New sulfur components of pink guava fruit (Psidium guajava L.) / Robin A. Clery in The journal of essential oil research, Vol. 20 n°4 (Juillet/Août 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 n°4 (Juillet/Août 2008) . - pp. 315-317 Titre : New sulfur components of pink guava fruit (Psidium guajava L.) Type de document : texte imprimé Auteurs : Robin A. Clery, Auteur ; Christopher J. Hammond, Auteur Année de publication : 2008 Article en page(s) : pp. 315-317 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Psidium  guajava  Guava  Sulfur  constituents  3-mercaptohexanol  3-mercaptohexyl  acetate Résumé : A study of the key sulfur odor components of guava was undertaken by headspace and solvent extraction techniques. GC and GC/MS analysis identified five sulfur components; dimethyl disulfide, dimethyl trisulfide, benzothiazole, 3-mercaptohexanol and 3-mercaptohexyl acetate. Two of these compounds have not previously been reported as occurring in guava (3-mercapto- hexanol and 3-mercaptohexyl acetate). These compounds have a cassis-like odor and are thought to make an important contribution to the odor of guava.

Nitrogen compounds from haitian vetiver oil / Robin A. Clery in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 6 (Novembre-Décembre 2005) . - pp. 591-592 Titre : Nitrogen compounds from haitian vetiver oil Type de document : texte imprimé Auteurs : Robin A. Clery, Auteur ; Christopher J. Hammond, Auteur ; Anthony C. Wright, Auteur Année de publication : 2006 Article en page(s) : pp. 591-592 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Vetiveria  zizanioides  Vetiver  Essential  oil  composition  Pyrazines  Pyridines Résumé : Nitrogen containing compounds of vetiver oil, Vetiveria zizanioides (L.) Nash, have been investigated and 33 components identified by capillary GC and GC/MS. These include substituted pyridines, pyrazines and indolines; only four of which have previously been reported as occurring in vetiver oil. Two compounds, tentatively identified, are believed to be previously unreported as natural, namely, isomers of trimethylindoline and isocyanato-methylbenzene.

Nitrogen-containing compounds in black pepper oil (Piper nigrum L.) / Robin A. Clery in The journal of essential oil research, Vol. 18 N° 1 (Janvier-Fevrier 2006)

These species were found to be present at levels ranging from 150 ppb to 30 ppm. Odor assessment revealed that 2-ethyl-3,5-dimethylpyrazine (1.5 ppm) and 3-ethyl-2,5-dimethylpyrazine (490 ppb) contributed most significantly to the overall odor.
