摘要:

采用超临界二氧化碳抗溶剂法制备聚乳酸-羟基乙酸共聚物(curcumin-encapsulated poly (lactic-co-glycolicacid),PLGA)包埋姜黄素的纳米颗粒。以姜黄素包埋率为优化指标,利用响应面试验设计方法,系统考察芯材比、PLGA溶液流速、超声功率3 个因素对PLGA包埋姜黄素的影响。结果表明:当PLGA与姜黄素质量比3∶1、PLGA溶液流速1.8 mL/min、超声功率180 W时,包埋率达到93.89%。姜黄素-PLGA颗粒平均粒径为90 nm,粒径分布窄。

Abstract:

Curcumin-encapsulated poly (lactic-co-glycolic acid)(PLGA) nanoparticles was prepared using supercritical
carbon dioxide antisolvent assisted with ultrasound and the preparation process was optimized by response surface
methodology. The effects of the mass ratio of curcumin to PLGA, the flow rate of solution, and ultrasonic power on
properties of curcumin-encapsulated PLGA nanoparticles were investigated. The optimal conditions were determined
as follows: the mass ratio, 3:1; the flow rate, 1.8 mL/min; and the ultrasonic power, 180 W. Under these conditions, the
embedding rate reached 93.89%, and the average particle size was about 90 nm with a narrow distribution.
