The amounts of total lipids extracted from some but not all the algae examined were increased significantly by adding HCl to the usual chloroform-methanol extraction mixture. The Yield of phospholipid fraction relative to the glycolipids and neutral lipids increased significantly with acid extraction. Acid extraction also increased the yield of phosphatidyl serine, fatty acids, chlorophyll (or its derivatives) and several unknown compounds.
