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, cholest-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.
