复方通肠颗粒的质量标准研究

Study on Quality Standard for Compound Tongchang Granules

目的探讨复方通肠颗粒的质量标准。方法采用薄层色谱法对方中大黄、枳实、赤芍进行定性鉴别,高效液相色谱法测定辛弗林的含量。结果在薄层色谱鉴别中,检出了枳实、大黄、赤芍;在含量测定中,辛弗林进样量在0.412～1.648μg范围内与峰面积线性关系良好(r=0.9993),平均回收率为100.18%,RSD=1.26%(n=9)。结论所建立的定性、定量方法稳定可行、重复性好,可作为复方通肠颗粒的质量控制方法。

Objective To establish the quality stadard for Compound Tongchang Granules.Methods Ingredients of Fructus Aurantii Immaturus,Radix et Rhizoma Rhei,Cortex Magnoliae Officinalis,Radix Paeoniae Rubra,Natrii Sulfas were identified by TLC.Synephrine was determined by HPLC.Results Fructus Aurantii Immaturus,Radix et Rhizoma Rhei,Radix Paeoniae Rubra,Natrii Sulfas were detected by TLC.Synephrine showed a good linear relationship within the range of 0.412-1.648μg,r=0.999 3.The arerage recovery was 100.18%, RSD=1.26%（n=9）.Conclusion The methods established are simple,feasible and reprodueible and can be used as the quality coutrol for Compound Tongchang Granules.
