An α-pinene chemotype in salvia offcinalis L. (Lamiaceae) / Johannes Novak in The journal of essential oil research, Vol. 18 N° 3 (Mai-Juin 2006) 

Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° 3 (Mai-Juin 2006) . - pp. 239-241 Titre : An α-pinene chemotype in salvia offcinalis L. (Lamiaceae) Type de document : texte imprimé Auteurs : Johannes Novak, Auteur ; Marion Marn, Auteur ; Chlodwig M. Franz, Auteur Année de publication : 2006 Article en page(s) : pp. 239-241 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Salvia  offcinalis  Lamiaceae  Chemotype  Essential  oil  composition  Biosynthesis  α-pinene  Enantiomers  Segregation Résumé : Sage plants (Salvia offcinalis) were self-pollinated for three consecutive generations. The essential oil composition of 70 plants of the third generation, originating from four different mother plants, was analyzed. The content of α-pinene showed higher variation than all other compounds. The plants segregated into three distinct groups regarding the content of α-pinene: a low-level group around 2% α-pinene, a mid-level group around 9% and a high level group around 15%. This clear segregation into three groups proves the polymorphism (chemotype formation) of α-pinene in sage. Furthermore, the enantiomeric composition of α-pinene shifted from 35:65 [(−)-α-pinene:(+)- α-pinene] in the low level to 15:85 in the mid- and high level.

The essential oil composition of wild growing sweet marjoram (Origanum majorana L., Lamiaceae) from cyprus—three chemotypes / Johannes Novak in The journal of essential oil research, Vol. 20 n°4 (Juillet/Août 2008)

Franz, Auteur Année de publication : 2008 Article en page(s) : pp. 339-341 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Origanum  majorana  L.  Lamiaceae  Essential  oil  composition  Biosynthesis  Cis-sabinene  hydrate  Trans-sabinene  hydrate  Cis-sabinene  hydrate  acetate  α-terpineol Résumé : Individual plants grown in a greenhouse from seeds of a natural population of sweet marjoram (Origanum majorana L.) from Cyprus were analyzed for their essential oil composition. Three chemotypes were detected in the population. Besides the standard ‘marjoramy’ composition (‘sabinyl chemotype’) with 74% of oil compounds belonging to the bicyclic compounds sabinene, trans- and cis-sabinene hydrate and cis-sabinene hydrate acetate (‘sabinyl compounds’), two further chemotypes were present in the population, namely a pure α—terpineol chemotype (73% α—terpineol) and a mixed sabinyl/α—terpineol chemotype (41% sabinyl compounds, 40% α—terpineol). The chemotype frequencies found in this population were 56% of the plants belonging to the sabinyl chemotype, 4% to the pure α—terpineol chemotype and 40% to the mixed sabinyl/α—terpineol chemotype.
