Volatile composition of Clitocybe amoenolens, Tricholoma caligatum and Hebeloma radicosum

Abstract : The volatile extracts composition of fresh Clitocybe amoenolens, Tricholoma caligatum and Hebeloma radicosum were analysed by Gas Chromatography-Mass Spectrometry. Twenty-one, sixteen and twenty-three components were identified, respectively. Methyl-(E)-cinnamate was found in the three analysed mushrooms at various amounts. Methyl-(E)-cinnamate and methyl-benzoate as well as (E)-nerolidol and methyl-anthranilate were the key odorants of C. amoenolens floral odor. Combined methyl-(E)-cinnamate and indole derivatives should largely contribute to the complex floral odor of T. caligatum with a nauseous note when aged; the latter volatiles could be of chemotaxonomic interest for the genus Tricholoma. Various aromatic derivatives (benzaldehyde, 2-phenylethanal, 2-phenylethanol, phenylacetic acid) were responsible for the almond-like odor with a floral note of Hebeloma radicosum.
