Abstract: The unindentified chemical constituents were isolated and analyzed by column chromatography on silica gel, TLC, sephadex LH-20, and spectral analysis, especially by NMR techniques in the starfishAsteriasamurensisLutken. Four compounds were obtained and their structures were elucidated: Phallusid1(compound 1), N-(Cholest-5-en-3β-yl)-3β-hydroxyandrost-5-ene-17β- carboxamide (compound 2), Cholest-5,20 (22)-diene-3β-ol (compound 3), and (2S)-1-O-hepta-triacontanoyl glycerol (compound 4). The compounds 1, 2, 3, and 4 were isolated from the genusAsteriasfor the first time.
