OBJECTIVE To study the chemical constituents of Dendronephthya gigantea. METHODS The compounds were isolated and purified by silica gel, Sephadex LH-20, and semi-preparative reverse-phase HPLC. Their structures were identified by their physical and spectral data. RESULTS Ten compounds were isolated from Dendronephthya gigantea and their structures were identified as (4E, SE)-2(hexadecanoylamino)-4,8-octadecadiene- 1,3 -diol(1),(4E)-2(hexadecanoylamino)-4-octad- ecane- 1,3-diol (2), N-phenethylacetamide (3),Cyclo-(Leu-Pro) (4), Cyclo-(Ala-Pro) (5), Cyclo-(Val-Pro) (6), 2,4-dichlorobenzoic acid(7), thymidine (8), 2'-deoxyuride (9), cholesterol (10). CONCLUSION Compound 1-9 were isolated from Dendronephthya gigantea for the first time.
