PROCESS FOR PRODUCING SPHINGOMYELIN AND PLASMALOGEN-FORM GLYCEROPHOSPHOLIPID

摘要

A process for producing sphingomyelin and plasmalogen-form glycerophospholipid, characterized by comprising:(A) a step in which all lipids are extracted 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 aliphatic hydrocarbon solvent and a water-soluble ketone solvent to separate the lipids into an insoluble part consisting mainly of sphingomyelin and a soluble part; (C) a step in which the insoluble part consisting mainly of sphingomyelin obtained in the step (B) is extracted with a solvent mixture of water 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 plasmalogen-form glycerophospholipid. Thus, high-purity sphingomyelin, especially human sphingomyelin, and a plasmalogen-form glycerophospholipid can be produced in a satisfactory yield from the skin of a chicken by a simple operation.
