介绍胃尔宁片质量标准的研究，采用薄层层析对其中党参、制马钱子、厚朴等成分进行化学鉴别试验及高效液相色谱法同时测定土的宁和马钱子碱的含量。方法简便、快速、准确，平均加样回收率（n＝5）士的宁为99．24％，马钱子碱为98.39％，变异系数分别为1．61％和1．80％。
The study on the quality standard of Weierning Tablets was introduced. The chemical identification test of Dangshen, Strychnos nudici, Magnolia officinalis and other ingredients was conducted by thin layer chromatography and the content of strychnine and strychnine was determined simultaneously by high performance liquid chromatography. . The method is simple, rapid and accurate. The average recovery rate (n=5) is 99.24% for strychnine, 98.39% for strychnine, and the coefficient of variation is 1.61% and 1.80%, respectively.
