## Abstract Two new uncommon polyunsaturated amino ketones, (6__Z__,9__Z__,12__Z__,15__Z__)β1β[(2βphenylethyl)amino]octadecaβ6,9,12,15βtetraenβ3βone (**1**) and (6__Z__,9__Z__,12__Z__,15__Z__)β1β(diethylamino)octadecaβ6,9,12,15βtetraenβ3βone (**2**), were isolated from the Gangxi sponge __Haliclona
A new pentacyclic sulfated hydroquinone, phuklona sulfate, has been isolated from the marine sponge Haliclona sp. collected near Phuket Island, Thailand. The structure was elucidated by a variety of spectroscopic methods including 1D and 2D NMR experiments. Phuklona sulfate contains a novel triterpe
