Composition and antimicrobial activity of essential oil of ferulago longistylis boiss. fruits / Ayse Mine Gençler Özkan in The journal of essential oil research, Vol. 20 n°6 (Novembre/Décembre 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 n°6 (Novembre/Décembre 2008) . - pp. 569-573 Titre : Composition and antimicrobial activity of essential oil of ferulago longistylis boiss. fruits Type de document : texte imprimé Auteurs : Ayse Mine Gençler Özkan, Auteur ; Betül Demirci, Auteur ; Fatih Demirci, Auteur Année de publication : 2009 Article en page(s) : pp. 569-573 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Ferulago  longistylis  Apiaceae  Essential  oil  composition  2,3,6-trimethylbenzaldehyde  α-pinene  (Z)-β-ocimene  Antimicrobial  activity Résumé : The essential oil from the fruits of Ferulago longistylis Boiss. (Apiceae) was obtained by hydrodistillation. Simultaneous analyses by GC and GC/MS resulted in the identification of 59 compounds representing 96% of the essential oil. The major constituents found were 2,3,6-trimethylbenzaldehyde (29%), α-pinene (17%), (Z)-β-ocimene (16%), sabinene (6%), myrcene (6%) and bornyl acetate (4%). The oil was also screened for its antimicrobial properties against various Gram negative (Bacillus cereus, Enterobacter aerogenes, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhimurium) and Gram positive (Staphylococcus epidermidis, S. aureus, methicilline resistant S. aureus) bacteria and the yeast Candida tropicalis. Using a broth microdilution assay, only moderate to weak inhibitory activity (0.5–1 mg/mL) was observed against the microorganisms screened in this assay when compared to the standard antimicrobial agents.

Volatiles of hypericum bupleuroides griseb. / Fatih Demirci in The journal of essential oil research, Vol. 18 N° 6 (Novembre-Décembre 2006) 

Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° 6 (Novembre-Décembre 2006) . - pp. 650-651 Titre : Volatiles of hypericum bupleuroides griseb. Type de document : texte imprimé Auteurs : Fatih Demirci, Auteur ; K. Hüsnü Can Başer, Auteur Année de publication : 2006 Article en page(s) : pp. 650-651 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hypericum  bupleuroides  Guttiferae  Microdistillation  Essential  oil  composition  β-caryophyllene  β-sesquiphellandrene Résumé : Hypericum bupleuroides Griseb. (Guttiferae) was collected from the north eastern region of Turkey. The aerial parts were subjected to microdistillation for the isolation of volatiles that were subsequently analyzed by GC and GC/MS. The investigation resulted in the characterization of 30 components representing 92% of the total volatiles. Sesquiterpenes such as β-sesquiphellandrene (33.2%) and beta;-caryophyllene (20.2%) were assigned as major compounds.
