Ein Verfahren zur quantitativen Isolierung reiner Sphingomyeline aus Menschen‐ und Rattenhirn

Abstract
A chromatographic method for the isolation of sphingomyelines from human and rat brain is reported. After isolation of the total lipids we first separate lecithine and sphingomyeline, on a silicagel column. Afterwards lecithine is split by transesterification with sodium methoxide. The cleavage products are separated from sphingomyeline on a silicagel column. Sphingomyeline is then purified on an alumina column. It shows an N: P relation of 2:1, is free of carbohydrates and ester linkages and can be obtained in a yield of 87%.
