摘要:
From the mycelium of Aspergillus terreus var. aureus, a new metabolite, gillusdin (1), was isolated. 1 was found to be 5, 7-dichloro-5, 6-dihydroxy-6-methoxy-4-methyl-3, 4-dioxospiro [benzofuran 2 (3H), 1-[2, 5] cyclohexadiene]-2-carboxylic acid methyl ester based on a 13C-NMR longrange selective proton decoupling (LSPD) experiment and other spectral data. Unlike the metabolites so far isolated from Aspergillus terreus, 1 is a new substance which seems to be biosynthesized via deoxyerythrolaccin as an intermediate.
