Abstract
New acetylenic sterols, gelliusterol A (1, 26,27-bisnorcholest-5-en-23-yn-3 beta ,7 alpha -diol), its corresponding 7-ketone, gelliusterol B (2, 26,27 -bisnorcholest-5-en-23-yn-3 beta -ol-7-one), and gelliusterols C (4, choles t-5-en-23-yn-3 beta ,7-one) and D (5, cholest-5-en-23-yn-3 beta ,25-diol-7- one), were isolated from an unidentified species of sponge, Gellius sp. The structures of the steroids were established from spectroscopic data.
