Abstract: The orthogonal test was used to optimize the decoction process of Shenqi Qiangjing granules,and the best moulding process was determined by single factor test. The thin layer chromatography（TLC）was performed to identify Epimedium and Schisandra Chinensis, the quality standards of Shenqi Qiangjing granules was established. The results showed that the optimum extraction process was 10 times amount of water and fried and extracted three times for 1.5 h each; The optimum moulding process was the ratio of thick paste and dextrin of 1∶1, 65% ethanol as the wetting agent, and 0.3% stevia as the correction agent, the obtained granulas had good solubility, good forming properties and appropriate taste; The spots of qualitative identification of Epimedium and Schisandra Chinensis were clear, the identification method was simple and feasible, and could be used as an internal control standard for the quality of Shenqi Qiangjing granules.
