A method is described for the preparation of ganglioside G lac 2 [(II 3 (NeuAc) 2 ‐LacCer, GD3] from cream of bovine milk using liquid‐phase extraction with methanol or ethanol followed by anion exchange chromatography. The method is rapid and inexpensive; 1 kg cream, centrifuged from 14–15 L of bovine milk, yields approximately 70 mg of pure ganglioside G lac 2. The sialic acid constituent of ganglioside G lac 2 isolated from bovine milk cream consists solely of the N ‐acetylneuraminic acid derivative. The major components of its ceramide consist of octadecasphing‐4‐enine and the 22∶0 (behenic acid) and 23∶0 fatty acids.
