Three new polyketides, cyathuscavins A (1), B (2), and C (3) were isolated from the mycelium culture of Cyathus stercoreus. The structures of the compounds were elucidated on the basis of NMR and mass spectroscopic data. Antioxidant activities of the compounds were evaluated by the scavenging ability against ABTS+, DPPH, and superoxide anion radicals. Cyathuscavins A–C showed significant antioxidant activity comparable to those of reference antioxidants, BHA and Trolox. Cyathuscavins A–C protected supercoiled plasmid DNA from Fe2+/H2O2-induced breakage.
