Abstract:

Epigallocatechin gallate (EGCG) liposomes (EL) were prepared by membrane-ultrasonic dispersion using soybean lecithin and cholesterol as encapsulation materials. The effects of the amount of cholesterol, hydration temperature, ultrasonic time, EGCG addition amount on the particle size, PDI, entrapment efficiency and yield of EL were studied. Also, the transdermal performance and the storage stability of EL were measured. The results show that, when the mass ratio of lecithin to cholesterol is 1∶0.25, the ultrasonic time is 6 min, the hydration temperature is 50 ℃, and the mass ratio of EGCG to lecithin is 0.075∶1, the high encapsulation efficiency and yield are achieved as 84.75%±2.12% and 93.78%±2.16%, and the particle size is (132.74±1.03) nm, the PDI is 0.245±0.009. According to the storage stability and transdermal experiments, liposomes can improve the transdermal transport and stability of EGCG significantly compared with the EGCG aqueous solution.

Key words: epigallocatechin gallate liposomes, preparation, skin penetration, stability
