To facilitate investigation of the metabolism of lysophosphatidylcholine and choline lysoplasmalogen in small quantities of tissue, a method for the quantification of these phospholipid species that is capable of accurate and reproducible analysis in samples which contain less than 1 nmol of total choline lysophospholipid was developed. The procedure employs chloroform and methanol extraction of phospholipids from isolated tissue with subsequent separation of the choline lysophospholipid fraction by high-performance liquid chromatography. The choline lysophospholipids are then acetylated with [3H]acetic anhydride and the [3H]acetyl-lysophosphatidylcholine product is isolated by thin-layer chromatography and quantified by liquid scintillation counting. The choline lysophospholipid content in the sample is determined from a standard curve constructed from samples containing a known amount of synthetic lysophosphatidylcholine with correction for recovery based on the inclusion of [14C]lysophosphatidylcholine as an internal standard.
