title: Anasterocerebroside A, a new glucosylceramide from the Patagonian starfish Anasterias minuta.
abstract: Eight glucosylceramides (1-8) were isolated from the water-insoluble lipid fraction of a methylene chloride/methanol/water extract of the Patagonian starfish Anasterias minuta. One of the constituents was identified as a new glucosylceramide, anasterocerebroside A (1), while the known glucosylceramide 7 was isolated and characterized for the first time as a pure compound. The structures of 1 and 7 were established by spectroscopic and chemical methods.
