Yadav, Auteur Année de publication : 2011 Article en page(s) : pp. 593-596 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Cinnamomum  tamala  Lauraceae  Essential  oil  composition  (E)-cinnamaldehyde  (3S)-(+)-linalool  (Z)-cinna-maldehyde Index. décimale : 646 Résumé : Variations and genuineness in constituents of Cinnamomum tamala leaf essential oil are characterized by enantio-GC-FID, capillary GC-FID and GC/MS. The oil samples were analyzed for two consecutive years. (E)-Cinnamaldehyde, which was the principal component, was higher in the first year oil samples but lower in the second year samples. Similarly, (Z)-cinnamaldehyde was 5.8–7.1% in the first year oils and 1–1.1% of the second year oils. Linalool content varied (6.4–8.5% and 5.7–16.2%, respectively) in first and second year oil samples, while (E)-cinnamyl acetate was higher (10.0–22.7%) in oil samples of the second year collection. Using a 10% heptakis(2,3-di-O-methyl-6-O-tert-butyldimethylsilyl)-b-cyclodextrin as the chiral stationary phase, optically pure (3S)-(+)-linalool was found in both the oil samples leading to complete enantiomeric excess for (3S)-(+)-enantiomer.

Linalool (23.6%), α-terpineol (3.8%), linalyl acetate (51.2%), β-caryophyllene (3.2%), germacrene D (1.3%) and sclareol (1.3%) were recorded in the oil S. sclarea cultivated in Lucknow UP while the Kashmir oil sample possessed the highest percentage of linalyl acetate (60.8%) and lowest linalool (14.5%) along with α-terpineol (1.8%), geranyl acetate (2.2%), β-caryophyllene (1.9%), germacrene D (2.6%) and sclareol (1.3%) as the other minor constituents. In contrast, the oil of S. sclarea from Purara in Uttarakhand showed highest percentage of linalool (29.8%), α-terpineol (5.3%) and sclareol (2.3%) and the lowest linalyl acetate (45.7%) among all the three samples. Further, high enantiomeric ratios ranged 76.8–79.5% for 3R-(-)-linalool and 78.8–99% for (-)-sclareol were determined on BETA DEX 110 capillary column.
