Keyword:  解肌宁嗽口服液葛根素高效液相色谱法含量测定;
Abstract: 目的 为提升解肌宁嗽口服液质量标准,建立高效液相色谱法测定解肌宁嗽口服液中葛根素含量的方法 .方法采用高效液相色谱法.色谱柱为Agilent Zorbax Eclipse plus C18(4.6 mm×250 mm,5μm),流动相为甲醇-0.1%柠檬酸溶液(25:75,V/V),流速为1.0 mL·min-1,检测波长为250 nm,柱温为30℃,进样量为10μL.结果 葛根素的进样量在0.0368~0.3684μg范围内与相应峰面积呈良好的线性关系;精密度、稳定性、重复性试验的RSD均≤2.0%;平均加样回收率为100.0%,RSD为0.8%(n=6).结论 本法简便、快速、结果准确、重复性好,可用于解肌宁嗽口服液的质量控制.
