Two new uncommon polyunsaturated amino ketones, (6 Z ,9 Z ,12 Z ,15 Z )‐1‐[(2‐phenylethyl)amino]octadeca‐6,9,12,15‐tetraen‐3‐one ( 1 ) and (6 Z ,9 Z ,12 Z ,15 Z )‐1‐(diethylamino)octadeca‐6,9,12,15‐tetraen‐3‐one ( 2 ), were isolated from the Gangxi sponge Haliclona sp. The structures of new compounds 1 and 2 were determined by detailed analysis of their 1D‐ and 2D‐NMR spectra, and high‐resolution mass spectrometry.
