In order to optimize the process of Hovenia dulcis-Phyllanthus emblica extract co-encapsulated microcapsules and improve the processing and storage characteristics of Hovenia dulcis-Phyllanthus emblica extract， the microcapsule was maded by spray drying method. Taking flavonoid embedding rate， polyphenol embedding rate， flavonoid drug loading and polyphenol drug loading as investigation indexes， the analytic hierarchy process-criteria importance though intercrieria correlation (AHP-CRITIC) method was used to determine the weight coefficients of each index and establish a comprehensive scoring system for microcapsules. Response surface methodology was used to optimize the preparation conditions of microcapsules. The physicochemical properties and structural characterization of microcapsules were analyzed. The results showed that the optimum conditions for the preparation of extract microcapsules by spray drying method of core-wall ratio， inlet-air temperature and wall material mass ratio (maltodextrin and gum arabic) were 2∶3.5， 162.5 ℃ and 1∶1.39， respectively. Under this condition， the microcapsules had uniform particle size and complete structure， with a particle size of about 3.833 μm and a comprehensive score of 67.498. The study on microcapsule performance showed that the wall material composition of maltodextrin and gum arabic could be a good co-encapsulate on the Hovenia dulcis-Phyllanthus emblica extractive， and improve the heat stability， moisture resistance and storage stability of the extractive.
