Diversity of polyketides produced by Penicillium species isolated from Melia azedarach and Murraya paniculata

[摘要] Eight compounds comprising four groups of polyketides, the xanthone fusarindin, the mixed peptide alkaloid-polyketide GKK1032, the anthraquinones crisophanol, citreoveridin and janthinone, and the azaphylones dihydrocitrinone, citrinin and citrinin H-1, were identified in Penicillium species isolated as endophytic fungi from Melia azedarach and Murraya paniculata. The antibacterial activity of the azaphylones was tested and showed that citrinin H-1 is more active than citrinin.
