(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.
