Abstract
One known (1) and five new polyketide metabolites (2-6) were isolated from the culture extract of an endophytic fungus. Mycelia sterila, from the Canadian thistle Cirsium arvense. Compounds 1-4 are members of the isocoumarin family, whereas metabolite 5 is a dihydrobenzofuran and 6 has an open chain structure. All compounds have an unusual methyl group at the aromatic ring that does not fit into the usual polyketide pattern.Keywords
