Glycolipids isolated from ginkgo nuts(Ginkgo biloba) and their fatty acid compositions

  • Published:
Journal of the American Oil Chemists’ Society

Abstract

The total amount of glycolipids isolated fromGinkgo biloba nut was 3.12% of crude lipids, and the largest fraction of the glycolipids was digalactosyldiglyceride 64.1%, followed by mono-galactosyldiglyceride 31.2% and cerebroside 4.7%. Chief fatty acids present in the former two were oleic and linoleic acids, while the main compo-nent amounting to 85% of total fatty acids in the last fraction was α-hydroxypalmitic acid. The sugar component in cerebroside was glucose, and its long chain base was found to be similar in structure with octadecasphingadiene that had been isolated from oyster glycolipids. The major compound in the cerebroside fraction, therefore, is considered to be N-α-hydroxypalmitoyl-glucosyloctadecasphingadiene.
