“…Mohareb et al [ 47 ] studied the antifungal activity of essential oils from eighteen different Egyptian plants against wood-decaying fungi Hexagonia apiaria and Ganoderma lucidum . The best resistance was obtained for Scots pine sapwood treated with Artemisia monosperma , Citrus limon , Cupressus sempervirens , Pelargonium graveolens , Schinus molle and Thuja occidentalis oils.…”

Wood is a renewable, versatile material with multiple applications and the largest terrestrial pool of sequestered carbon. However, it is susceptible to degradation, mainly caused by wood-decaying fungi. Since several traditional wood preservatives have been banned owing to their detrimental effects on humans and the environment, extending the lifespan of wood products using new generation natural preservatives is an imperative from the perspectives of human health and environmental protection. Several natural compounds of plant and animal origin have been tested for their fungicidal properties, including essential oils, tannins, wood extractives, alkaloids, propolis or chitosan; and their enormous potential in wood protection has been shown. Although they are not free of limitations, the potential methods to overcome their drawbacks and enhance their bioactivity already exist, such as co-impregnation with different polymers, cross-linkers, metal chelators or antioxidants. The presence of the discrepancies between laboratory tests and the field performance, as well as legislation-related problems resulting from the lack of standards defining the quality and performance of natural protective formulations, however, create an urgent need for further thorough research and arrangements. The collaboration with other industries interested in the utilisation of natural active compounds will reduce the associated costs, thus, will facilitate the successful implementation of alternative antifungal agents.

“…Several papers described T. occidentalis essential oil, its chemical composition [8][9][10][11][12][13] and additional biological activities: antimicrobial [14][15][16][17] and insecticidal [18][19][20][21][22]. The following factors influence the yield and chemical composition of the oil: origin of the plants [8-12, 14, 18, 19], cultivar variety [13,15], harvest season [9,13], technique of oil isolation [8,9] and time of hydrodistillation [10].…”

S u m m a r yIntroduction: Thuja occidentalis 'Brabant' and T. occidentalis 'Smaragd' are widely planted as decoration in parks and as hedges in domestic gardens in Poland. Objective: The aim of the study was to determine the yield and the composition of essential oils from different parts of these cultivars. Methods: The essential oils were obtained by hydrodistillation, and then analyzed by GC/MS. Results: Over seventy compounds were identified. The oils from leaves, twigs with leaves and twigs without leaves of 'Brabant' variety contained mainly α-thujone (61.0-64.4%), β-thujone (10.4-10.7%) and fenchone (7.7-8.0%), whereas in the cone oil there were α-thujone (42.1%), sabinene (11.2%) and β-thujone (10.2%). The main constituents of the oil from leaves and twigs with leaves of 'Smaragd' variety were α-thujone (49.2-49.3%), beyerene (12.8-13.2%) and sabinene (8.9-9.3%). Conclusions: The yield and chemical composition of the essential oil of T. occidentalis depend on the variety and plant organ. The oil of 'Brabant' variety contained more thujones and less diterpenes in comparison with the oil of 'Smaragd' variety.

Lavandula pubescens Decne (LP) is one of the three Lavandula species growing wildly in the Dead Sea Valley, Palestine. The products derived from the plant, including the essential oil (EO), have been used in Traditional Arabic Palestinian Herbal Medicine (TAPHM) for centuries as therapeutic agents. The EO is traditionally believed to have sedative, anti-inflammatory, antiseptic, antidepressive, antiamnesia, and antiobesity properties. This study was therefore aimed to assess the in vitro bioactivities associated with the LP EO. The EO was separated by hydrodistillation from the aerial parts of LP plants and analyzed for its antioxidant, antimicrobial, anticholinesterase, and antilipase activities. GC-MS was used for phytochemical analysis. The chemical analysis of the EO composition revealed 25 constituents, of which carvacrol (65.27%) was the most abundant. EO exhibited strong antioxidant (IC50 0.16–0.18 μL/mL), antiacetylcholinesterase (IC50 0.9 μL/mL), antibutyrylcholinesterase (IC50 6.82 μL/mL), and antilipase (IC50 1.08 μL/mL) effects. The EO also demonstrated high antibacterial activity with the highest susceptibility observed for Staphylococcus aureus with 95.7% inhibition. The EO was shown to exhibit strong inhibitory activity against Candida albicans (MIC 0.47 μL/mL). The EO was also shown to possess strong antidermatophyte activity against Microsporum canis, Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum (EC50 0.05–0.06 μL/mL). The high antioxidant, enzyme inhibitory, and antimicrobial potentials of the EO can, therefore, be correlated with its high content of monoterpenes, especially carvacrol, as shown by its comparable bioactivities indicators results. This study provided new insights into the composition and bioactivities of LP EO. Our finding revealed evidence that LP EO makes a valuable natural source of bioactive molecules showing substantial potential as antioxidant, neuroprotective, antihyperlipidemic, and antimicrobial agents. This study demonstrates, for the first time, that LP EO might be useful for further investigation aiming at integrative CAM and clinical applications in the management of dermatophytosis, Alzheimer’s disease, and obesity.
