The genus Nodulisporium, is known to produce secondary metabolites with structural diversity. A new alkaloid, 2-hy- droxy-1,1-dimethyl-1,2,3,9-tetrahydro-4H-carbazol-4-one(1), was isolated from the extract of a fungal strain Nodulisporium sp. fermented with rice, together with three known phenols, tyrosol(2), hydroxytyrosol(3), and hydroxytyrosol acetate(4). Their structures were identified by detailed spectroscopic analyses.
