Abstract By silicic acid column separation small quantities of glycolipid‐rich fractions have been isolated from commercial Swedish rapeseed “lecithin.” Major components in these fractions are monogalactosyl diglyceride and digalactosyl diglyceride which have been identified by R f on thin layer chromatography specific color reactions and IR spectrometry. The fatty acid patterns of the galactolipids are different from those of the major phospholipids of the same product, with less of palmitic and oleic and considerably more of linolenic acid.
