Acantholippia deserticola (Phil.ex F. Phil.) Moldenke is a Verbenaceae that has long been used in traditional medicine in Tarapacá (Chile) as an analgesic, anti-inflammatory and aphrodisiac agent. Since-and -thujone were identified as the main constituents (88.4%) of the essential oil from this plant, we investigated its biological properties. The results show that the essential oil from Acantholippia deserticola decreased locomotive and rearing activity compared to control group rats, including those treated with diazepam, but the essential oil had no effects on head movements or grooming. The essential oil also had significant anxiolytic and antidepressant effects. This essential oil, therefore, has sedative, anxiolytic and antidepressant actions on the rat central nervous system. © 2013 Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas.
