Titre : Chemical composition and antimicrobial activity of the essential oil of Curcuma leucorhiza Roxb Type de document : texte imprimé Auteurs : Langoljam R. Devi, Auteur ; Virendra S. Rana, Auteur ; Sarangthem I. Devi, Auteur Année de publication : 2014 Article en page(s) : pp. 533-538 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Curcuma leucorhiza Zingiberaceae Germacrone Curdione Antimicrobial activity Résumé : The essential oils obtained by hydrodistillation from the rhizomes and leaves of Curcuma leucorhiza Roxb. were analyzed by gas chromatography (GC) and GC/mass spectrometry (GC/MS) for the first time. A total of forty-nine compounds were identified in both oils. The main compounds in the rhizome and leaf oils were germacrone (9.6–19.7%), curdione (19.1–19.5%), camphor (7.2–8.1%), 1,8-cineole (4.0–7.4%), curzerene (3.0–5.7%), linalool (5.2–5.4%), neo-curdione (2.8–4.6%) and isoborneol (2.0–3.8%). Screening of the essential oils showed promising antibacterial activity (7–16 mm inhibition zone) against Streptococcus mutans, Pseudomonas putida, Bacillus subtilis, Klebsiella pneumoniae and antifungal activity (9–14 mm inhibition zone) against Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger and Candida albicans at 20 μg/disc of the oil by disc diffusion method as compared with standards.

(Lauraceae) were collected from seven plants occurring in seven different areas of Manipur and analyzed for their essential oil and eugenol contents using GC and GC/MS.
The yield of the oil was found to vary from 1.5–5.6% (w/w), on a dry weight basis.
A total of 79 compounds were identified in the oils.
Eugenol was found as a major compound in the leaf oils and its concentration varied from 35.1–94.3% followed by α-phellandrene (1.0–25.4%).DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Variation of terpenoids constituents in natural population of cinnamomum tamala (L.) leaves [texte imprimé] / Virendra S.
