A two-dimensional thin-layer chromatographic procedure for the estimation of plasmalogens.
1. The use of two-dimensional thin-layer chromatography is described that allows the rapid and simultaneous determination of phospholipid classes and their constituent plasmalogens. 2. The method is based on the specific hydrolysis of plasmalogens to (2-acyl) lysophospholipid in the presence of a mercuric chloride spray reagent. 3. The proportion of mercuric chloride-labile phospholipid present in each phospholipid class, calculated on the basis of phosphorus recoveries from the charred chromatogram, was compared with the proportion of long-chain aldehyde and of total lipid phosphorus found in small-scale preparations of each class of phospholipid. 4. The method permits the determination of individual plasmalogens on preparations containing as little as 0.2mug.atom of total lipid phosphorus.
