New Findings from the Volatiles of the Corsican Liverwort : An Evaluation of Their Allelopathic Effect.

The volatile metabolites of the Corsican liverwort and their allelopathic implication were studied for the first time. Volatile compounds of the essential oil, hydrosol, and ether extract were investigated using gas chromatography (GC), GC-mass spectrometry, and nuclear magnetic resonance. Drimane and pinguisane derivatives were dominant in the plant.
