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.

Abstract: Disclosed are a method, composition and kit for promoting plant growth and improving plant preservation. According to the invention, it is possible to improve qualities of agricultural products and preservation of crops after harvested as well as to increase production of crops by promoting plant growth without using toxic chemicals.

Abstract: Lysophosphatidylethanolamine has skin whitening ability and thus a composition containing lysophosphatidylethanolamine as an active ingredient can be used to relieve hyperpigmentation or discoloration. The composition containing lysophosphatidylethanolamine can also induce moisturizing effect on skin, is very safe, and very stable.

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.

Abstract: The present invention relates to a process for preparing lysophospholipid using enzyme, more specifically, a process for preparing lysophospholipid from glycerol-3-phosphate derivative using lipase based upon esterification or transesterification reaction.
