Abstract

An investigation of the MeOH soluble fractions of marine sponge Psammocinia sp. (Order: Dictyoceratida) led to the isolation of a new epidioxy sterol (1) and four known sterols (2-5). Their planar structures were defined by analyses of the spectroscopic data. The 27-nor-24-methylcholestan type side chain with an epidioxy nucleus (1) was unprecedented. Compounds 1-5 were isolated from a sponge Psammocinia sp. for the first time.
