“…Results showed that the combination of methanolic crude extract, chloroform and butanol fractions showed a pronounced antibacterial activity against Pseudomonas aeruginosa at all tested levels, while ethyl acetate and aqueous fractions showed synergistic effect against P. aeruginosa (Kirby Bauer method) (30) . The ISSN: 3009-7061 antibacterial activity of wild and planted Thuja orientalis essential oils exhibited that both tested essential oil possessed activity (31) . The effect of T. occidentalis extract against Pseudomonas aeruginosa was assessed in vitro and in vivo and results revealed that the test extract is able to reduce Pseudomonas aeruginosa infections (32) .…”

Thuja is one of Coniferous trees (family Cupressaceae). It comprises five species: Thuja occidentalis, Thuja koraiensis, Thuja plicata, Thuja standishii and Thuja sutchuenensis. This review aimed at gathering the botany, traditional uses, biological activities and phytoconstituents of Thuja species from 1984 until 2020, as they are considered generous sources of numerous phytoconstituents that may be used as scaffolds for new drugs with diverse pharmacological activities. Online bibliographies were searched using popular search engines, such as Google Scholar, PubMed, Springer, and Web of Science, in order to cover the botany, folk uses, biological activities and phytochemistry of Thuja plants. The review revealed that Thuja plants have diverse biological effects, and economic and folk uses. Moreover, the review showed the different phytoconstituents classes in Thuja plants. It can be concluded that Thuja plants are good candidates for intensive research to prove their biological activities by in vivo and clinical trials in order to get evidencebased drugs and discover new drugs for the treatment of several ailments.

“…L. kaempferi L. kaempferi is one of the main coniferous species in South Korea, so it is a major contributor to the national forest stock [17,18]. Because of this, most studies have been focused on the optimisation of plantations for efficient forest management [19][20][21], and there are limited studies on the extract and essential oils from L. kaempferi. The overall information on the essential oils extracted from the leaves and wood is summarised in Table 3.…”

The growing awareness of environmental issues has garnered increasing interest in the use of waste material in a wide variety of applications. From this viewpoint, developing essential oils from forest waste can bring new cost opportunities for the effective and sustainable management of unused forestry biomass. However, better knowledge of the production, chemical constituents, and application of essential oils is necessary. Among the species considered to be of interest from the point of view of their essential oils and forest biomass, Pinaceae and Cupressaceae were selected in this study as potential candidates for commercial essential oils based on previous studies. This current study focuses on investigating Pinaceae (Larix kaempferi, Pinus densiflora, and Pinus koraiensis) and Cupressaceae (Chamaecyparis obtusa and Chamaecyparis pisifera) essential oils extracted from various parts from the perspective of their bioactive compounds and potential applications. This is followed by an overview of the essential oils industry in South Korea, with particular attention being paid to utilising unused forest biomass. Therefore, this is a comprehensive review suggesting that Pinaceae and Cupressaceae essential oils extracted from various parts of forest waste could be utilised in various industries, adding value to the aspect of sustainable industry. Furthermore, our study contributes towards capturing the value of forest resources through the utilisation of native essential oils in South Korea.

“…Terpenes 1 to 3, and β-caryophyllene (4) are the major compounds found in essential oil from Chinese populations of T. orientalis (Bae et al, 2021). A comparison of the chemical composition of essential oils extracted from wild and planted T. orientalis leaves in Korea was carried out (Seo et al, 2019). The main compounds found in these essential oils were artemisiatriene (5, 17.7%), trans-isolimonene (6, 17.2%), terpinolene (7, 5.2%), and isopulegol (8, 4.8%).…”

“…The main constituents of essential oil from T. orientalis cultivated in Tokat, Turkey, were d-limonene (9, 36.7%), β-phellandrene (10, 36.7%), and β-myrcene (11, 15.3%). The quantitative and qualitative characteristics of secondary metabolites variation observed in these essential oils occur due to the existence of different chemotypes of a same species (Seo et al, 2019) and mainly by the influence of environmental conditions (Li et al, 2022). Gas chromatography coupled to mass spectrometry (GC-MS) analysis of the essential oil from leaves of T. orientalis cultivated in Egypt and Saudi Arabian showed a similar profile considering the major compounds (α-cedrol and β-caryophyllene).…”

Secondary metabolites and pharmacological potential of Thuja orientalis and T. occidentalis: A short review

2022

Species from Thuja genus (Cupressaceae) are found in Brazil, North America and Asia. In the traditional medicine, these plants are used in the treatment of cough, skin allergies, and asthma. In Brazil, Thuja species are also used in the ornamentation of urban areas. Different parts of these plants displayed insecticidal, antitumor, and antioxidant activities. The essential oil of the leaves from Thuja spp. are constituted by monoterpenes and sesquiterpenes. The main substances found in the extracts of these species are flavonoids, which display relevant biological activities. This brief review shows recent phytochemical studies involving T. orientalis and T. occidentalis, as well as 40 constituents isolated from these species. The existing pharmacological potential justifies the growing scientific interest in this genus.
