Objective:To prepare gentiana total glucosides liposomes,and to study its release in vitro and percutaneous penetration.Methods:Gentiana total glucosides liposomes were prepared by reverse evaporation method.The orthogonal design experiment was used to optimize the preparation process of liposomes with the encapsulation efficiency as the index.The dynamic membrane dialysis and Franz diffusion cells method were respectively used to perform release in vitro and percutaneous permeation.Results:The optimum prep...
