Type de document : texte imprimé Auteurs : Gopan Raj, Auteur ; Varughese George, Auteur ; Nediyaparambil S. Pradeep, Auteur Année de publication : 2008 Article en page(s) : pp. 72-74 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Syzygium  gardneri  Myrtaceae  Essential  oil  composition  Caryophyllene  oxide  Antimicrobial  activity Résumé : Essential oil from the leaves of Syzygium gardneri was isolated by hydrodistillation and analyzed by GC and GC/MS. Twenty compounds representing 88.8% of the oil were identified. The major constituent in the oil was caryophyllene oxide (49.6%). Monoterpenes were detected in low percentage (1.2%). The oil was tested for antimicrobial activity against Gram-positive and Gram-negative bacteria as well as against the fungi Candida albicans and C.glabrata.

Pradeep, Auteur Année de publication : 2008 Article en page(s) : pp. 588-590 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Eugenia  rottleriana  Myrtaceae  Essential  oil  composition  Limonene  α—humulene  β—caryophyllene  Antibacterial  activity Résumé : Essential oil obtained by hydrodistillation from the leaves of Eugenia rottleriana was analyzed by GC and GC/MS. Twenty-eight compounds constituting 99.1% of the analyzed sample were identified. The oil was characterized by the predominance of monoterpenes (61.2%) with limonene (50.3%) as the major constituent. α—Humulene (13.3 %), β—caryophyllene (8.8%) and linalool (3.2%) were the other major components. The oil displayed significant antibacterial activity when tested against Bacillus cereus and moderate activity against Serratia marcescens and Escherichia coli.
