摘　　要：对大豆卵磷脂进行羟氯化改性,以此为表面活性剂、乙醇为助表面活性剂,对胆固醇进行微乳化实验。采用三相图形式和电导率对微乳化体系进行跟踪检测。改性大豆卵磷脂与未改性大豆卵磷脂比较,在水中的分散性、微乳化性能明显提高,因此羟氯化改性卵磷脂可作为制备药物载体。Soybean lecithin was modified by hydroxychloride in NaClO. Then it was used as surfactant and alcohols were investigated as cosurfactant . Investigation of the phase and conductance were used for the microemulsion. Modified soybean lecithin was more effective than lecithin to improve the disperse and micromulsion,microemulsion of cholesterin and water was got,and it was better to be used in drug delivery system.
