procedure for isolation of phosphatidylcholine from aeggepulver lysophosphatidylcholinfrit

摘要

A process for isolating phosphatidylcholine free of lysophospholipid from egg powder wherein the egg powder is treated with a solvent mixture of a low boiling petroleum ether fraction (40 DEG to 80 DEG C.), a lower C1-C4-alkanol and water, the undissolved material is separated from the solution phase, the solution phase is given onto a column filled with silica gel at a temperature in the range from 20 DEG to 50 DEG C., the elution is carried out at that temperature with the same solvent mixture, the main run is collected and the dissolved phosphatidylcholine is isolated therefrom as usual.
