Fund Project: The authors gratefully acknowledge the financial support from Scientific Research Foundation of the Education Department of Yunnan Province (03Y295A) and are grateful to Mr. Y. N. He, Ms. H. L. Liang in the State Key Laboratory of Phytochemistry and Plant Resources in West China, Kunming Institute of Botany, Chinese Academy of Sciences, for measuring NMR and MS data.

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, 4aH, 6H, 10bH-pyrano[5, 6-c][2]benzopyran-2, 6-dione by spectroscopic analysis including IR, MS, 1D and 2D NMR spectra.
