%磷酸溶液-乙腈(95∶5,V/V)]-[0.1%磷酸溶液-乙腈(5∶95,V/V)](梯度洗脱),流速为0.25 mL/min,检测波长为272 nm,柱温为35℃,进样量为1.5μL。结果:缬沙坦和氢氯噻嗪检测质量浓度线性范围分别为8.1~324.2μg/mL(r=0.999 9)、1.2~50.1μg/mL(r=0.999 9);定量限分别为0.24、0.04 ng,检测限分别为0.06、0.01 ng;精密度、稳定性、重复性试验的RSD2.0%;加样回收率分别为97.69%~100.35%(RSD=1.03%,n=9)、98.27%~100.60%(RSD=0.83%,n=9)。结论:该方法操作简单、快速,结果准确,可用于缬沙坦氢氯噻嗪片中缬沙坦和氢氯噻嗪含量的同时测定。
