A new galactolipid containing an eicosapentaenoyl (EPA) residue, named heterosigma-glycolipid II (2), was isolated from a cultured raphidophycean dinoflagellate Heterosigma sp., together with another new galactolipid heterosigma-glycolipid I (1).Based on enzymatic hydrolysis using lipase and physicochemicals evidence, the structures of heterosigma-glycolipids I (1) and II (2) have been determined as (2'S)-2',3'-di-O-(6,9,12,15-octadecatetraenoyl)-glyceryl β-D-galactopyranoside and (2'S)-2'-O-(6,9,12,15-octadecatetraenoyl)-3'-O-(5,8,11,14,17-eicosapentaenoyl)-glyceryl β-D-galactopyranoside, respectively.
