Three compounds have been isolated from the algae Sargassum polycystcum collected fromthe North China Sea. Their structures were established as stigmast-5,23,25-triene (1), 3-pentacosox-1,2- propanediol (2), 24ξ-methylcholestane-3β, 5α, 6β, 25-tetrol-25- acetate (3) by MS, IR, ~1D NMR, ~2D NMR and elemental analysis. Compound 1 is a previously unknown compound.
