The fruiting bodies of fresh and wild Clitocybe odora, Lentinellus cochleatus and Agaricus essettei were investigated for volatile compounds by gas chromatography-mass spectrometry analysis using hydro-distillation and solvent extraction techniques. The three mushroom species are well known to possess anise odors. The main volatile compounds of the three species were aromatic derivatives. Anise fragrance was due either to a single impact aroma compound, or to mixtures of volatile constituents. p-Anisaldehyde was identified as the key odorous component responsible for the pure anise fragrance of C. odora. p-Anisaldehyde, methyl p-anisate, methyl (Z)-p-methoxycinnamate and methyl (E)-p-methoxycinnamate were responsible for the aniseed smell of L. cochleatus. Benzaldehyde and benzyl alcohol may contribute to the anise-like odor of A. essettei.
Key words: Anisaldehyde, Basidiomycota, fruiting bodies, natural fragrance
