【Abstract】 OBJECTIVE:To optimize the prescription and preparation of matrine liposomes.METHODS:The liposomes were prepared by the reverse-phase evaporation technique;the envelope efficiency and the diameter of matrine liposomes were taken as criteria,the prescription and preparation of the liposomes were optimized by orthogonal design.RESULTS:The best prescription consisted of egg phosphatidylcholin(80mg),the oil phase cholesterol(15mg),the water phase phosphate buffer soˉlution(pH=7.0)and matrine(30mg);the best preparation technics was as follows:chloroform(30ml),ultrasonic time was10min rotary evaporating temperature at48℃.The liposomes had homogeneous shape with the particle size at250nm～750nm and the envelope efficiency of matrine liposomes at47.25%.CONCLUSION:The optimized formulation of martine liposomes is reasonable in prescription,practicable in technics,high in envelope efficiency and perfect in stability.更多还原
