Chanotiya, Auteur ; C. S. Mathela, Auteur Année de publication : 2006 Article en page(s) : pp. 408-409 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Valeriana wallichii Valerianaceae Essential oil composition 3-methylvaleric acid Maaliol Résumé : The leaf and root oils of Valeriana wallichii DC, native to Northwestern Himalaya, were investigated by GC and GC/MS. Twenty and 23 components were identifi ed in the leaf and root oil constituting about 83.2% and 89.3% of the oils, respectively. 3-Methylvaleric acid (26.5%) and maaliol (39.2%) were the major constituents of the leaf oil. The root oil was also rich in maaliol (64.3%) and β-gurjunene (7.2%). ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2005.9698945#.Ucg9hmF2_n4

Titre : Effect of seasons and drying on the essential oil composition of leaf in ocimum kilimandscharicum guerke Type de document : texte imprimé Auteurs : Narendra Kumar, Auteur ; Rajani Shukla, Auteur ; C. S. Chanotiya, Auteur Article en page(s) : pp. 400-402 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Ocimum kilimandscharicum Lamiaceae Essential oil composition Camphor 1,8-cineole Drying effect Index. décimale : 646 Résumé : The effect of seasons (winter and summer) and drying on the yield and composition of essential oil obtained from the leaves of Ocimum kilimandscharicum, cultivated at the subtropical conditions of North India, was examined by combined GC and GC/MS analysis.
This chemotype was found to be rich in camphor (winter 48.9%, summer 58.9%), 1,8-cineole (winter 22.2%, summer 14.8%), and limonene (winter 5.5%, summer 5.6%).
The yield of oil was observed to be more in summer (0.8%) than in winter (0.6%).
On shade drying of the leaves, no effect was observed in the yield of oil in winter season.
However, in summer, yield was slightly reduced on drying (from 0.8% to 0.6%).
Camphor, the major constituent of the oil, showed slight degradation in quantity during drying in both winter and summer seasons.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top

Titre : Enantioenriched (3S)-(+)-linalool in the leaf oil of cinnamomum tamala nees et eberm. from Kumaon Type de document : texte imprimé Auteurs : C. S. Chanotiya, Auteur ; A. 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.
