title: Cyathane diterpenoids and nitrogenous terphenyl derivative from the fruiting bodies of basidiomycete Phellodon niger.
abstract: Two new cyathane-type diterpenoids, nigernin A and B (1, 2), one new nitrogenous terphenyl derivative, phellodonin (3), together with three known compounds, 2',3'-diacetoxy-3,4,5',6',4''-pentahydroxy-p-terphenyl, grifolin, and 4-O-methylgrifolic acid, were isolated from the fruiting bodies of basidiomycete Phellodon niger. The structures of these new compounds were elucidated by spectroscopic methods and comparison with the data of known compounds in the literature. All these compounds were isolated from this fungus for the first time.
