“…There are few studies on EO composition of T. broussonnetii in the literature. In previous studies, T. broussonnetii EOs extracted from Moroccan samples showed high levels of carvacrol, thymol, borneol, and p-cymene (Jaafari et al, 2007;Saad et al, 2010;El Bouzidi et al, 2013;El Ouariachi et al, 2014). This great variability in the chemical composition of T. broussonnetii EOs obtained from Moroccan samples can be most probably explained by the variability of the plant subspecies and the existence of different chemotypes.…”

“…Anethole and its isomers present in fennel oil are responsible for its antimicrobial effects (Gulfraz et al, 2008). Several studies have been published on the biological properties of Thymus capitatus as an antibacterial, antifungal and antioxidant agent (El Ouariachi et al, 2011).…”

“…Previous studies have demonstrated that Thymus species have strong insecticide, antioxidant, antibacterial, antifungal, antiviral, anti-inflammatory, and antispasmodic activity [11,16,17]. Different reports have shown that thymol and carvacrol are the main components of thymus EOs which are responsible for their high biological activities [18][19][20][21]. Among this genus, Thymus blecherianus and Riatarum locally called "zaatar" are the most important species from medicinal and aromatic properties and used worldwide for its antimicrobial activities.…”

Objective: The aim of the present study is to investigate chemical constituents of Thymus riatarum and Thymus blecherianus essential oils (EOs) as well as to evaluate, for the first time, their antioxidant effect and antibacterial activity against six bacterial strains responsible for nosocomial infections.Methods: The chemical composition of EOs was analyzed using gas chromatography (GC) and GC-mass spectrometry, the antibacterial capacity of the two thymus species was evaluated against six bacteria species: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus aureus, Acinetobacter baumannii, and Citrobacter sp. using disk diffusion method and microdilution assay. Finally, the antioxidant activity was measured by four different test systems of assay, namely free radical scavenging activities, ferric reducing/antioxidant power assays, total phenolic, and flavonoid contents.Results: A total of 15 compounds representing 99.6% of T. riatarum oil were identified with thymol (28.8%), borneol (20.0%), and α-phellandrene (13.0%) as the main constituents. Eleven components of T. blecherianus were identified representing 98.2% of the total oil composition; the most abundant constituents were as follows: Carvacrol (45.9%), bornyl acetate (20.1%), and borneol (15.7%). Strong antibacterial activity of the two EOs was identified against all bacterial strains tested. Concerning the antioxidant results, T. riatarum EO exhibited higher antioxidant activity than T. blecherianus in the three assays with an IC50 value equal to 5.75±0.06 mg/ml, which was probably due to its high content of polyphenols (28.95±0.13 mg GAE/g DW). Total flavonoid content was found equal for the two EOs.Conclusion: EO of T. riatarum and T. blecherianus from Morocco can be exploited as a natural antibacterial and antioxidant new potential sources.
