The chemical composition of essential oil samples of the aerial parts of  Lantana canescens, Lantana tilcarensis, Lantana trifolia, Aloysia citriodora,  Aloysia gratissima, Aloysia castellanosii and Aloysia catamarcensis from northwest of Argentina, phytogeographic areas of Yungas, Puna, Parque Chaqueño and Monte, have been characterized by GC and GC/MS. The main essential oil component group present in aerial parts of Lantana were sesquiterpenes hydrocarbons (>24.8%). On the other hand, the main compound groups and percentages found in oils of Aloysia were oxygen-containing monoterpenes (>19.6%).  The comparison with previous studies performed by other authors points to a significant variation in the chemical composition of essential oil depending from the origin of the plants.
