Two poly substituted aromatic compounds: tetrahydroauroglaucin 1 and isodihydroauroglaucin 2 were identified from a marine fungus, Eurotium sp. isolated from leaves of the mangrove, Porteresia coarctata (Roxb). These compounds were reported earlier from terrestrial fungal source of the same genus. The structures of these compounds were finalized from their spectral data and comparison with literature values. Complete sup(1)H and sup(13)C NMR signal assignments are reported here for the first time based on extensive 2D NMR studies including COSY, HMQC, HMBC.
