Isolated eyespot granules of Euglena gracilis Klebs var. bacillaris Pringsheim contained approximately 6% lipids (based on protein). Separation of the lipid extracts by thin layer chromatography revealed four major fractions: wax esters, triacylglycerols, free fatty acids, and phospholipids. Methanolysis of each fraction yielded between 27 and 29 different fatty acids ranging from 12:0 to 22:6. Acetates of the fatty alcohols of the wax fraction consisted of 11:0 to 18:0 carbon chains, with 14:0 being the major component; unsaturated alcohols were not detected.
