Abstract

A novel dimeric naphtho-gamma-pyrone, named aurasperone F (1), was isolated from the fermentation broth of the culture extracts of Aspergillus niger C-433, isolated from grapes, along with the known compounds fonsecin (2), aurasperone B (3), aurasperone C (4), aurasperone D (5) and aurasperone E (6). The chemical structure of the new natural product was established by extensive one- and two-dimensional NMR spectroscopic studies (1H, 13C, COSY, HMQC, 1D NOE spectra), as well as on the UV, MS and IR spectral analysis.
