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).
