Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 3 (Mai/Juin 2011) . - pp. 55-57 Titre : Chemical analysis of essential oil from the leaves of eugenia argentea Bedd. Type de document : texte imprimé Auteurs : Gopan Raj, Auteur ; Varughese George, Auteur ; Mathur G. Sethuraman, Auteur Année de publication : 2011 Article en page(s) : pp. 55-57 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Eugenia  argentea  Myrtaceae  Leaf  oil  composition  β-caryophyllene  δ-cadinene  Germacrene-D Index. décimale : 646 Résumé : The essential oil obtained by hydrodistillation of the leaves of Eugenia argentea was analyzed by GC and GC/MS. Thirty-five constituents comprising 98.5% of the oil were identified. The leaf oil was characterized by the abundance of three major classes of sesquiterpenoids, viz. caryophyllanes, cadinanes and germacranes. β-Caryophyllene (18.0%), δ-cadinene (7.8%) and germacrene-D (7.1%) were the major constituents in the leaf oil. No monoterpenes were detected in the leaf oil.

Twenty components comprising 80.3% of the leaf oil, twenty-six components comprising 94.7% of the bark oil and twenty-seven components comprising 78.8% of the fruit oil were identified. The major components in the leaf oil were caryophyllene oxide (33.0%) followed by selin-11-en-4α-ol (14.8%). The bark oil contained 10.2% cadinene and two isomers of cadinol viz. α-cadinol (24.5%) and α-muurolol (22.2%) as the major components, while the fruit oil had α-cadinol (19.9%) and caryophyllene oxide (13.7%) as the major components. The fruit, leaf and bark oils showed moderate to good activity against some of the tested Gram-positive and Gram-negative bacteria.
