    Notes: Three ganglioside molecular species, HPG-8, HPG-3, and HPG-1, have been obtained from the polar fraction of the chloroform/methanol extract of the sea cucumber Holothuriapervicax. The structures of these gangliosides have been determined on the basis of chemical and spectroscopic evidence. They represent new ganglioside molecular species. HPG-8 is a sulfated monosialo-ganglioside, while HPG-3 and HPG-1 are disialo-gangliosides possessing 2→4-linked tandem-type disialosyl moieties. These three gangliosides qualitative neuritogenic activity toward the rat pheochromocytoma cell line, PC-12 cells.

    Notes: Five cerebrosides, CE-1-1, CE-1-2, CE-1-3, CE-3-1, and CE-3-2, and a ganglioside molecular species CG-1 have been obtained from the less polar and polar fractions, respectively, of the chloroform/methanol extract of the sea cucumber Cucumaria echinata. The structures of these glycosphingolipids have been determined on the basis of chemical and spectroscopic evidence. The cerebrosides show lethality toward brine shrimps. On the other hand, the ganglioside CG-1 exhibits neuritogenic activity toward the rat pheochromocytoma cell line, PC-12 cells.
