Abstract The chemical compositions of the essential oils from the leaves collected of Lippia gracilis Schauer at two localities in the bioma caatinga of Pernambuco were analyzed by GC and GC/MS, where a total of thirty-six compounds were identified in the oils from all the samples. The chemical profiles of samples from the same locations were the same having only relative changes in composition. But the chemical compositions of oils collected in the vicinity of Buique in the Agreste of Pernambuco were quite different from the ones collected in Ouricuri in the Sertão. The main components identified in samples from Buique were carvacrol (36.4–45.0%) and p-cymene (18.1–26.2%), while thymol (37.4%), γ-terpinene (14.9–20.5%) and 4-methoxy-acetophenone (10.1–12.4%) were the major components found in the specimen collected in Buique.
