Essential oils from the stem barks of C. conduplicatus were obtained by hydrodistillation after 2, 3 and 4 h of extraction with a very high percentage (95.93, 96.69 and 98.45%, respectively) of identified total components present in crude essential oils. Analyses were made by gas chromatography/mass spectrometry (GC/MS). The most abundant constituents were a-pinene, pinene, camphor and (E)-caryophyllene. The occurrence of a-pinene and pinene has been reported in essential oils of several other species of Croton, indicating that this species is typically of the Euphorbiaceae family.  aCaatinga  aOleo essencial  aPlanta medicinal  aBioma  aComponentes voláteis  aCroton conduplicatus  aEssential oil  aPlanta nativa  aQuebra faca1 aSOUZA, A.
