| Abstract: | Three isocoumarin compounds (BV 1, 2 and 3) were isolated from the cultural broth of Aspergillus oniki 1784. BV 1 was mellein (3-methyl-8-hydroxy-3,4-dihydroisocoumarin). BV 2 and 3 were assigned to be 3-methyl-4,8-dihydroxy-3,4-dihydroisocoumarin, 3-methyl-3,8-dihydroxy-3,4-dihydroisocoumarin, respectively. These two compounds (BV 2, 3) were newly isolated. Also another component named BV 4 was proved to be 6-methylsalicylic acid. |
