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.
