A NEW BIPHENYL DERIVATIVE FROM AN UNIDENTIFIED MARINE FUNGUS E33

摘要

A new biphenyl derivative 3,5'-dihydroxy-4',-5-dimethoxy-2'-methyl-[1,1'-biphenyl]-2-carboxylic acid methyl ester (1), was isolated from the culture broth of a fungus isolated from the rhizosphere soil of mangrove root on the South China Sea. The structure of 1 was determined by comprehensive spectroscopic methods, primarily 2D NMR techniques.
