Objective: To optimize the extraction process of Ru'an gel cream. Method: The optimum extraction process was selected by orthogonal test.The content of icariin
total flavones from Epimedh Folium and tetrahydropalmatine as indexes. Result: Extraction process of Epimedh Folium was as follows:reflux extract 3 times with 15 times of water
1 h per time. Extraction process of Corydalis Rhizoma was as follows:reflux extract 3 times with 15 times of 50% ethanol
1.5 h per time. The transfer rate of icariin
total flavones from Epimedh Folium and tetrahydropalmatine were 62.64%、83.83%and 93.27%. Conclusion: The optimum extraction technology is resource-saving
