Abstract: This article was aimed to study the optimum extraction process of paeonol. The extraction yield of paeonol was taken as investigation index. And the best extraction process was screened by orthogonal experimental design. The results showed that the optimum condition of extraction process was to soak coarse powder of Paeonia suffruti-cosa into 15-fold water for 0.5 h, and then the distillation lasted for 2.5 h. The distillate was collected and cooled to room temperature. The crystallization lasted for 24 h at 4℃, and then filtered and dried for 48 h at room tempera-ture. It was concluded that the selected technology was stable, reasonable and feasible. The extraction yield of paeonol is over 80%.
