A new unsaturated glycoglycerolipid from a cultured marine dinoflagellate Amphidinium carterae

Abstract

From the cultured marine dinoflagellate Amphidinium carterae, a new unsaturated glycoglycerolipid (2S)-1,2-O-6,9,12,15-dioctadecatetraenoyl-3-O- [α-D-galactopyranosyl-(1″″→6‴)-O-β-D- galactopyranosyl]-glycerol (1), has been isolated together with two known saturated ones, (2S)-1,2-distearoyl-3-0-(6-sulpho-α-D-quinovopyranosyl)- glycerol (2) and (2S)-1-stearoyl-3-O-(6-sulpho-α-D-quinovopyranosyl)- glycerol (3). Their structures were elucidated on the basis of chemical and spectral data. © 2005 Pharmaceutical Society of Japan.
