Abstract
The alk-1-enyl and alkyl glyceryl ethers produced by hydrogenolysis of the parent lipids were separated from each other and from other hydrogenolysis products by silicic acid chromatography. The isolated ethers were acetylated and the diacetates fractionated by gas—liquid chromatography on the basis of the different aliphatic groups. The free and acetylated alk-1-enyl glyceryl ethers were characterized by thin-layer chromatography, chemical analysis and infrared spectroscopy in addition to gas—liquid chromatography. The feasibility of the method for the determination of the distribution of the aliphatic groups in the alk-1-enyl glyceryl ethers of rat brain and of the alk-1-enyl and alkyl glyceryl ethers in ox brain ethanolamine phosphoglycerides was demostrated.
