“…En effet, en se basant sur les travaux de Tzakou et al [22], les huiles essentielles de deux chémotypes de Thymus longicaulis riches en acétate de géranyl pour le premier et en acétate d'α-terpènyl pour le deuxième, possèdent une grande activité antimicrobienne. Cependant l'effet synergique entre tous ces constituants chimiques peut aussi être pris en compte dans cette activité [23,24].…”

RésuméLe rendement, la composition chimique et les propriétés antibactérienne et antifongique de l'huile essentielle extraite de la biomasse foliaire de Tetraclinis articulata (Vahl) du Khémisset (Maroc) ont été étudiés. La teneur moyenne en huile essentielle des feuilles de cette espèce est 0,22 % par rapport à la matière sèche. Trente quatre composés ont été identifiés par GC et GC/MS ; l'acétate de bornyle (30,74 %), l'α-pinène (23,54 %), le camphre (17,27 %) et le limonène (23,31 %) constituent les principaux composés de cette huile. Une forte activité inhibitrice vis-à-vis de six microorganismes utilisés a été enregistrée.Mots-clés.

“…Namazi, Allameh, Aminshahidi, Nohee, and Malekzadeh (2002) demonstrated that 0.9-1% ammonia inhibited fungal growth together with aflatoxin production. Thyme oils present high antimicrobial effect (Juliano, Mattana, & Usai, 2000;Karaman, Digrak, Ravid, & Ilcim, 2001;Tzakou, Verykokidou, Roussis, & Chinou, 1998) compared to the oils of other plants (Benjilali, Tantaoui-Elaraki, Ayadi, & Ihlal, 1984). These antimicrobial properties are related to the chemical composition of the oils, which varies within the different species of the genus Thymus and even within the samples of the same species (Granger & Passet, 1973).…”

“…It is a traditional remedy for cold, flu, cough, nephritis and abdominal pain [15][16][17][18]. To the best of our knowledge, there are several reports on the essential oil analysis of different taxa of T. longicaulis, and the results revealed their marked chemical variations depending on genetically determined properties, localities and environmental factors [19][20][21][22][23][24][25][26]. Three reports have been published concerning the antimicrobial activity of T. longicaulis recently.…”

Antimicrobial activity of Thymus longicaulis C. Presl essential oil against respiratory pathogens

Thymus longicaulis C. Presl is a small aromatic perennial herb used as a traditional remedy for cold, flu and cough. Composition of the essential oil of T. longicaulis from Croatia and its in vitro antimicrobial activity against the most common respiratory pathogens were evaluated. The yield of essential oil obtained by hydrodistillation from aerial plant parts was 1.2%. According to the GC-MS analysis, a total of forty one compounds (99%) were identified. Thymol (46.3%), γ-terpinene (16.2%), thymyl methyl ether (11.4%), and p-cymene (9.4%) were the main components. Antimicrobial activity of the essential oil against six clinically isolated bacterial and yeast strains was determined using standard disc agar diffusion method and microdilution broth assay. The essential oil exhibited antimicrobial activity towards all tested respiratory pathogens. The most sensitive strains were Haemophilus influenzae and Streptococcus pneumoniae(MIC=0.78 mg/mL), while Staphylococcus aureus was the most resistant (MIC>25.00 mg/mL). Our results indicate that T. longicaulis essential oil could be effective against clinically relevant respiratory pathogens which have the ability to develop resistance to antimicrobial drugs.
