摘要

目的:制备姜黄素（Curcumin

Cur）脂质体并考察其包封率及稳定性。方法:采用逆相蒸发法制备Cur脂质体

葡聚糖凝胶柱层析法分离含药脂质体与游离药物并测定包封率;正交设计优选制备处方;离心加速实验与渗漏率的测定考察脂质体的稳定性。结果:所得优化处方为磷脂与药物的重量比60:1

磷脂与胆固醇的重量比4:1

pH6.5的磷酸盐缓冲液水合递质

超声时间为5min。以优化处方制得的脂质体平均包封率达95.06%。结论:选用逆相蒸发法优化Cur脂质体处方合理

工艺简便可行

包封率高

稳定性好。

Abstract

Objective:To prepare curcumin liposome and investigate its stability.Methods:Curcumin liposome was prepared by the reversed-phase evaporation method and purified by exclusion chromatography with Sephadex-50.The optimum formation was selected by means of orthogonal design of experiment;Centrifugal acceleration experiment and determination of leakling ration were served to proved the liposome stability.Results:The optimum formula was as follows:the ratio of lecithin to drug was 60∶1;lecithin:cholesterol was 4∶1;pH of PBS was 6.5

ultrasonic time was 5min.The average entrapment efficiency for curcumin was 95.06%.Conclusion:The selected formulation and preparation technique of curcumin liposome is reasonable in prescription

practicable in techniques

high in encapsulation efficiency and good in stability.
