Document Type and Number:
Japanese Patent JPH05163153
Kind Code:
A
Abstract:
PURPOSE: To provide a new sphingolipid composition resistant to the generation of ill odor and discoloration during long-term storage and to provide a process for producing the sphingolipid composition.
CONSTITUTION: The objective sphingolipid contains (a) galactosyl cerebroside, (b) galactosylcerebroside sulfate and (c) sphingomyelin at an (a+b)/c ratio of 65/35 to 85/15. The content of sphingolipid in the above three components is ≥90% and that of glycerophospholipid is ≤2%. The composition can be produced by hydrolyzing a lipid mixture obtained from a cerebral nerve of mammal with an alkali, distilling out the solvent used in the hydrolysis, washing with a mixture of acetone and water and collecting the insoluble component.
