1. A method for preparing triterpenoid liposome, which comprises the following steps of:
- (a) dispersing triterpenoid in a polyol while heating up to 60˜
70°
C. to prepare dispersion;
(b) adding a base into the dispersion of step (a) to prepare low viscosity dispersion;
(c) dissolving phospholipid in ethanol of a room temperature to prepare ethanol solution of phospholipid;
(d) adding the ethanol solution of step (c) into the dispersion of step (b);
(e) adding the mixture of step (d) into distilled water and then emulsifying to prepare emulsion; and
(f) adding an acid to the emulsion of step (e) to prepare submicron-liposome.
