Kaul and Lester (10) reported the preparation of six novel glycophosphoceramide fractions from the above crude concentrate from tobacco leaves. The crude concentrate was first resolved into two groups by column chromatography on diethyl aminoethyl-cellulose. The first group contained no acetyl residues, whereas the second group contained one N-acetyl per phosphorus. Three lipid fractions from each group were further resolved by chromatography on Porasil columns. The chemical composition and the percent of the total P in the crude concentrate of these lipid frac-...
