| Abstract: | Two isofuranonaphthoquinone derivatives, named arthoniafurones A (1-acetyl-8-hydroxynaphtho2,3-c]furan-4,9-dione) and B 1-acetyl-4,8-dihydroxynaphtho2,3-c]furan-9(4H)-one], were isolated from a spore-derived culture of the mycobiont of the lichen Arthonia cinnabarina, that is new to Japan. Bostrycoidin and 8-O-methylbostrycoidin were also identified in the A. cinnabarina culture. |
