Chemical Constituents of Essential Oils of Wood and Wood Veneers of Tetraclinis Articulata (Vahl) Masters from Morocco

The essential oils obtained separately from both the untreated and treated wood (wood veneer) of Tetraclinis articulata (Vahl) Masters gathered from the area of Essaouira (Morocco) have been analyzed using GC and GC-MS. Remarkable qualitative and quantitative differences were found between the constituents in the samples studied. In the treated wood, the main components were carvacrol (41.2 % vs. 30.5% for untreated wood), O-methylthymodroquinone (10.8 % vs. 16.5 % for untreated wood) and cedrol (2.5 % vs. 12.1% for untreated wood). The present study shows that the wood veneers are source of essential oil and can be used in both medicinal and cosmetic purposes.
