The structure of 1 was elucidated by detailed analyses of 2D NMR spectra. Luteophanol D (1) possesses two tetrahydropyran rings and twenty-three hydroxyl groups on C63-linear aliphatic chain with one exo-methylene and two methyl branches. %K dinoflagellate %K Amphidinium sp. %K luteophanol D %K polyhydroxyl metabolite %U http://www.mdpi.com/1660-3397/3/4/113
