  • Patent number: 8217199
    Abstract: The invention relates to a stable water soluble composition containing lithophosphatidylethanol amine (LPE) or lecithin including the LPE 3% or more. The composition comprises one or both of lysophosphatidylethanol amine and lecithin 0.1 to 50 wt %, fatty acid or salt thereof 0.1 to 60 wt % and solvent 10 to 99.8 wt %. According to the invention, it is possible to provide the stable water soluble composition of lithophosphatidylethanolamine and lecithin which does not cause the precipitation at the room temperature below 20° C. and can maintain the clear formulation even during the long term keeping.

  • Patent number: 6773902
    Abstract: 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.

  • Patent number: 6610313
    Abstract: The present invention discloses improved lysophospholipids composition having water-solubility in order to solve a conventional problem accompanying only the use of LPE as an anti-aging lysophospholipid caused by water-insoluble property thereof, comprising subsidiary lysophospholipid components, that is, LPI and LPC other than LPE to inhibit aging processional lysophospholipids, thereby forming an enhanced water-soluble lysophospholipids composition conveniently useable in plants and/or animals applications.
