AI Article Synopsis
- The study focused on the essential oils and supercritical CO2 extracts from wild Daucus carota L. subsp. carota collected from two different sites in Tunisia.
- Key components of the essential oil from Sejnane included eudesm-7(11)-en-4-ol and sabinene, while the Tunis samples were rich in elemicin and carotol.
- The antimicrobial effectiveness of these essential oils was tested against several bacterial and fungal strains, revealing that the Minimum Inhibitory Concentration (MIC) values were all greater than 2.5% (v/v).
Article 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%), a-selinene (7.4 - 8.6) and 11-alpha-(H)-himachal-4-en-1-beta-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).

Essential oils (EO) are a potential source of biologically active molecules. Knowing exactly the constituents of an EO is fundamental to verify its quality and to predict its biological potential and toxicity. Thus, the objective of this work is to determine the chemical constituents and the chemotype of the EO of Otanthus maritimus (L.

Bacteria have developed a cell-to-cell communication system called quorum sensing (QS), allowing them to regulate group behavior and synchronize the expression of virulence factors, responsible for increasing their infection capacity and resistance to antimicrobials. Although the control of microbial infections through the inhibition of microbial growth has traditionally been the basis of antimicrobial chemotherapy, the emergence of antimicrobial resistance has led to the search for new microbial control strategies, namely through the inhibition of QS. Among the agents studied to inhibit this bacterial communication are essential oils (EO), which are considered very effective QS inhibitors.
