Chemical composition and antibacterial activity of the rhizome and leaf oils of amomum hypoleucum thwaites / Baby Sabulal in The journal of essential oil research, Vol. 19 N°3 (Mai/Juin 2007) 

Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°3 (Mai/Juin 2007) . - pp. 279-281 Titre : Chemical composition and antibacterial activity of the rhizome and leaf oils of amomum hypoleucum thwaites Type de document : texte imprimé Auteurs : Baby Sabulal, Auteur ; Rajani Kurup, Auteur ; Varughese George, Auteur Année de publication : 2007 Article en page(s) : pp. 279-281 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Amomum  hypoleucum  Zingiberaceae  Essential  oil  composition  Cryptone  β-pinene  (E)-nerolidol  α-fenchyl  acetate Résumé : Essential oils from the rhizomes and leaves of Amomum hypoleucum were hydrodistilled and characterized by GC/FID and GC/MS. Nineteen constituents comprising 93.0% were identified from the rhizome oil. Cryptone (15.4%), β-pinene (11.9%) and caryophyllene oxide (7.6%) were the major constituents in the rhizome oil. Fifty-two constituents comprising 97.6% were identified from the leaf oil. (E)-Nerolidol (26.5%), α-fenchyl acetate (15.0%) and β-caryophyllene (8.4%) were the major constituents in the leaf oil. These oils showed good antibacterial activity against the Gram-negative bacteria, Pseudomonas aeruginosa, Salmonella typhi and Escherichia coli.

Seventy-six constituents (98.5%) with β-caryophyllene (27.3%), α-humulene (13.8%) and α-copaene (11.5%) as major components were identifed from the leaf oil of M. malabarica. Also, seventy-six constituents (98.1%) with β-caryophyllene (23.4%), linalool (13.4%) and α-humulene (11.3%) as major constituents were identified from the leaf oil of G. canarica. Sesquiterpene hydrocarbons constituted 77.3% in M. malabarica leaf oil and 58.1% in G. canarica leaf oil.
