Talaroxanthone, a novel xanthone dimer from the endophytic fungus Talaromyces sp. associated with Duguetia stelechantha (Diels) R. E. Fries

DgCr22.1b, an endophytic isolate of Talaromyces sp., was collected in the Amazonian Rainforest from the medicinal plant Duguetia stelechantha. From the fractionation of the methanolic mycelial extract, a new xanthone dimer talaroxanthone was isolated. The structure of this new compound was elucidated based on spectroscopic analyses including 2D nuclear magnetic resonance (NMR) experiments.
