Objective To optimize the preparation process of puerarin polymeric micelles by orthogonal design. Methods Puerarin polymeric micelles was produced by using the method of film dispersion based on the cartier materials of mPEG-PCL. Taking the encapsulation efficiency of as the evaluation indexes, the preparation of puerarin polymeric micelles was optimized by a L9 （3^4） orthogonal design. Results The optimal formula of film dispersion method was： mPEG-PCL/puerarin （100：1） , water volume （25 mL） and hydration temperature （50 ℃） . The mean entrapment efficiency of three batches of samples was （35.5±2.12） %. Conclusion The technology of film dispersion method is feasible, good morphology and narrow particle size distribution.
