SIMON POTATO EXTRACT, GLYCOSPHINGOLIPID DERIVED FROM SIMON POTATO, AND PROCESS FOR PRODUCTION OF THE EXTRACT OR GLYCOSPHINGOLIPID

摘要

[PROBLEMS] To provide a process for producing a glycolipid-containing Simon potato extract or a glycosphingolipid from a Simon potato for the purpose of providing an alternative to a livestock brain ganglioside which is free from the risk of BSE or the like, is safe to a human body and can be ingested on a daily basis, and to provide a nerve cell activator comprising a glycolipid or glycosphingolipid derived from a Simon potato and a health food prepared by using the glycolipid or glycosphingolipid. [MEANS FOR SOLVING PROBLEMS] A Simon potato extract can be produced by immersing a Simon potato in a polar solvent to extract a glycolipid or glycosphingolipid into the polar solvent and then concentrating the resulting immersion fluid. The nerve cell activation effect of the glycolipid or glycosphingolipid is confirmed using an established neuroblast.
