Study on the optimum preparation condition of the new type podophyllotoxin liposome with orthogonal design

To select the optimum condition of the new type podophyllotoxin liposome preparation.The optimization of the new type podophyllotoxin liposome preparation was performed based on the orthogonal experimental design.The entrapment efficiency of the new type podophyllotoxin liposome were taken as the index and the influence of factors such as the proportion of hydrogenated phospholipid and Cholesterol,the proportion of hydrogenated phospholipid and PAMAM dendrimer G3.5 lipid globule,the proportion of hydrogenated phospholipid and podophyllotoxin and the temperature of rotary evaporation.The best formulation of the new type podophyllotoxin liposome were the proportion of hydrogenated phospholipid and Cholesterol was 20:3.26.the proportion of hydrogenated phospholipid and PAMAM dendrimer G3.5 lipid globule was 20:0.5,the proportion of hydrogenated phospholipid and podophyllotoxin was 20:1.5 and the temperature of rotary evaporation was 45℃.The new type podophyllotoxin liposome designed according to orthogonal experiment was coincidenced with the requirements in aspect of the liposome.
