• Heterosigma-glycolipids I (1), II (2), III (3), and IV (4), four new Diacylglyceroglycolipids possessing ω3-polyunsaturated fatty acid residues, were isolated from the cultured raphidophycean dinoflagellate Heterosigma akashiwo.Based on enzymatic partial hydrolysis using lipase and physicochemical evidence. the structures of heterosigma-glycolipids I (1), II (2), III (3), and IV (4) have been determined as (2'S)-2', 3'-di-O-(6,9,12,15-octa-decatetraenoyl)glyceryl β-D-galactopyranoside, (2'S)-2'-O-(6,9,12,15-octadecatetraenoyl)-3'-O-(5,8,11,14,17-eicosapentaenoyl)glyceryl β-D-galactopyranoside, (2'S)-2'-O-(6,9,12,15-octadecatetraenoyl)-3'-O-(3,6,9,12,15-octadecapentaenoyl)glyceryl β-D-galactopyranoside, and (2'S)-2'-O-(5,8,11,14,17-eicosapentaenoyl)-3'-O-(6,9,12,15-octadecatetraenoyl) glyceryl 6-O-(α-D-galactopyranosyl)-β-D-galactopyranoside, respectively.
