摘要: 采用叶酸-壳聚糖复合物修饰纳米脂质体,用于包埋姜黄素,得到叶酸-壳聚糖修饰的姜黄素纳米脂质体。经叶酸-壳聚糖复合物修饰后,脂质体的粒径和电位分别由(67.4±2.3)nm和(-13.81±2.75)mV变为(103.6±4.1)nm和(16.35±3.54)mV;与姜黄素纳米脂质体相比,复合物修饰的姜黄素纳米脂质体在25?℃具有更好的贮存稳定性,两者均具有良好的缓释性能,且复合物修饰后的脂质体在弱酸性环境中释放速率较弱碱性更快。此外,修饰前后的空白脂质体均未检测出细胞毒性,且由于叶酸-壳聚糖复合物修饰能增加姜黄素脂质体的细胞摄取量,修饰后的姜黄素脂质体的细胞毒性大于未经复合物修饰的姜黄素脂质体。

Abstract: Folic acid-chitosan complex was applied to modify nanoliposomes containing curcumin. The average particle size and zeta potential of curcumin nanoliposomes were (67.4 ± 2.3) nm and (?13.81 ± 2.75) mV, and they were increased to (103.6 ± 4.1) nm and (16.35 ± 3.54) mV after being modified with folic acid-chitosan complex. The modified curcumin nanoliposomes showed better storage stability at 25 ℃ as compared to the native curcumin nanoliposomes and both of them possessed good sustained release property. Furthermore, curcumin was released faster from the modified nanoliposomes under weakly acidic conditions than under slightly alkaline conditions. Both the native and modified nanoliposomes without curcumin exhibited no cytotoxicity on Caco-2 cells, and the modified curcumin nanoliposomes possessed higher cytotoxicity than the native curcumin nanoliposomes, which was associated with higher cellular uptake percentage.

Key words: curcumin, folic acid, chitosan, liposomes
