Quantitative gas-liquid chromatographic analysis of ethanolamine, monomethyl ethanolamine, and dimethyl ethanolamine from lipids.

A method for the separation and quantitative estimation of ethanolamine, dimethyl ethanolamine, and monomethyl ethanolamine derived from lipids is described. After acid hydrolysis of the lipids, the bases are extracted from the neutralized hydrolysate with t-butonol and separated by gas-liquid chromatography.
