摘要：

The novel very long chain (5Z,9Z)-2-methoxy-5,9-hexacosadienoic acid (1) was identified in the phospholipids of the Caribbean sponge Tropsentia roquensis. The new acid (5Z)-2-methoxy-5-hexadecenoic acid (2) was also identified in the phospholipids of the sponge Mycale laxissima while the acid (6Z)-2-methoxy-6-hexadecenoic acid (3) was found to be present in the phospholipids of the Caribbean sponge Spheciospongia cuspidifera.. The double bond positions in the monounsatutared acids were determined by GC/MS on the corresponding dimethyldisulfide adducts and the double bond stereochemistry was elucidated by GC/FTIR. These fatty acids were found in phosphatidylethanolamine.
