Pers. harvested at four ontogenesis phases was analyzed by GC, GC/MS and 1H-NMR spectroscopy. More than 60 compounds were identified. Sesquiterpenoids constituted about 90% of the oil. Germacrene D (42.7–63.7%) and β-caryophyllene (9.0–15.9%) were the main constituents. The content of germacrene D increased until the flowering stage, however, the content of β-caryophyllene decreased at the same time.

Composition of the essential oil of ocimum sanctum L. grown in poland during vegetation / Agnieszka Kicel in The journal of essential oil research, Vol. 17 N° 2 (Mars-Avril 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 2 (Mars-Avril 2005) . - pp. 217-219 Titre : Composition of the essential oil of ocimum sanctum L. grown in poland during vegetation Type de document : texte imprimé Auteurs : Agnieszka Kicel, Auteur ; Anna Kurowska, Auteur ; Danuta Kalemba, Auteur Année de publication : 2006 Article en page(s) : pp. 217-219 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Ocimum  sanctum  Lamiaceae  Essential  oil  composition  Methyl  chavicol  l,8-cineole  β-bisabolene Résumé : The essential oils of the air-dried aerial parts of Ocimum sanctum L. (syn. O. tenuiflorum L.f.), harvested in four stages of vegetation, were isolated by hydrodistillation and analyzed by capillary GC, GC/MS, and 1H-NMR. The 57 compounds, representing 90–94% of the oil, were identified after oil distillation under reduced pressure and separation by repeated flash chromatography. The content of the main constituents: β-bisabolene (13–20%) 1,8-cineole (9–33%) and methyl chavicol (2–12%) varied during development of the plant.

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.
