Abstract: Six dimeric naphthopyrones were isolated from the fermentation broth extract of Penicillium oxalicum, a fungus residing in Acrida cinerea. On the basis of spectral data and physicochemical properties,they were identified as secalonic acid A (1),asperpyrones A (2),asperpyrones B (3),asperpyrones C (4),asperpyrones D (5) and aurasperone A (6).All the compounds were isolated from the endophytic fungus of Penicillium oxalicum for the first time.Compounds 1 showed significant cytotoxic activity against Hep G2 with IC50 values of 1.1 μM.

Key words: Acrida cinerea, inset gut fungus, Penicillium oxalicum, cytotoxic activity
