Their constituents were identified using GC, GC/MS, 1H- and 13C-NMR. Fifty-six compounds were identified in both essential oils that consisted mainly of bifunctional thymol derivatives and sesquiterpene hydrocarbons. 10-Isobutyryloxy-8,9-didehydro-thymol isobutyrate and 10-isobutyryloxy-8,9-didehydro thymol methyl ether were the main components of both essential oils.

Identification of volatile constituents in flowers and leaves of trifolium repens L. / A. Kicel in The journal of essential oil research, Vol. 22 N° 6 (Novembre/Décembre 2010)

Type de document : texte imprimé Auteurs : A. Kicel, Auteur ; M. Wolbis, Auteur ; D. Kalemba, Auteur Année de publication : 2011 Article en page(s) : pp. 624-627 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Trifolium  repens  Fabaceae  Essential  oil  composition  1-octen-3-ol Index. décimale : 646 Résumé : The chemical composition of the volatile components obtained by two different methods (SDE, HS-SPME) from flowers and leaves of Trifolium repens L. grown in Poland was determined by GC and GC/MS. Depending on the isolation method used, 75 compounds (71–80% of the oils) contained in the flowers and 63 compounds (80–82%) derived from the leaves were respectively identified. The principal volatile constituents in the SDE extract from the flowers were hexahydrofarnesyl acetone (6.2%), 4-vinylguaiacol (4.5%), (E)-2-heptenal (3.0%) and 2-phenylethanol (3.0%), whereas in the SPME were 1-octen-3-ol (10.6%), 2-phenylethanol (7.3%), linalool (5.5%), benzaldehyde (4.6%) and (E)-2-heptenal (3.8%). The most abundant volatile constituents detected in the SDE extract from the leaves were 1-octen-3-ol (15.1%), (E)-2-hexenal (9.3%), (E)-2-heptenal (6.1%), 4-vinylguaiacol (4.1%) and carvone (3.4%), whereas in the SPME were 1-octen-3-ol (17.7%), carvone (10.7%), limonene (8.5%), (E)-β-ionone (5.9%), 2-phenylethanol (5.1%) and β-ionone epoxide (4.4%).
