[Preparation and evaluation of four kinds of mixed essential oil liposomes in Jieyu Anshen Formula].

In order to increase the stability and solubility of essential oil in Jieyu Anshen Formula, this study was to prepare the essential oil into liposomes. In this experiment, the method for the determination of encapsulation efficiency of liposomes was established by ultraviolet spectrophotometer and dextran gel column. The encapsulation efficiency and particle size of liposomes were used as evaluation indexes for single factor investigation and...
