Abstract: The liposome of volatile oil from Houttuynia cordata Thunb. was prepared by modified rapid expansion of supercritical solutions (RESS), and physicochemical properties of liposome were characterized. The effects of pressure, temperature of supercritical CO2 and cosolvent (CH3CH2OH) amount on the liposome formation process were examined. Entrapment rate, drug loading, and average size of liposome were obtained as 83.2%, 5.2% and 332.5 nm respectively under the conditions of 30 MPa, 338 K and CH3CH2OH 15%. The results showed that the physicochemical properties including entrapment rate, dissolution rate and stability conformed to the standards of Chinese pharmacopoeia, and drug loading met the needs of injection dosage.
