%X Leaf and stem essential oils from Crotonpulegioides M¨¹ll.Arg. and C. rhamnifolius var. heliotropiifolius (Kunth) M¨¹ll.Arg were obtained by hydrodistillation and analyzed using gas chromatography and gas chromatography-mass spectrometry. The composition of the oils from the two Croton species was very different. The main components of the C. pulegioides oils were 1,8-cineole (15.86¡À 0.23% in leaf), p-cymene (14.40¡À 0.01% in leaf), camphor (13.28%¡À 0.12% in leaf) and ¦Á-humulene (12.98¡À 0.22% in leaf), ¦Á-calacorene (12.95¡À 0.45% in stem), cis-isolongifolane (8.94¡À0.54% in stem) and juniper camphor (6.44¡À0.45% in stem). The main components of the C. rhamnifolius var. heliotropiifolius oils were ¦Â-caryophyllene (20.82¡À0.48% in leaf), spathulenol (16.37¡À0.56% in leaf) and ¦Â-elemene (17.28¡À0.06% in stem) and guaiol (18.38¡À0.84% in stem). Phenylpropanoids common to Croton species were only found in C. rhamnifolius var. heliopropiifolius oils at percentages below 5%. This is the first report of the essential oil constituents of C. pulegioides and C. rhamnifolius var. heliotropiifolius from the Caatinga biome of the state of Pernambuco (Northeastern Brazil).
