脉君安颗粒质量标准研究
Qilu Pharmaceutical Affairs(2011)
Abstract
目的建立脉君安颗粒的质量标准控制方法.方法采用薄层色谱法对本品中的钩藤、葛根、氢氯噻嗪进行薄层鉴别;采用高效液相色谱法对本品中的葛根素、氢氯噻嗪进行含量测定.结果在薄层色谱图中,钩藤、葛根、氢氯噻嗪斑点清晰,无干扰;葛根素在0.096~1.92μg范围内呈良好的线性关系(r=0.999 7),平均回收率为99.04%,RSD=1.12%;氢氯噻嗪在0.136 2~1.362μg范围内呈良好的线性关系(r=0.999 7),平均回收率为100.09%,RSD=1.40%.结论所建立的方法可靠、准确、专属性强,可有效控制脉君安颗粒的质量.
