Résumé
Wild Lepista inversa and L. flaccida were investigated for volatile constituents by gas chromatography-mass spectrometry (GC-MS). More than 40 compounds were identified with this technique from diethyl ether extracts as aliphatic alcohols, aldehydes and cetones as well as numerous aromatic compounds. Chlorinated compounds only detected in L. inversa clearly differentiated this species from L. flaccida. These secondary metabolites are of chemotaxonomic interest to identify these two related clitocyboid species.
