Turmeric or curcuma (Curcuma longa L.) is a Zingiberaceae whose essential oil and coloring pigments obtained from the rhizome have been widely used in the food industry and medicine. This study aimed to extract and identify the chemical compounds found in C. longa essential oil from rhizomes collected in six different locations of Brazil. The oil extraction was carried out by hydrodistillation technique, using a Clevenger- type apparatus. The chemical constituents were identified by Gas Chromatography coupled to Mass Spectrometry (GC-MS). The principal component analysis (PCA) and the hierarchical cluster analysis (cluster)were done for the obtained data; and the composition of the studied accesses was verified. Three groups of chemotypes were obtained: group I was formed by the accesses of Campo Grande / Indígena-MS, Mara Rosa-GO, Campo Grande-MS and Perobal-PR, and had Ar-turmerone as its main compound; group II, formed by the access of Santa Tereza do Oeste-PR, presented α-costol and α-Phellandrene as the predominant compounds; and group III, the access of Holambra-SP, differed from the others regarding its essential oil chemical composition whose main agents were Curlone, Zingiberene, β-sesquiphellandrene, Humulene epoxide II, cis-α-trans-Bergamotol. The predominant chemical class in all accesses was hydrocarbon sesquiterpenes (Santa Tereza do Oeste-PR and Holambra-SP) and oxygenated sesquiterpenes (the others). This study evidenced the formation of three chemotypes
