Chemical constituents of the bark oil of goniothalamus macrophyllus hook. f. from Malaysia / Ibrahim bin Jantan in The journal of essential oil research, Vol. 17 N° 2 (Mars-Avril 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 2 (Mars-Avril 2005) . - pp. 181-183 Titre : Chemical constituents of the bark oil of goniothalamus macrophyllus hook. f. from Malaysia Type de document : texte imprimé Auteurs : Ibrahim bin Jantan, Auteur ; Fasihuddin Bin Ahmad, Auteur ; Laily bin Din, Auteur Année de publication : 2006 Article en page(s) : pp. 181-183 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Goniothalamus  macrophyllus  Annonaceae  Essential  oil  composition  Terpinen-4-ol  1,8-cineole  Geranyl  acetate  (Z)-β-ocimene  α-terpineol Résumé : The bark oils of Goniothalamus macrophyllus Hook. f., obtained from two different sites, were investigated by capillary GC and GC/MS. The oils were found to possess little differences in the chemical composition but considerable variation in the levels of the individual components. The oils were rich in monoterpenoids (91.8–94.0%), with terpinen-4-ol at 38.8% and 42.7%, respectively, as the dominant component. The major differences between the oils were the presence of appreciable amounts of 1,8-cineole (18.1%), geranyl acetate (11.1%) and geraniol (9.7%) in one sample and relatively low amounts of these compounds in the other sample. However, the latter sample contained signifi cantly higher concentrations of (Z)-β-ocimene (25.4%) and α-terpineol (10.0%).
