Headspace-SPME analysis of the sapwood and heartwood of picea abies, pinus sylvestris and larix decidua / Anna Wajs in The journal of essential oil research, Vol. 19 N°2 (Mars-Avril 2007)

More than 160 compounds were extracted and identified from spruce, pine, and larch stemwood. Differences in the quantitative and qualitative composition of the volatiles from the different conifer species were found. The volatile composition was specific for each species. Only small differences in the volatiles from different wood tissues, i.e. sapwood and heartwood, were found.

Volatile constituents of seeds of nigella orientalis cultivated in Poland / Anna Wajs in The journal of essential oil research, Vol. 22 N° 3 (Mai/Juin 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 3 (Mai/Juin 2010) . - pp. 232 - 234 Titre : Volatile constituents of seeds of nigella orientalis cultivated in Poland Type de document : texte imprimé Auteurs : Anna Wajs, Auteur ; Danuta Kalemba, Auteur Année de publication : 2010 Article en page(s) : pp. 232 - 234 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Nigella  orientalis  Essential  oil  composition  Volatiles  Hydrodistillation  HS-SPME Index. décimale : 646 Résumé : Volatile organic compounds from the seeds of Nigella orientalis L. were isolated by hydrodistillation and headspace- solid-phase microextraction (HS-SPME). Thirty compounds were identified, 16 of which were new for this plant material. The predominant group of components were sesquiterpene hydrocarbons, among which the major were: b-elemene, d-cadinene and a-selinene. By applying HS-SPME, it was possible to detect more compounds than by means of hydrodistillation. Sesquiterpene hydrocarbons were identified both in hydrodistilled essential oils and those analyzed using HS-SPME, while monoterpenes and low boiling non-terpenes were detectable only by means of HS-SPME method.
