Titre : Chemodiversity or taxonomy error? A search for the true phytochemical profile of Ferula arrigonii Bocchieri Auteurs : Louis-Félix Nothias, Mauro Ballero, Andrea Maxia, Federica Pollastro, Pieter Dorrestein, Julien Paolini, Marc Litaudon, Giovanni Appendino, Revue : Phytochemistry Numéro : Issue 1 Volume : 1 Date : 2018/02/23 DOI : ISSN : Résumé : The guaianolide 11,13-dehydrogrilactone (2) was previously described as alleged chemotaxonomic marker of the Sardo-Corsican endemic species Ferula arrigonii Bocchieri. In the present work, the presence of this component could not be confirmed in various extracts obtained from plants harvested in Sardinia and Corsica island as well as in its vegetal material from reference herbarium species. All studied samples of F. arrigonii showed a homogenous phytochemical profile characterized by sesquiterpene coumarin ethers. These results suggest that the previous investigations have probably been carried out on plant material corresponding to an atypical niche chemotype or, alternatively, that they resulted from an erroneous identification.
