title: Chemical composition of the sponge Hymeniacidon sanguinea from the Canary Islands.
abstract: The fatty acid composition of the lipids from the sponge Hymeniacidon sanguinea was investigated and 73 acids were identified. Three of them were new and their structures, elucidated by gas chromatography/mass spectrometry, were identified as 13-methyl-icosanoic, 15-methyl-docosanoic and 3,13-dimethyl-tetradecanoic. Only 12 sterols were present, with cholestanol predominating in the volatile fraction; 22 compounds were identified, mainly hydrocarbons and fatty acids. In the n-butanol fraction, we found mainly nitrogen-containing compounds. The compositions of sterols and lipids in the sponge collected from two locations with different ecological conditions (Canary Islands and Black Sea) were compared.
