Abstract: OBJECTIVE To establish the processing Shangluo Pinellia origin drying process, for making medicine production standard operating procedure (SOP) to provide data support. METHODS The freshly mined Pinellia was randomly divided into four groups, using the methods of drying in the shade,the way of airing, drying in 60 ℃ and microwave.Taking pinellia doing rate, L-Left ephedrine,the leaching of water-soluble content as the observation target.And then the content of effective components were determined.RESULTS After being mined,Pinellia was cleaned,peeled of the four methods of drying,microwave in fire 3 min,Pinellia doing rate and the L- left ephedrine content were highest. CONCLUSION In producing Pinellia as a Chinese herbal medicine,we'd better use the method of microwave,which reduces labor intensity,saves drying time, also enhances the effective component content.
