PROCESS FOR PRODUCING SPHINGOMYELIN AND PLASMALOGEN-FORM GLYCEROPHOSPHOLIPID

摘要

A process for producing sphingomyelin and plasmalogen-form glycerophospho lipid, characterized by comprising:(A) a step in which all lipids are extrac ted from a chicken-skin powder and dried; (B) a step in which the dried all lipids obtained in the step (A) are extracted with a solvent mixture of an a liphatic hydrocarbon solvent and a water-soluble ketone solvent to separate the lipids into an insoluble part consisting mainly of sphingomyelin and a s oluble part; (C) a step in which the insoluble part consisting mainly of sph ingomyelin obtained in the step (B) is extracted with a solvent mixture of w ater and a water-soluble ketone solvent to remove the non-lipid ingredients from the soluble part; and (D) a step in which the soluble part obtained in the step (B) is dried and then extracted with a water-soluble ketone solvent to separate and recover an insoluble part consisting mainly of a plasmaloge n-form glycerophospholipid. Thus, high-purity sphingomyelin, especially huma n sphingomyelin, and a plasmalogen-form glycerophospholipid can be produced in a satisfactory yield from the skin of a chicken by a simple operation.
