• The volatile oils from four species of genus Lippia of the Verbenaceae family, Lippia turbinata, L. polystachya, L. junelliana and L. integrifolia have been examined by means of GC/MS and IR in combination with retention indices. The main constituents of the essential oil of L. turbinata were found to be alpha-thujone (28.29%), carvone (7.40%), beta-caryophyllene (5.39%), germacrene-D (5.16%), bicyclogermacrene (4.53%), spathulenol (6.06%) and caryophyllene oxide (7.03%). The volatile oil of L. polystachya was found to contain alpha-thujone (68.94%) and carvone (10.34%) as major components. The oil from L. junelliana was characterized by the presence of large amounts of myrcenone (15.48%), myrcene (7.92%), limonene (9%), camphor (10.55%), (E)-tagetenone (6.30%), trans-dihydrocarvone (5.85%) and cis-dihydrocarvon (16.65%). The main components of the volatile oil of L. integrifolia were shown to be camphor (16.20%), africanene isomers 5.04%), lippifoli-1(6)-en-5-one (16.70%) and an unidentified component (14.89%)
