Quantitation of individual phospholipids separated by HPLC from tissue extracts by colorimetric analysis of phosphate was investigated. Elution of inorganic phosphate and breakthrough of lecithin were determined using radioisotopes. A substance which interfered with sample phosphate determinations was found in the column eluant, and a method to minimize its effect was developed. This method allows accurate quantitation of individual phospholipids present at a minimum of 20 nmol phosphate.
