A new glucocerebroside, linckiacerebroside A (1) and a known glucocerebroside S-2a-3 (2), have been isolated from the cerebroside molecular species obtained from the less polar fraction of the CHCl3/MeOH extract of the starfish Linckia laevigata , together with three pseudo homogeneous glucocerebroside, 3, 4, and 5. The structures of these cerebrosides were determined on the basis of chemical and spectroscopic evidence.
