| Abstract: | OBJECTIVE： To optimize the extraction technology of Gegen qinlian decoction. METHODS： The extraction technology of Gegen qinlian decoction was optimized by orthogonal experiment taking the contents of puerarin, baicalin, and the yield of solid substance as indexes with the amount of solvent, the extraction time and extraction times as factors. RE- SULTS： The optimal extraction technology was as follows： 50% alcohol at an amount of 8-fold that of solid medicinal substance was added to the medicinal substance to be reflux extracted twice （1.5 hours/time）.CONCLUSION： The extraction technology was reasonable, stable and feasible, and it serves as theoretic basis for further development and utilization of Gegen qinlian decoction. |
