Chemical composition of the sponge Chondrosia reniformis from the Canary Islands

Abstract

The fatty acid composition of the lipids from Chondrosia reniformis (Nardo, 1847) was investigated and 57 acids were identified. One of them is new for nature and its structure was elucidated by GUmass-spectrometry. This acid was identified as 8.10-dimethyl-l6:O. The sterol composition was relatively simple and only 13 sterols were\npresent. In the volatile fraction, 21 compounds were identified, mainly fatty acids, their esters and hydrocarbons, while in the n-butanol fraction we found mainly free fatty acids and free arnino acids, together with significant amounts of sterols which probably are included in some polar complexes.
