Strongylophora durissima

Capillary GC analysis of the sterols of the Caribbean Xestospongia species, containing predominantly xestosterol (27), indicated a new sterol, xestospongesterol (31) which was separated by reversed-phase HPLC [22]. The structure was determined by mass spectrometry and NMR as a hitherto unprecedented quadruply biomethylated sterol. From the Indopacific sponge Strongylophora durissima, which has been reported to contain over 90% of strongylosterol, a new sterol named...
