【摘要】 目的:制订胃舒散质量标准。方法:采用薄层色谱法(TLC)鉴别三七、甘草,高效液相色谱法(HPLC)测定甘草酸铵的含量。结果:TLC色谱能明显检出三七、甘草,HPLC法对甘草酸铵含量测定线性关系良好,回归方程Y=805683.982X+7559.569,r=0.9997,甘草酸铵的平均回收率为99.23%,RSD=0.52%。结论:本方法简便,准确,重现性好,可供本品质量控制。更多还原

【Abstract】 Objective:To establish a quality standard for Wei Shu San.Methods:TLC was used to differentiate Radix Notoginseng and Radix Glycyrrhizae.The content of glycyrrhizinate in Wei Shu San was determined by HPLC.Results:TLC could obviously detect Notoginseng and Glycyrrhizae.The content of glycyrrhizinate showed a good linear relation.Regression equation was Y=805683.982X+7559.569,r=0.9997.The average recovery rate of the ammonium glycyrrhizinate was 99.23%,RSD was 0.52%.Conclusion:The method is simple and accurate with a good reappearance and can be used for the quality control of the granules.更多还原
