The fatty acids of the sponge Hymeniacidon sanguinea from the Black Sea

Abstract

The fatty acid composition of the sponge Hymeniacidon sanguinea from the Black Sea has been determined by methods involving silver ion HPLC and GC-MS. More than a hundred different fatty acids were identified, of which many were similar to those in sponges from tropical seas. By contrast, some of the fatty acids identified, including trans-6-hexadecenoic acid and 5,15-tetracosadienoic acid, may not have been found previously in sponges and other marine sources, and perhaps are new to science.
