A modified ethanol injection method for liposomes containing soybean phosphatidylcholine (SPC), cholesterol (Ch), beta-sitosterol beta-D-glucoside (Sit-G) and oleic acid (OA) was developed, that can produce homogeneous unilamellar liposomes without the use of sonication and dialysis. In this method, water is poured into a concentrated lipid-ethanol solution and then ethanol is removed in an evaporator. Dilution with water causes spontaneous formation of small and homogenous unilamellar vesicles from micellar aggregate. The size of liposomes can be controlled by the ratio of ethanol to water. OA and Sit-G were distributed at the surface of liposomes and were recognized by Concanavalin A, respectively. This easy and quick method for preparation of liposomes may be applicable in many areas.
