Objective: To investigate the secondary metabolites from Chinese marine Sponge
Cinachyrella australiensis. Methods: Column chromatography techniques including HPLC were used for the separation and purification of the compounds, and extensive spectral analyses including various 2D NMR spectra were employed for structure elucidation. Results: Nineteen compounds were obtained ,including 2 methyoxy 6,12,15 trien 8 yne octadecanoic
acid(1), 2 benzenedicarboxylic acid dibutyl ester(2), 1,2 benzenedicarboxylic acid bis(2 ethylhexyl)ester(3), ( ) (3S) 1,2,3,4 tetrahydro β carboline 3 carboxylic acid(4), L Tryptophan (5), p hydroxylbenzaldehyde (6), p hydroxyl benzylethanol(7), p hydroxyl benzyl propanol(8), cholesta 4 en 3 ol(9), 2 methyl 6
