Abstract
Plant oils have been used for wide variety purposes for many years in Turkey.
These essential oils have usage in many areas such as perfumery, cosmetic, food flavoring and folkloric medicine.
In the study, 19 commercial essential oils were studied by means of antibacterial and antioxidant capacity.
Antibacterial test was performed against S. aureus, S. epidermidis, K. pneumoniae and E. coli using standard disc diffusion method.
Penicillin, gentamicin and vancomycin discs were also included.
Inhibition zones (mm) were recorded to indicate antibacterial property.
Penicillin (44 mm) and vancomycin (14 mm) could inhibit only S. aureus. Except essential oils of Juniperus nana (Ardıç), Ocimum basilicum (Fesleğen), Urtica dioica (Isırgan), Foeniculum vulgare (Rezene) remaining essential oils indicated antimicrobial activity against some of the test microorganims.
The most active essential oil was found as Thymus serpyllum (Kekik). It indicated highest inhibition zones for other microorganisms among others.
Antioxidant capacities were measured using photochemiluminescence (PCL) method.
The highest antioxidant activity was measured for Dianthus caryophyllus (Karanfil) as 547.781 103 µg trolox/mL of oil.
It was followed by Thymus serpyllum (Kekik), Lilium candidum (Zambak) and Matricaria chamomilla (Papatya). Especially, Thymus serpyllum and Dianthus caryophyllus have significant antimicrobial and antioxidant capacity therefore it could be suggested for further investigations and applications.
