大七厘散质量标准的研究

Study of quality standard for Daqili powder

目的建立大七散的质量标准。方法采用高效液相色谱法对大七厘散中的主要成分人参皂苷Rg1进行定量分析,λ=203nm;同时对制剂中其他主要药材大黄、冰片、当归尾进行薄层鉴别。结果能准确对大黄、冰片、当归尾进行定性鉴别;人参皂苷Rg1在0.5710～4.2840μg范围呈良好线性关系。结论本方法快速、简便、准确、重现性好。

OBJECTIVE To study the quality standard for Daqili powder. METHODS HPLC was used to measure the content of ginsenoside Rg1. The detective wavelength was 203nm. TLC was used to qualitatively differentiate among Radix Et Rhizoma Rhei, Synthetic borneol and Radix Angelicae Sinensis Tail in Daqili powder. RESULTS Radix Et Rhizoma Rhei, Synthetic borneol and Radix Angelicae Sinensis Tail could be differentiated qualitatively by TLC. The linear range of ginsenoside Rgl was 0. 5710- 4.2840ug.CONCLUSION The methods is rapid, simple and accurate. It can be used for the quantitative determination of Daqili powder.
