The present invention provides marine lysophosphatidylcholine compositions for use in pharmaceuticals, nutraceuticals and functional foods, as well as methods for making marine lysophosphatidylcholine compositions.

The method of producing a lipid composition comprises an extraction treatment step to extract a lipid comprised in a hydrated raw material by using an extraction solvent comprising a polar solvent and a nonpolar solvent, and a separation treatment step to separate an extract solution obtained in the extraction treatment step into a polar solvent phase comprising a first lipid fraction and a nonpolar solvent phase comprising a second lipid fraction.

To provide an ether-type glycerophospholipid-containing composition that has excellent heat stability and also has oxidation stability and storage stability. An ether-type glycerophospholipid-containing composition that comprises not more than 20 mass % of an ether-type glycerophospholipid and not less than 80 mass % of a cyclodextrin. Owing to this constitution, the ether-type glycerophospholipid is clathrated in the cyclodextrin. Thus, the ether-type glycerophospholipid-containing composition has highly excellent heat stability as well as temporal stability such as oxidation stability and storage stability even in a powdery form.
