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)

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%).

A comparative study of the composition of the leaf oils of three litsea species from borneo / Fasihuddin Bin Ahmad in The journal of essential oil research, Vol. 17 N° 3 (Mai-Juin 2005)  

Public ISBD [article]  inThe journal of essential oil research > Vol. 17 N° 3 (Mai-Juin 2005) . - pp. 323-326 Titre : A comparative study of the composition of the leaf oils of three litsea species from borneo Type de document : texte imprimé Auteurs : Fasihuddin Bin Ahmad, Auteur ; Ibrahim bin Jantan, Auteur ; Bukhori Abu Bakar, Auteur Année de publication : 2006 Article en page(s) : pp. 323-326 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Litsea resinosa gracilipes paludosa Lauraceae Essential oil composition Bulnesol β  -elemene Aromadendrene β  -caryophyllene Ledene Résumé : The chemical components of the leaf oils of Litsea resinosa Bl., L. gracilipes Hook. f. and L. paludosa Koesterm. were identified by co-chromatography with authentic samples on two capillary columns of different polarity, GC/MS and linear retention indices. The leaf oils were made up mainly of sesquiterpenoids. The oil of L. resinosa could be differentiated from the other samples due to its high contents of bulnesol (14.9%), β-caryophyllene (10.2%), β-elemene (10.2%) and other sesquiterpenoids. Ledene (9.0%) and aromadendrene (8.3%) were the major constituents in the leaf oil of L. gracilipes. Of the Litsea oils studied, this oil contained the highest concentrations of monoterpenoids with p-menth-1-en-9-ol (1.4%) as the major representative. The leaf oil of L. paludosa was found to possess some compositional similarities to the leaf oil of L. gracilipes but it could be distinguished from the latter by the significant presence of elemol (7.7%), γ-cadinene (2.9%), γ-eudesmol (2.8%), selin-11-en-4α-ol (2.3%), α-cadinene (2.1%), palustrol (1.7%) and selina-3,7(11)-diene (1.1%).

The oils were found to possess some compositional similarities but considerable variation in the levels of each component. The major components of the leaf oil were patchouli alcohol (27.7%) and benzyl benzoate (19.6%). Other compounds that were present in appreciable amounts in the oil were β-selinene (7.2%), geraniol (3.6%) and linalool (2.9%). The bark oil was characterized by the presence of higher concentrations of α-terpineol (9.7%) and linalool (7.5%) and relatively lower amounts of patchouli alcohol (10.5%) and benzyl benzoate (0.5%).
