Lipophylic metabolites from the marine sponge Ircinia muscarum and its cell cultures

The composition of the lipophylic extract from the sponge Ircinia muscarum and its cell cultures developed under light and dark conditions was investigated. Lipids and their fatty acids, as well as volatile compounds and sterols, were identified. The differences between the two cell cultures did not appear to be very significant, while there were significant differences between the sponge and the cell cultures. Most of the isolated compounds were found for the first time in dictyoceratide sponges.
