Isolation of diacylglyceryl-2-aminoethylphosphonate from bovine liver

Diacylglyceryl-2-aminoethylphosphonate was isolated from bovine liver by a combination of silicic acid column and silica gel thin-layer chromatographic techniques, and was identified from the results of elementary analysis, the infrared spectrum, chemical properties, and chromatographic behavior. This is the first isolation of a lipid-bound form of ciliatine in mammals.
