摘要：
A new rearranged triterpenoid, raspacionin-A (3), has been isolated from the encrusting red sponge Raspaciona aculeata. The structure was unambiguously determined by X-ray diffraction studies on its deacetyl derivative (4). All H-1- and C-13-NMR resonances of 3 and 4 were assigned by an extensive use of 1D and 2D NMR techniques. The absolute stereochemistry was assigned by applying Mosher's method to 4.
