Abstract

The endophytic fungus Penicillium glabrum was isolated from pomegranate fruits (Punica granatum) collected in Uzbekistan. Extracts of the fungus grown on rice yielded two new styrylpyrones, namely 3-methyldesmethoxyyangonin (1) and 3-methylbisnoryangonin (2), together with four known metabolites. The structures of the isolated compounds were elucidated on the basis of comprehensive spectral analysis (1D and 2D NMR and MS).
