Pages: 638-640
Year: Issue:  10
Journal: CHINESE JOURNAL OF ANTIBIOTICS

Keyword:  硫酸多黏菌素E脂质体包封率透析法;
Abstract: 目的采用正交设计法筛选硫酸多黏菌素E脂质体的最优处方,建立透析法作为测定脂质体包封率的方法.方法逆相蒸发制备脂质体,紫外分光光度法测定硫酸多黏菌素E含量,正交设计法优化硫酸多黏菌素E脂质体处方.结果采用正交设计法筛选出的脂质体粒径均匀、外观较好,包封率可达50%.结论采用正交设计法可以方便的筛选出硫酸多黏菌素E脂质体的最优处方.采用透析法测定硫酸多黏菌素E脂质体的包封率准确性高、重现性好、简便易行.
