Antioxidant and Antibacterial Activities of the Essential Oil of Moroccan Tetraclinis articulata (Vahl) Masters

Abstract

The purpose of this study is to evaluate and compare the antioxidant and antibacterial activities of essential oil isolated from Tetraclinis articulata (Vahl) leaves, Masters originating in Morocco (Benslimane Region, Atlantic-influenced plain). The analysis of the major compounds of essential oil was performed by gas chromatography and mass spectrometry, and this oil is dominated by bornyl acetate (35.05%), camphor (11.17%), and α-pinene (10.84%). The antioxidant properties were evaluated by the test of the radical trap 2,2-diphényl-1-picrylhydrazyl (DPPH), and the antimicrobial activity of T. articulata essential oil was tested against clinical isolates of Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli which have been inhibited from the 25 μg/mL.

Phytochemical Profile and In Vitro Antioxidant, Antimicrobial, Vital Physiological Enzymes Inhibitory and Cytotoxic Effects of Artemisia jordanica Leaves Essential Oil from Palestine

“…The results of the present investigation revealed that (AJ) EO has potent antibacterial and antifungal potentials against certain strains of microbial species. Actually, bornyl acetate, the study’s main molecule, has long been recognized as a potent antimicrobial agent, according to numerous published studies [ 36 , 54 , 55 ].…”

Antimicrobial activity of Tetraclinis articulata aerial parts essential oil from Tlemcen, Northwestern of Algeria

“…It has been used as a diuretic, antipyretic, anti-rheumatic and oral hypoglycemic (Bellakhdar et al, 1982;Ziyyat et al, 1997). In parallel, various biological activities have been reported for extracts and essential oils (seeds, leaves, aerial parts) such as cytotoxic (Buhagiar et al, 1999;Aouinty et al, 2006), vasorelaxant (Zidane et al, 2014), antimicrobial (Bourkhiss et al, 2007a;Abi-Ayad et al, 2011;Chikhoune et al, 2013;Djouahri et al, 2016;Ben Ghnaya et al, 2016;Ibrahim et al, 2017;Rabib et al, 2019;2020), antioxidant and anti-inflammatory activities (Bourkhiss et al, 2010;Djouahri et al, 2013). The antimicrobial activity of T. articulata essential oil has been the subject of a many studies.…”

“…Another oil sample isolated from the leaves of T. articulata exhibited very good sensitivity against six bacteria: Salmonella enterica, Klebsiella pneumoniae, Listeria monocytogenes, Pseudomonas aeruginosa, S. aureus, E. coli, Fusarium culmorum, Aspergillus flavus and Candida albicans, with inhibition zones diameters in the range of 11.5 -25.3 mm and MIC values ranging between 0.25 and 50 µg/mL (Djouahri et al, 2016). Rabib et al (2019;2020) also reported very low MICs values (1.56 -50 µg/ml) for leaves essential oil of T. Articulata, against Pseudomonas aeruginosa, S. aureus and E. coli. Ibrahim et al in 2017 reported on the antibacterial activity of T. articulata leaf oil.…”

Chemical Composition and Cytotoxic Activity of the Fractionated Trunk Bark Essential Oil from Tetraclinis articulata (Vahl) Mast. Growing in Tunisia

“…Medicinal and aromatic plants (MAPs), in their entirety or their separated parts, are used as they are or can be further processed by extraction of essential oils and are considered an important resource in various fields, such as pharmaceutical, flavor and fragrance, perfumery, and cosmetic industries [ 1 ]. Essential oils from medicinal and aromatic plants are a very interesting source of secondary metabolites because of their many different biological properties, such as cytotoxic [ 2 ], anti-inflammatory [ 3 ], antioxidant [ 4 ], insecticidal [ 5 ], antifungal [ 6 ] and antimicrobial [ 7 , 8 , 9 ], many of which are of increasing interest in the field of human and animal health. In recent years, the development of antibiotic resistance represents the major issue in medical microbiology and the search for new weapons against antibiotic resistances has led to the search of new sources of potential antimicrobials.…”
