To obtain the optimized extraction technology of Paeonia suffruticosa by comparing several extraction method. Extract P. suffruticosa by ethanol circumfluence, distillation-decoction, CO2-SFE and traditional decoction, and analyse the results according to the total extraction rate, extraction rate of paeono, extraction of other ingredients and production feasibility. Total extraction rates of which are 12.66%, 13.51%, 7.28%, 7.56% respectively; extraction rates of paeonol are 2.45%, 2.26%, 0.31%, 1.15% in turn; Phenolic glycosides can be extracted by ethanol circumfluence, distillation-decoction, traditional decoction, but not by CO2-SFE. Distillation-decoction is the most proper extraction technology of P. suffuticosa at present.
