title: [Chemical constituents of a new species of Spongia sponge].
abstract: Chemical constituents of a new species of Spongia sponge collected from Sanya bay in Hainan province, were analyzed. Nine secondary metabolites 1-9 were isolated. On the basis of their spectroscopic data and chemical degradation, their chemical structures were determined as palmitoyl-heptacosane-1, 3, 5-triol (1), stigmast-4-en-3beta, 6beta-diol (2),2,3-dihydroxypropanyl hentetracosanate (3), sitosterol (4), thymine (5), gorgosterol (6), batyl alcohol (7), uracil (8) and thymidine (9). Palmitoyl-heptacosane-1, 3, 5-triol (1) is a new compound.
