JOINT OCCURRENCE OF A LICHEN DEPSIDONE AND ITS PROBABLE DEPSIDE PRECURSOR.
A chemical race of the lichen Cetraria ciliaris Ach., known to produce the depside olivetoric acid, contains the corresponding depsidone, physodic acid, as well. Physodic acid may form by an intramolecular coupling of olivetoric acid.
