title: Metabolites from Aspergillus versicolor, an endolichenic fungus from the lichen Lobaria retigera.
abstract: Three new anthraquinone derivatives (1-3) and one new artifact (4) were isolated, along with six known anthraquinone derivatives (5-10) and three xanthones (11-13), from a culture of an endolichenic fungus, Aspergillus versicolor, that was isolated from the lichen Lobaria retigera. The structures of these substances were determined on the basis of 1D and 2D (COSY, HMQC, and HMBC) NMR and MS analyses. The substances 1-4 were also tested for their cytotoxic activity.
