Abstract

The endophytic fungus Epicoccum nigrum was isolated from sugarcane and the bioguided fractionation of the ethyl acetate extract led to the isolation of epicolactone, mellein, and 4,5-dimethylresorcinol. Characterization of epicolactone by MS, NMR and X-ray crystallography revealed a new natural product with an unusual carbon skeleton. The production of this secondary metabolite decreased in mutants of Epicoccum nigrum transformed by Agrobacterium tumefaciens. Additionally, these mutants produced 4-hydroxymellein. (AU)
