Chemical composition of the essential oil hydrodistilled from serbian taxus baccata L. / N. Radulović in The journal of essential oil research, Vol. 22 N° 5 (Septembre/Octobre 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 5 (Septembre/Octobre 2010) . - pp. 458-461 Titre : Chemical composition of the essential oil hydrodistilled from serbian taxus baccata L. Type de document : texte imprimé Auteurs : N. Radulović, Auteur ; P. Blagojević, Auteur ; R. Palić, Auteur Année de publication : 2011 Article en page(s) : pp. 458-461 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Taxus  baccata  Taxaceae  Essential  oil  composition  Hexahydrofarnesyl  acetone  Myrtenol Index. décimale : 646 Résumé : Hydrodistillation of fresh needles and branches of Taxus baccata L. (Gymnospermae, Taxaceae) yielded 0.02% (w/w) of the essential oil. GC and GC/MS analyses enabled the identification of 62 constituents that accounted for 92.2% of the total oil. The oil was found to mainly consist of components belonging to one of the following classes: terpenoids (28.2%), “green leaf” volatiles (12.0%), carotenoid derived compounds (18.4%) and n-alkanes (18.4%). The major contributors were hexahydrofarnesyl acetone (18.3%), myrtenol (18.3%), (Z)-3-hexenol (6.0%), 3-methyl-2-butenoic acid (5.9%) and tricosane (5.5%). The terpenoid fraction was completely made up of monoterpenoids and diterpenoids (mostly oxygenated derivatives), but, contrary to the oils isolated from other Taxus taxa, no sesqui-terpenoids were identifed.

Volatiles of the grape hybrid cultivar othello (Vitis vinifera x (Vitis labrusca x Vitis riparia)) cultivated in Serbia / N. Radulović in The journal of essential oil research, Vol. 22 N° 6 (Novembre/Décembre 2010)

Five major contributors were the following: heptacosane (15.0%), hentriacontane (15.0%), ethyl oleate (12.4%), nonacosane (11.0%) and pentacosane (8.3%). n-Alkanes (50.9%), fatty acid ethyl esters (32.2%) and higher aldehydes (7.7%) alone constituted 90% of the extract. Ethyl (E,Z)-2,4-decadienoate, ethyl hexacosanoate, ethyl tetracosanoate, ethyl docosanoate, octane and undecane are reported for the first time as grape constituents.
