Essential oil of eaglewood tree / Phatik Tamuli in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 6 (Novembre-Décembre 2005) . - pp. 601-604 Titre : Essential oil of eaglewood tree : A product of pathogenesis Type de document : texte imprimé Auteurs : Phatik Tamuli, Auteur ; Paran Boruah, Auteur ; Subhan C. Nath, Auteur Année de publication : 2006 Article en page(s) : pp. 601-604 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Aquilaria  agallocha  Chaetomium  globosum  Fusarium  oxysporum  Thymelaeaceae  Essential  oil  composition  Hexadecanoic  acid Résumé : The essential oil of eaglewood tree (Aquilaria agallocha Roxb.) has been considered to be a pathological product. An investigation was carried out to study the difference in composition of oils obtained from healthy, naturally infected and artificially inoculated eaglewood using GC and GC/MS analyses. This investigation showed a marked difference in the oil compositions among the treatments with regards to their quality. Valerianol (3.0%) and tetradec-anioc acid (7.1%) contents were recorded higher in the oils of naturally infected plants than in that of healthy ones (0.1% and 6.9%, respectively). Pentadecenoic acid was totally absent in the oils of healthy, whereas it was found in a greater amount (6.8%) in the oil of naturally infected plants. In contrast, dodecanoic acid (3.1%), pentadecanoic acid (6.2%), hexadecanoic acid (31.5%) and octadecanoic acid (4.1%) were found in a higher amount in the oils of healthy plants, while the oils obtained from naturally infected plants contained lower amounts of these components (2.5%, 4.8%, 20.0% and 1.0%, respectively). The oils obtained from the inoculated plants showed almost similar distribution of the components with healthy plants.

Thirty-six and 15 components representing 67.8% and 98.7% of the total oils of C. glanduliferum and C. glaucescens, respectively, were identified. (E)-Nerolidol (52.2%) was the major component in C. glanduliferum, while elemicin (92.9%) was the predominant component in C. glaucescens. The occurrence of (E)-nerolidol (52.2%) and elemicin (92.9%) as a major component in the leaf oils of C. glanduliferum and C. glaucescens, respectively, are reported here for the first time in this genus. These results of comparisons with those previously reported for the same plant parts revealed that C. glanduliferum leaf oil is a chemotype source for (E)-nerolidol, while C. glaucescens leaf oil is a new source of elemicin.
