Koch from different European countries were determined using capillary GC and GC/MS methods. The oils were obtained in yields of 0.11–1.80% from dried cut roots and 0.09% from leaves. A total of 48 components were identified, representing over 87% of the total yield of oil. Ten compounds not earlier reported: trans-p-mentha-2,8-dien-1-ol, iso-thujyl alcohol, p-mentha-1,5-dien-8-ol, bicyclo[3.2.0]heptan-3-ol, 2-methylene-6,6-dimethyl, trans-carveol, perillaldehyde, sabinyl acetate, perillyl alcohol, methyl ester of methylpentadecate acid, and methyl hexadecadienate acid. The principal components in the oils of L. officinale roots were β-phellandrene (0.1–48.9%), pentylcyclohexadiene (0–12.3%), trans-sabinyl acetate (0–12.1%), α-terpinyl acetate (0–26.1%), (Z)-3-butylidene phthalide (0.1–31.2%), and (Z)-ligustilide (0.2–70.9%). Phthalide isomers were predominant (73.2–82.6%) in the oils from Estonia, France, and Belgium. The roots oil of L. officinale from Scotland was rich in β-phellandrene (48.9%) and phenylacetaldehyde (17.2%). Maximum content of trans-sabinyl and α-terpinyl acetates (total 38.2%) was found in the oil from Holland. Estonian L. officinale root oil contained in high quantities (E)-ligustilide (52.4–70.9%) and pentylcyclohexadiene (12.3%). The L. officinale leaf oil cultivated in Estonia contained in high amounts α-terpinyl acetate (55.8%) and β-phellandrene (11.3%). The content of (Z)-ligustilide (17.0%) in the leaf oil was smaller compared with the root oil.

Extracts were analyzed using GC/FID and GC/MS methods. Sixty compounds were identified representing over 90% of the oil, of which 1,8-cineole (25.7%) and α-pinene (20.6%) were the major components. Two flavonoid compounds were identified in SFE extracts. The composition of SFE extracts under mild conditions did not have great distinctions compared with SDE.

The content and composition of the essential oil Found in Carum carvi L. commercial fruits obtained from different countries / Ain Raal in The journal of essential oil research, Vol. 24 N° 1 (Fevrier 2012) 

Public ISBD [article]  in The journal of essential oil research > Vol. 24 N° 1 (Fevrier 2012) . - pp. 53-59 Titre : The content and composition of the essential oil Found in Carum carvi L. commercial fruits obtained from different countries Type de document : texte imprimé Auteurs : Ain Raal, Auteur ; Elmar Arak, Auteur ; Anne Orav, Auteur Année de publication : 2012 Article en page(s) : pp. 53-59 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Carum  carvi  Caraway  Apiaceae  Essential  oil  Carvone  Limonene  European  Pharmacopoeia Résumé : Caraway (Carum carvi L., Apiaceae) is a very popular spice and herb, which is widely applied in the food and pharmaceutical industry. Variations in the essential oil content and composition in twenty commercial caraway samples obtained from retail pharmacies and health shops in different countries were determined using hydrodistillation and capillary GC techniques. The essential oil yields ranged from 0.6% to 5.4%. Eighteen compounds, comprising more than 97% of the composition of oil, were identified in the caraway essential oils. The main components of the oils in caraway seeds were carvone (44.5–95.9%) and limonene (1.5–51.3%). Between the content of carvone and limonene the negative correlation -0.999 (p<0.01) was found. Additionally, β-myrcene (0–0.4%), trans-dihydrocarvone (0–0.5%), and trans-carveole (0–0.2%), as well as α-pinene, sabinene, n-octanal, trans-β-ocimene, γ-terpinene, linalool, cis- and trans-limonene oxide, cis-dihydrocarvone, cis-carveol, perillaldehyde, trans-anethole, and trans-β-caryophyllene were found in caraway oils. The content and composition of the essential oils in commercial caraway seeds is remarkably variable and conformed with the European Pharmacopoeia standards only in four samples among the 20 commercial caraway samples studied. The carvone and carvone-limonene chemotypes were found.

Valerianae radix samples were obtained from retail pharmacies of different European countries. The roots of 15 V. offcinalis samples yielded 0.19–1.16% essential oil on a dry weight basis. The basic oil components among the identified 86 compounds were bornyl acetate (2.9–33.7%), α-fenchene (0–28.3%), valerianol (0.2–18.2%), valerenal (tr-15.6%), isovaleric acid (0–13.1%), camphene (0–11.1%) and valeranone (0.5–10.9%). Bornyl acetate/valerenal chemotype was characteristic for 9 of the 15 samples of valerian roots from different European countries. Some samples did not contain α-fenchene and camphene (Germany, Czech), isovaleric acid (France, Moldova, Russia 2) and valerianic acid (Estonia, Ukraine 1, Scotland, Moldova, Russia 1). Valerian root oil from Estonia was rich in essential oil, bornyl acetate (33.7%), valerianol (16.8%) and valeranone (9.5%).
