Titre : Chemical composition of the essential oil of microtoena patchoulii [(C.B. Clarke Ex J.D. Hooker) C.Y. Wu et Hsuan] Type de document : texte imprimé Auteurs : Manami Senpuku, Auteur ; Kazuya Nonaka, Auteur ; Michiho Ito, Auteur Année de publication : 2007 Article en page(s) : pp. 336-337 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Microtoena patchoulii Lamiaceae Essential oil composition Patchouli alcohol 1-octen-3-ol Résumé : The chemical components of the essential oil obtained from the steam-distillation of Microtoena patchoulii leaves were investigated by GC and GC/MS, and twenty-one compounds were identified. The major compounds of the oil were patchouli alcohol (54.4%), 1-octen-3-ol (21.4%), and α-guaiene (2.4%). The composition of M. patchoulii oil is similar to that of commercial patchouli oil, and similar pharmacological effects could be expected when it is used as a substitute for Pogostemon cablin.

Titre : Induction of sesquiterpenoid production by methyl jasmonate in aquilaria sinensis cell suspension culture Type de document : texte imprimé Auteurs : Michiho Ito, Auteur ; Ken-ichiro Okimoto, Auteur ; Toru Yagura, Auteur Année de publication : 2006 Article en page(s) : pp. 175-180 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Aquilaria sinensis Thymelaeaceae Agarwood Methyl jasmonate Solid phase micro-extraction Cell culture Ses-quiterpenoid production Résumé : A suspension cell culture was established from Aquilaria sinensis, a timber species producing fragrant woody material called “Agarwood.” Methyl jasmonate was added to this culture in order to induce production of fragrant compounds. Cells were harvested after seven days of incubation and subjected to solid phase micro-extraction to produce an extract that was analyzed by GC/MS. Three peaks appeared on GC and were identifi ed as α-guaiene, γ-guaiene (= 1(10),11-guaiadiene), and α-humulene based on their mass fragmentation patterns and 13C-NMR data. The production of the guaiene derivatives and α-humulene showed different kinetics, which may mean they are the products of different induced biosynthetic enzymes.

Titre : Sedative effect of vapor inhalation of essential oil from heracleum afghanicum kitamura seeds Type de document : texte imprimé Auteurs : Abdul Ghani Karimi, Auteur ; Michiho Ito, Auteur Année de publication : 2014 Article en page(s) : pp. 571-577 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Heracleum afghanicum Apiaceae Essential oil composition Vapor inhalation Sedative effect Aliphatic esters Hexyl butyrate Octyl acetate Résumé : Heracleum afghanicum (Apiaceae) is a perennial plant indigenous to Afghanistan. Phytochemical and pharmacological analyses of H. afghanicum seeds essential oil were carried out to investigate its possible sedative effects on mice spontaneous locomotor activity. The essential oil was analyzed by gas chromatography (GC) and GC/mass spectrometry (GC/MS), and thirty-three constituents were identified. Hexyl butyrate (34.3%) and octyl acetate (21.1%) were found as its principal constituents. The sedative effect of H. afghanicum essential oil was confirmed using an open field test with ddY mice. The essential oil significantly decreased the locomotor activity of mice, suggesting its sedative effect. Hexyl butyrate and octyl acetate were found to be responsible for the sedative activity of H. afghanicum seeds essential oil.
