Abstract
A phenolic derivative, atraric acid, was identified by GC/MS and quantified by GC/MS/MS in the outer parts of wood from oaks specifically colonised by lichens. This compound was correlated to the presence of a bitter depside, atranorin, which is a natural metabolite of the lichen species belonging to the genus Parmelia.

Key words: Lichens / atranorin / atraric acid / oak wood / ion trap mass spectrometry / quantification.
