Purity, antimicrobial activities and olfactoric evaluations of geraniol/nerol and various of their derivatives / Leopold Jirovetz in The journal of essential oil research, Vol. 19 N°3 (Mai/Juin 2007)  

Public ISBD [article]  inThe journal of essential oil research > Vol. 19 N°3 (Mai/Juin 2007) . - pp. 288-291 Titre : Purity, antimicrobial activities and olfactoric evaluations of geraniol/nerol and various of their derivatives Type de document : texte imprimé Auteurs : Leopold Jirovetz, Auteur ; Gerhard Buchbauer, Auteur ; Erich Schmidt, Auteur Année de publication : 2007 Article en page(s) : pp. 288-291 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Geraniol Nerol Geranial Geranyl acetone Geranic acid esters geraniol linalool Résumé : Commercially available geraniol and nerol, as well as some derivatives, were analyzed for their purity using GC and GC/MS. The olfactoric quality of the samples was evaluated by professional perfumers. Antimicrobial testings using an agar dilution and an agar diffusion method were done to obtain information about their activities against some Gram-(+) and Gram-(−) bacteria, as well as the yeast Candida albicans. The effects were compared with those of the phenolic compound eugenol and some synthetic antibiotics. Most of the investigated compounds were found to have a characteristic, pleasant odor and a high activity against all strains of microorganisms used.

Purity, antimicrobial activities and olfactory evaluations of 2-phenylethanol and some derivatives / Leopold Jirovetz in The journal of essential oil research, Vol. 20 N°1 (Janvier/Fevrier 2008)

The olfactory quality of the samples was evaluated by professional perfumers. Antimicrobial tests using an agar dilution and an agar diffusion method were done to obtain information about their activities against some Gram-positive and Gram-negative bacteria as well as the yeast Candida albicans. The effects were compared with those of the phenolic compound eugenol and some synthetic antibiotics. Most of the investigated compounds were found to show a characteristic, pleasant odor, mostly with a sweet-floral top-note, but do not possess a high activity against many strains of microorganisms used.
