| 摘 要： | 目的研究非离子表面活性剂囊泡对钙黄绿素包封率的影响,为新型药物传输系统的研究提供一定的依据。方法以司盘60和胆固醇为主要原料,通过薄膜分散法制备了非离子表面活性剂囊泡,研究了该类囊泡对钙黄绿素的包封作用以及影响包封率的因素,并利用正交实验设计优化了其最佳包封条件。结果表面活性剂浓度、水化时间、水化温度、胆固醇用量、胆固醇与表面活性剂比例均对包封率有明显的影响。最佳包封条件为：胆固醇的摩尔质量0.2mol、水化时间45min、水化温度65℃、司盘60摩尔质量为0.3mol。结论非离子表面活性剂囊泡对钙黄绿素具有较强的包封能力,钙黄绿素可作为研究该类囊泡作为药物载体的模型药物。
