“…The identities of compounds identified in the oil samples could be seen in tive compounds of previous studies on C. tonkinensis [3,4]. The α-pinene content of this oil competes favourably with previous studies while the contents of other monoterpenes above are significantly lower.…”

“…Little is known about the chemical constituents and biological potential of this plant. Leaves and stems of C. tonkinensis produce monoterpene-rich oils whose composition is α-pinene (23.1%), sabinene (21.0%) and terpinen-4-ol (14.4%) in the leaf while, α-pinene (42.5%), myrcene (10.2%) and cedrol (9.0%) were identified in the stem [4]. Another investigation identified sabinene (29.34%), α-pinene (25.4%), 4-terpineol (13.91%) and -terpinene (5.5%) as major compounds of its leaf oil [3].…”

In the present investigation, we studied new essential oil contents and compositions of three individual plants from Cupressaceae family cultivated in Vietnam. The air-dried plants were hydrodistilled and the oils analysed by Gas chromatography (GC) and Gas chromatography couples with Mass spectrometry (GC-MS). The components were identified by comparison of their retention indices on HP-5 MS capillary column with literature reference and MS pattern with authentic library's collection. -Pinene (36.0%), α-cedrol (18.3%) and thujopsene (5.7%) were the main constituents of Cupressus tonkiensis Silba. Monoterpenes were the quantitative significant compounds of Sabina chinensis (L.) Antoine. These are bornyl acetate (19.5%), sabinene (17.3%) and -pinene (15.8%). Moreover, the main compounds of Thuja orientalis L., were identified as -pinene (34.1%), α-cedrol (16.5%), β-caryophyllene (5.4%) and β-selinene (5.2%). The chemotaxonomy implication of these results was also discussed.

“…However, concerning their thujone-producing potential, these taxa are rather different. In the genus Cupressus, thujone has not been identified in any of the following species which were subjects of phytochemical investigations: C. arizonica (Ali et al 2013), C. atlantica, C. chengiana, C. doclouxiana, C. guadalupensis, C. macnabiana, C. sachmeriana (Pierre-Leandri et al 2003), C. tonkinensis (Thai et al 2013), C. torulosa (Padalia et al 2013), C. funebris (Carroll et al 2011;Pierre-Leandri et al 2003), and C. sempervirens (Mazari et al 2010;Ulukanli et al 2014).…”

Thujone is a volatile monoterpene ketone of plant origin which is produced by several plants that are frequently used for flavoring foods and beverages. The use of thujone and thujone-containing plant parts for human consumption is currently regulated by the European Parliament and Council and the European Medicines Agency. The best known neurotoxic effects are connected to the GABA-gated chloride channel, where a-thujone is a modulator roughly two to three times as potent as the b isomer. Based primarily on in vitro experiments, genotoxicity and carcinogenic properties of thujones have also been detected in parallel with antimutagenic and immune-modulatory effects. Some of the controversial effects seem to be strongly dose-dependent. Data on antidiabetic and antimicrobial activities of thujones may show new ways to use them. This review also describes the main steps of the biosynthetic route of thujones and their occurrence in the plant kingdom. The accumulation of these compounds seems to be more abundant in some plant families (e.g. Asteraceae or Cupressaceae) than in others. Four species (Artemisia absinthium, Salvia

“…Therefore, we believed that, in combination with phenotypic and genetic parameters, the chemical composition of EO isolated from various parts of the tree could bring useful information about the species of the pine growing wild in Son La Province, Vietnam. In continuation of our work on the characterization of Vietnamese conifers (Cupressus tonkinensis, Fokienia hodginsii, Xanthocyparis vietnamensis) through the composition of their EOs [10][11][12] the aim of the present paper was to get more insight on the composition of EOs isolated from various organs of the recently discovered Pinus cernua (P. armandi subsp. xuannhaensis): needle oil, cone oil, and branch oil.…”

Conifers are well represented in Vietnam where a new pine species has been recently discovered in Son La province: Pinus cernua, synonym P. armandii ssp. xuannhaensis. The compositions of needle, cone, and branch oils have been investigated by gas chromatography (retention index), gas chromatography-mass spectrometry, and 13 C nuclear magnetic resonance. Myrcene (47.0%) was the main component of needle oil, followed by β-pinene (28.4%) and α-pinene (12.5%). Branch oil also contained myrcene (32.8%), α-pinene (17.9%), β-pinene (9.8%), and a high content of limonene (20.0%). Finally, cone oil displayed α-pinene (44.1%) beside myrcene (11.5%), β-pinene (8.1%), and limonene (5.8%).
