摘　　要：A novel pyrone derivative was isolated from the ethyl acetate extract of a culture broth of a strain of the fungus Cephalosporium sp. AL031. Its structure was characterized as 7-hydroxy-9-methoxyl-10-methyl-2H, 4all, 6H, 10bH-pyrano[5, 6-c][2]benzopyran-2, 6-dione by spectroscopic analysis including IR, MS, ID and 2D NMR spectra.A novel pyrone derivative was isolated from the ethyl acetate extract of a culture broth of a strain of the fungus Cephalosporium sp.
