Abstract
The pyridine-soluble lipids from tissue of corbicula afforded four main glycolipids. Purification was carried out by adsorption on activated silica gel and Florisil or by mild alkaline saponification.
Among these glycolipids, from the in-frared spectra and the analytical data or thin layer chromatograms, the one containing fatty acid, sphingosine, D-glucose, D-Xylose, L-fucose, glucosamine and galactosamine, or sometimes a related substance, is considered to be present. Especially, the presence of aminosugar phosphate, as a constituent, is an interesting finding.
The autheres are particularly indebted to Prof. T. Yamakawa of the University of Tokyo for his suggestions and encouragement during this investi-gation. They also express their gratitude to Dr. I. Matsubara of Toyo Rayon Co., Ltd. for the elemental analysis.
