【摘要】 多节孢属真菌代谢产物结构多样。该研究通过正相硅胶色谱、反相制备液相色谱等方法,从一株多节孢属真菌的固体发酵提取物中分离鉴定4个代谢产物,包括1个新化合物;根据理化性质和波谱数据,分别鉴定为2-羟基-1,1-二甲基-1,2,3,9-四氢-4H-咔唑-4-酮(1)、酪醇(2)、羟基酪醇(3)和羟基酪醇乙酸酯(4),其中1为新化合物。更多还原

【Abstract】 The genus Nodulisporium,is known to produce secondary metabolites with structural diversity. A new alkaloid,2-hydroxy-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.更多还原
