Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°5 (Septembre/Octobre 2007) . - pp. 403-406 Titre : Chemical composition of leaf and inflorescence essential oils of eupatorium cannabinum L. from eastern Lithuania Type de document : texte imprimé Auteurs : Asta Judzentiene, Auteur Année de publication : 2007 Article en page(s) : pp. 403-406 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Asteraceae  Eupatorium  cannabinum  Essential  oil  composition  Germacrene  D  Neryl  acetate  Methyl  thymol Résumé : Content and composition of the essential oils of Eupatorium cannabinum L. have been studied. The plants were collected on Neris riverbank in Vilnius district at full flowering stage; oils were prepared by hydrodistillation and analyzed by GC and GC/MS. Germacrene D has been found as a first principal component in five out of six investigated oils (9.1–12.3%) and in one flower oil as third main compound (7.7%). Neryl acetate was a second major constituent in all leaf oils (average mean: 9.4%) and in two samples of in florescence oils (7.9% and 8.2%), while another ester neryl isobutyrate was the third dominant component in one flower oil. Methyl thymol was the first main compound in one flower oil and the fourth in all investigated leaf oils (average mean: 5.7%). β-Bisabolene comprising 7.1% and 5.6% was second or fourth constituent in two in florescence, and as third compound (6.7% and 8.6%) in two leaf oils. Seventy-nine identified compounds formed up 71.9–83.8% of total oil content. Monoterpenes and oxygenated monoterpenes dominated both in the in florescence and leaf oils (36.9–59.3% and 36.5–44.3%, respectively), while the amount of sesquiterpenoids was 22.7–31.8% in the flower and 31.7–38.3% in leaf oils.

Chemical composition on essential oils from needles of pinus sylvestris L. grown in northern lithuania / Asta Judzentiene in The journal of essential oil research, Vol. 20 N°1 (Janvier/Fevrier 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 N°1 (Janvier/Fevrier 2008) . - pp. 26-29 Titre : Chemical composition on essential oils from needles of pinus sylvestris L. grown in northern lithuania Type de document : texte imprimé Auteurs : Asta Judzentiene, Auteur ; Eugenija Kupcinskiene, Auteur Année de publication : 2008 Article en page(s) : pp. 26-29 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Pinus  sylvestris  Pinaceae  Essential  oil  composition  α-pinene  δ-3-carene  β-caryophyllene  δ-cadinene  α-cadinol  Epi-α-cadinol  Epi-α-muurolol  α-muurolol  Seasonal  variation Résumé : Content and composition of needle essential oils of Pinus sylvestris (Scots pine) grown in the north of Lithuania have been studied. Volatile components of dried current-year and 1 year old needles were extracted by simultaneous hydrodistillation-extraction and analyzed by GC and GC/MS. The most predominant fraction was found to be monoterpene hydrocarbons (26.4–41.3%), with the major constituents α-pinene (7.0–16.1 %) and δ-3-carene (5.2–14.3 %) in it. Among the oxygenated monoterpenes bornyl acetate was the most dominant constituent (1.1–3.9 %). Sesquiterpene hydrocarbons formed 19.4–26.0 % of the oils; amounts of main sesquiterpenes β-caryophyllene and δ-cadinene were 2.6–5.8 % and 2.3–5.9 %, respectively. α-Cadinol (4.2–8.5 %) and epi-α-cadinol with epi-α-muurolol and α-muurolol (4.0–9.1 %) were the major compounds in oxygenated sesquiterpenes fraction. Diterpenoids (including and tentitatively identified compound) comprised 6.2–13.7 % of the oils. Also, differences in composition of current-year and 1 year old needles were represented in the study. Seventy-one identified component made up 89.1–98.2 % of total oil content. One sample of fresh needles was analyzed in order to compare the composition with oils obtained from dried needles. Relative amount of monoterpene hydrocarbons was significantly higher (71.0 %) in the oil of fresh needles.

Composition of inflorescence and leaf essential oils of achillea millefolium L. with white, pink and deep pink flowers growing wild in vilnius (Eastern Lithuania) / Asta Judzentiene in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005)

Essential oils were produced by hydrodistillation and analyzed by GC and GC/MS. The main constituents of the inflorescence oils were β-pinene (13.1–19.3%), (E)-nerolidol (7.0–16.1%), piperitone (10.8%, deep pink inflorescences), β-eudesmol (8.4%, white), β-caryophyllene (6.7%, pink) and these of leaf oils—β-eudesmol (12.8%, white flowering plant), borneol (10.7%, pink), piperitone (10.0%, deep pink), caryophyllene oxide (6.4–10.4%), selin-11-en-4a-ol (6.5–7.5%) and spathulenol (6.1%, pink). The amounts of β-pinene decreased and (E)-nerolidol increased in the inflorescence oils with intensity of yarrow fl owers color. The inflorescences with different colored flowers produced markedly higher amounts of sabinene, β-pinene, 1,8-cineole, γ-terpinene, β-caryophyllene, α-humulene and (E)-nerolidol than leaves. The above correlation was identified for mono- and sesquiterpene hydrocarbons. An opposite correlation was determined for spathulenol, caryophyllene oxide, β-eudesmol, selin-11-en-4α-ol and oxygenated sesquiterpenes. Fifty-two identified compounds made up 93.0–96.6% of the inflorescence oils and 69.2–74.1% of leaf oils.
