目的优选斑蝥素半乳糖化脂质体（Lac-CTD-lips）的最佳处方配比和制备工艺,并建立其含量测定的方法。方法采用薄膜分散法制备Lac-CTD-lips,采用GC-MS法建立斑蝥素含量测定的方法,以斑蝥素的包封率为评价指标,通过单因素考察结合正交试验,优化Lac-CTD-lips的制备工艺,并对其进行表征、包封率、粒径、Zeta电位考察。结果 Lac-CTD-lips最佳处方为斑蝥素-氢化大豆磷脂-胆固醇（1∶20∶5）、10%半乳糖苷;最佳工艺为50℃成膜,30 m L pH 6.0的PBS溶液洗膜,40℃下水合1.5 h。所得Lac-CTD-lips外观呈淡蓝色乳光,粒子形态呈球型,表面较圆整,无粘连。平均粒径为（123.9±4.8）nm（n=3）,粒径分布呈单峰,Zet...

Objective To optimize the formulation ratio and preparation process of galactosylated cantharidin liposome (Lac-CTD- lips) and establish its methodology for content determination. Methods The method of determination of GC-MS cantharidin content was established by film dispersion method. The entrapment efficiency of cantharidin was evaluated as an index. The preparation process of Lac-CTD-lips was optimized by single factor and orthogonal experiments. Its surface characteristics, encapsulation efficiency, particle size, and Zeta potential were a...
