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.
