To evaluate the cytotoxic activity of secondary metabolites from co-culture of Eurotium cristatum with Staphylococcus aureus, seven known compounds, including echinulin(1), cristatumin F(2), neoechinulin A(3), preechinulin (4), flvoglaucin (5), tetrahydroauroglaucine (6), and epiheveadride (7) are isolated from the solid culture of the co-culture of Eurotiumcristatum with Staphylococcus aureus. The structures are checked on the basis of spectroscopic analysis NMR experiments and by mass spectrometric measurements. These metabolites are evaluated in vitro for cytotoxicity activities against four tumor cell lines such as A549, MCF-7, Bel-7402, and Colo205. Compounds 3, 5 and 7 are found to show moderate cytotoxicity against the Bel-7402 cancer cell line.
