Preparation And Characterization Of Galanga Essential Oil Liposomes

Galanga essential oil (GEO) liposomes were prepared by ethanol injection method and were characterized by size, polydispersity index (PDI) and zeta potential. Furthermore, the quality evaluation was conducted using the morphology observation and preliminary stability test. It was shown that Galanga essential oil-loaded liposomes embraced a mean particle size of 61.87 +/- 0.21 nm, the zeta potential was -16 +/- 0.99 mV, respectively. According to electron microscope observation, GEO liposomes signified a spherical structure. Preliminary stability studies pointed out that it exhibited good stability in a light-avoiding environment at 4 degrees C with stable size distribution.
