Study on Water Extraction Process of Compound Shenqi Wuwei Chewable Tablets

Objective： To establish the optimal extraction process of compound Shenqi Wuwei chewable tablets. Method： The orthogonal design table L9 （ 3^4 ） was applied to design the extraction process of compound Shenqi Wuwei chewable tablets and the content of astragaloside Ⅳ was determined by HPLC-ELSD. The content of astragaloside IV and the extraction yield of crude drugs were used as the indicators to optimize the extraction technology. Dikma Diamonsil-Cls （ 250 mm ×4. 6 mm, 5μm） column was used. The mobile phase consisted of acetonitrile-water （32：68 ） with a flow rate of 1.0 ml. min^-1 at room temperature. Result： The optimal extraction process was as follows：decocting extraction for 3 times with 10-fold volume of water and 1.5 hours each time. Conclusion： The extraction is entire, and the detection methods are simple, sensitive and reproducible.
