    Abstract：ObjectiveTo optimize the extract method of Rhizoma coptidis and the compound.MethodsCompare alcohol extraction with water extraction, single extraction with compound extraction. The orthogonal design was used to select the optimum extraction process.ResultsThe optimum extraction condition was as follows: adding ten folds of water and decocting 1.5h respectively and then adding eight folds of water and decocting 1h finally.ConclusionIt offered basis on research for preparation technology of Rhizoma coptidis.
