The chemical investigation of secondary metabolites of a species of marine sponge, Spongia officinalis collected from the Aegean Sea was carried out. Two metabolites, namely ergosterol and furospinulosin-II, were isolated from the ethanolic extract of the sponge and their structure elucidations were performed by spectroscopic techniques and comparing with literature. As a common sterol and the precursor of vitamin D2 in higher plants, fungi, algae and rare sponges, ergosterol and furospinulosin-II, a furanoterpene, are reported for the first time from the marine sponge Spongia officinalis L.
