Abstract

An aerosol liposome of a marine extract and a method of producing the same are introduced. The marine extract is extracted from cell membranes of marine processing streams, including phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and lysophosphatidylcholine (LysoPC), further including at least phosphatidylserine (PS). The aerosol liposome is of a particle diameter of less than 2,000 nm. The surface of the aerosol liposome carries phosphatidylserine (PS) molecules. The aerosol liposome of a marine extract is simple and stable and can be absorbed through the mouth, nose, upper respiratory tract, and epidermis and engulfed by macrophages therein to quickly alleviate or regulate systematic inflammatory responses and prevent inflammation-related diseases.

Claims

1. A method of producing an aerosol liposome, for producing an marine extract aerosol liposome, comprising the step of atomizing the marine extract into the aerosol liposome with an aerosol atomizer, wherein the marine extract is extracted from cell membranes of marine processing streams, comprises phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and lysophosphatidylcholine (LysoPC), includes at least phosphatidylserine (PS), and is characterized in that the aerosol liposome is of a particle diameter of less than 10,000 nm, and a surface of the aerosol liposome carries phosphatidylserine (PS) molecules.

2. The method of claim 1, wherein marine extract-derived solids, a marine extract-containing solvent, and a marine extract suspension are added to an aqueous solution to get diluted and atomized with an aerosol atomizer to synthesize the aerosol liposomes.

3. The method of claim 2, wherein a member selected from the group consisting of the nucleic acid matter, cytokine, and valent ion is added to an aqueous solution.
