Chemical composition and bactericidal evaluation of essential oil of Tetraclinis articulata burl wood from Morocco

Abstract

The composition and the antibacterial activity of the essential oil, isolated by hydrodistillation from the wood burl parts of Tetraclinis articulata from Morocco, were analyzed by GC and GC/MS. Fifteen compounds accounting for about 96% of the oil were positively identified. Cedrene (23%), thymol (22%), 3-tert-butyl-4-methoxyphenol (19%), cedrenol (9.6%), muurolene (5.4%), and sclarene (3%) were found to be the main constituents. The essential oil was tested for antimicrobial activity against four different genera of bacteria: Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae and Streptococcus D. and exhibited considerable inhibitory effects against all bacteria tested with MIC and MIB close to 1.25 ll/mL. The findings of the present study suggest that Tetraclinis articulata oil from hydro-distillation of sawdust from burl wood collected from artisans, has a potential to be used as bactericide.

“…In addition to these properties the leaves were also confirmed to be effective against Hypoglycemia and hypotension while the seeds were efficient against Hypoglycemia, 20,21 In comparison to Algeria, Tetraclinis articulata is used in the same ways and treatments in Morocco (anti-diabetic and anti-hypertensive). 17 According to Gonzalez-Tejero et al 47 this species is recommended against respiratory system diseases, moreover, according to Ziyyat et al 48 El Moussaouiti et al 49 Bourkhiss et al 50 Talbaoui et al 51 besides its anti-hypertensive and anti-diabetic virtues, this plant is characterized by a high antibacterial activity.…”

Chemical Variability of the Essential Oil Isolated from Aerial Parts of Tetraclinis Articulata from North-Western Algeria

“…It has been used as a diuretic, antipyretic, anti-rheumatic and oral hypoglycemic [3][4][5]. In parallel, various biological activities have been reported for extracts and essential oils (seeds, leaves, aerial parts) such as cytotoxic [6][7][8], vasorelaxant [9], antimicrobial [10][11][12][13][14][15][16][17][18][19][20], antioxidant and antiinflammatory activities [21,22].…”

Microstructural characterization and evaluation of certain important physical properties of thuja burl wood

“…Tetraclinis articulata is an evergreen conifer tree from the Cupressaceae family with the ability to develop burls generally found under the collar of tree. Being native to North-Western Africa and endemic to South-Western coast of the Mediterranean Sea, this species is mostly abundant in Morocco and North Africa and commonly known as Thuja, thuya, sandarac or Arar (Ibaez et al 1989, Hatimi 1994, Moussaouiti et al 2010, Sanchez-Gomez et al 2013. Other than Thuja, such wood burls are also found to occur on walnut, maple, redwood just to mention a few.…”

“…Other than Thuja, such wood burls are also found to occur on walnut, maple, redwood just to mention a few. Thuja burls are composed of mostly light and dark brown bands of high density woody tissues having random grain orientation and distinctive pleasant smell (Kaiser 1997, Moussaouiti et al 2010, Mouridi et al 2011a, Mouridi et al 2011b. Thuja burl wood is in great demand by the artisans due to its peculiar beauty, attractive grain patterns, texture, bands, etc.…”

“…The difference was attributed to the presence of different outgrowth concentrations between the lower and upper parts of the burl. Moussaouiti et al (2010) analysed the antibacterial activities of essential oil from Thuja burl wood and reported its high potential to control some microorganism growth including bacteria. Bouhtoury-Charrier et al (2009) also studied and reported biocidal activities of Thuja wood.…”
