Abstract:
A method for preparing a liposome, comprising the step of: (1) dissolving a substance to be encapsulated and phospholipid in an organic solvent to obtain an organic phase, and then mixing the organic phase with water to obtain a liposome feed liquid; (2) extruding the liposome feed liquid obtained in step (1) by means of a polycarbonate membrane; and (3) lyophilizing same.

Claim (Index 5):
The method according to  claim 1 , wherein the phospholipid is one or more selected from the group consisting of yolk phosphatidylcholine, hydrogenated yolk phosphatidylcholine, soybean phosphatidylcholine, hydrogenated soybean phosphatidylcholine, dipalmitoyl phosphatidylcholine, didecanoyl phosphatidylcholine, dipalmitoyl phosphatidylcholine, phosphatidylserine, phosphatidylinositol, phosphatidyl ethanolamine, phosphatidyl ethanolamine Pegol, phosphatidyl glycerol, phosphatidylcholine, dicetyl phosphate, dimyristoyl phosphatidylcholine, distearoyl phosphatidylcholine, dilauroyl phosphatidylcholine, dioleoyl phosphatidylcholine, dierucoyl phosphatidylcholine, 1-myristoyl-2-palmitoyl phosphatidylcholine, 1-palmitoyl-2-stearoyl phosphatidylcholine, 1-palmitoyl-2-myristoyl phosphatidylcholine, 1-stearoyl-2-myristoyl phosphatidylcholine 1-stearoyl-2-palmitoyl phosphatidylcholine, 1-myristoyl-2-oleoyl phosphatidylcholine, 1-palmitoyl-2-oleoyl phosphatidylcholine, 1-stearoyl-2-oleoyl phosphatidylcholine, dimyristoyl phosphatidyl ethanolamine, dipalmitoyl phosphatidyl ethanolamine, distearoyl phosphatidyl ethanolamine, dioleoyl phosphatidyl ethanolamine, dierucoyl phosphatidyl ethanolamine, and 1-palmitoyl-2-oleoyl phosphatidyl ethanolamine; preferably, the phospholipid is one or more selected from the group consisting of yolk phosphatidylcholine, hydrogenated yolk phosphatidylcholine, soybean phosphatidylcholine and hydrogenated soybean phosphatidylcholine; more preferably, the phospholipid is a combination of yolk phosphatidylcholine and hydrogenated soybean phosphatidylcholine; and still more preferably, the phospholipid is a combination of yolk phosphatidylcholine and hydrogenated soybean phosphatidylcholine, wherein a weight ratio of yolk phosphatidylcholine to hydrogenated soybean phosphatidylcholine is 3:1.
