Abstract
Egg yolk phospholipids, on a 10 g scale, were resolved by high-performance liquid chromatography on an 8-m silica column with elution by a stepwise chloroformmethanol gradient into homogenous phosphatidylcholine, phosphatidylinositol, phosphatidylethanolamine, and lysophosphatidylethanolamine fractions. Within these fractions, partial resolution on the basis of fatty acyl side chain composition was achieved.
