Bioactive metabolites from the endophytic fungus Ampelomyces sp. isolated from the medicinal plant Urospermum picroides

Extracts of the fungal endophyte Ampelomyces sp. yielded 14 natural products out of which six (macrosporin-7-O-sulfate, 3-O-methylalaternin-7-O-sulfate, ampelopyrone, desmethyldiaportinol, desmethyldichlorodiaportin, and ampelanol) were compounds. The known macrosporin and 3-O-methylalaternin were also identified in the host plant Urospermum picroides, indicating that they are also produced by the endophyte in planta.
