生津颗粒质量控制研究

目的 为控制生津颗粒的质量，建立了地黄、麦冬的薄层鉴别和甘草酸的含量测定。方法 采用薄层色谱法对样品中地黄和麦冬进行定性鉴别，用HPLC法测定甘草酸含量。结果 鉴别方法专属性强，定量方法简便、可靠。平均回收率为99．42％，RSD为1．54％。结论 此标准可有效地控制本品的质量。

Study on the quality control of shengjin granuces

AIM To establish TLC identification method of radix rehmanniae and prodix ophiopogons and the quanitutive determination of glycyrrhizic acid in shengjin granuces preparation. METHODS The sample was identified by TLC in contrast with radix rehmanniae and radix ophiopogons, and glycyrrhizic acid content was determinated by HPLC. RESULTS The method was highly specific and spots was concentrated. The average recovery was 99 42% and RSD was 1 54%. CONCLUSION As a result, identification was simple and accurate, and available for quality control of this preparation.
