Japanese Patent JP4045100

B2

Disclosed herein is a method for purifying the lysophosphatidylethanolamine with high purity by treating the phospholipid mixture with enzymes, followed by solvent fractionaltion without the column purification. The method of the present invention comprises hydrolyzing phospholipid mixture containing 10-99 weight % of phosphatidylethanolamine with phospholipase A2 to produce lysophospholipid; and treating the lysophospholipid with the solvent mixture comprising water and one or more organic solvents selected from the group consisting of low alcohol, hydrocarbon and alkylester to eliminate impurities except lysophosphatidylethanolamine.
