Abstract
A process for the separation and purification of individual phospholipids, especially phosphatidylcholine or lecithin and phosphatidylethanolaine, from mixtures containing members of the sub-class of phosphatides, incorporating methods of solvent extraction appropriate to the scale of the sample and utilizing an acetonitrile, acetonitrile-hydrocarbon, or acetonitrile-fluorocarbon solvent, which exhibit differential solubility properties towards the individual phospholipids.
