Abstract

The essential oils and supercritical CO2 extracts of wild Daucus carota L. subsp. carota from two different sites in Tunisia were investigated. The main components of the essential oil of the flowering and mature umbels with seeds from Sejnane were eudesm-7(11)-en-4-ol (8.2 –– 8.5%), carotol (3.5 - 5.2%), sabinene (12.0 -14.5%), ␣-selinene (7.4 –– 8.6) and 11-␣-(H)- himachal-4-en-1-␣-ol (12.7 –– 17.4%), whereas the oils from Tunis were predominantly composed of elemicin (31.5 –– 35.3%) and carotol (48.0 –– 55.7%). The antimicrobial activity of the essential oils were assayed by using the broth dilution method on Escherichia coli ATCC 35218 and Staphylococcus aureus ATCC 43300, and clinical strains of Candida albicans and C. tropicalis 1011 RM. The MIC values obtained were all > 2.5% (v/v).
