It is an endangerous biome, considered a biodiverisity hotspot (Myers et al., 2000). Calea teucriifolia (syn Meyeria teucrifolia) is a shrub native from the Cerrado. Samples from a population (n>5) were collected from a rupestrian field in the Serra dos Pirineus National Park, in Goiás State, Brazil. A voucher was deposited at the Embrapa Genetic Resources herbarium (CEN 84468) and the essential oil obtained from the leaves by hydrodistillation for 2 h, using a Clevenger-type apparatus. It was analyzed by GC-MS and GC-FID using an Agilent 6890 GC coupled to an Agilent 5973N mass selective detector, fitted with a HP5-MS capillary column. Identification was performed by both mass spectra and linear retention indices. Oil yield was 0.3 %. The major compounds found were p-cymene (15.2 %), myrcene (13.5 %), caryophyllene oxide (9.7 %) and α-phellandrene (9.5 %). The oil composition is quite different from other Calea, like C. clematidea, rich in clematerol, a terpenic epoxide (Flach et al., 2002). A previous phytochemical study on the hexane extract of C. teucriifolia identified two nerolidol derivatives, together with some sesquiterpenes and a furanoheliangolide (Bohlmann et al., 1981). To the best of our knowledge, this is the first analysis on the essential oil from Calea teucriifolia.  Keywords: Essential oil composition, Calea teucriifolia, Asteraceae, Cerrado.
