摘要

Chemical investigation of marine-derived fungus Humicola sp. GXIMD02070 has led to the isolation of a new sterigmatocystin derivative (1) and two known compounds 4-hydroxy-3,6-dimethyl-2-pyrone (2) and 2-(4-hydroxyphenyl)-ethanol (3). Their structures were elucidated by comprehensive analyses of the spectroscopic methods and quantum chemical calculation of NMR.
