Stapf collected in Mali and analyzed by GC and GC/MS. Fifty-four constituents (79.7% of the whole oil) were identifed. Prezizanoic acid (15.0%), preziza-7(15)-en-12-ol (9.5%), cedren-8-en-15-ol (6.2%), preziza-7(15)-en-3α-ol (6.0%) and zizanoic acid (5.9%) were the major components of Vetiveria nigritana oil.

A study on the composition of commercial vetiveria zizanioides oils from different geographical origins / Pascal Champagnat in The journal of essential oil research, Vol. 18 N° 4 (Juillet-Août 2006) 

Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° 4 (Juillet-Août 2006) . - pp. 416-422 Titre : A study on the composition of commercial vetiveria zizanioides oils from different geographical origins Type de document : texte imprimé Auteurs : Pascal Champagnat, Auteur ; Gilles Figuérédo, Auteur ; Jean-Claude Chalchat, Auteur Année de publication : 2006 Article en page(s) : pp. 416-422 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Vetiveria  zizanioides  Poaceae  Vetiver  oil  Essential  composition  Khusimol Résumé : This work reports the chemical composition of essential oils of Vetiveria zizanioïdes (L.) Nash from nine countries: Brazil, China, Haiti, India, Java, Madagascar, Mexico, Reunion and Salvador. Analyses were performed using GC/MS, and about 110 constituents were identified in oils, mainly sesquiterpenes. The characteristic constituents were β-vetispirene (1.6–4.5%), khusimol (3.4–13.7%), vetiselinenol (1.3- 7.8%) and α-vetivone (2.5- 6.3%). No meaningful differences were observed comparing the composition of nine geographical origins. Hierarchical clustering and principal component analysis (PCA) of the compositional data of the oil samples confirm the relative homogeneity of V. zizanioides by the content of major constituents (khusimol, β-vetivenene and β-vetispirene).
