摘要
目的:考察硫酸铵梯度法制备马钱子碱脂质体的影响因素。方法:采用Sephadex G-50凝胶柱分离测定包封率,考察各工艺及处方因素对包封率的影响。结果:马钱子碱脂质体的包封率与硫酸铵浓度、乙醇体积、磷脂浓度等因素存在显著的正相关性。结论:硫酸铵梯度法可以用于马钱子碱脂质体制备并得到满意的包封率。硫酸铵浓度、乙醇体积和磷脂浓度是影响包封率的重要因素。
Objective: To study the influencing factors in preparation of brucine liposomes by ammonium sulfate transmembrane gradients. Methods: The brucine liposomes were separated by Sephadex G-50, and the influence of various factors on the entrapment effieieneies were investigated. Results: The entrapment efficiency was enhanced by increased ammonium sulfate concentration, ethanol volume and PC concentration. Conclusion: Burcine liposomes prepared by ammonium sulfate transmembranee gradients can get a high entrapment efficiency, the main influencing factors were ammonium sulfate concentration, ethanol volume and PC concentration.
