“…The essential oil of C. japonica has been analyzed, but only mono- and sesquiterpenoids were reported [50]. Kaurenes and dehydroabietane with the lower terpenoids were reported for sugi leaf oil [51]. The minor resin acids have been characterized in bark and leaf extracts [27,28,29], and the chamaecydins were elucidated in leaf extracts from C. japonica [25,26].…”

The resins bled from stems and in seed cones and leaves of Cryptomeria japonica, Glyptostrobus pensilis, Taxodium distichum, and T. mucronatum were characterized to provide an overview of their major natural product compositions. The total solvent extract solutions were analyzed as the free and derivatized products by gas chromatography-mass spectrometry to identify the compounds, which comprised minor mono- and sesquiterpenoids, and dominant di- and triterpenoids, plus aliphatic lipids (e.g., n-nonacosan-10-ol). Ferruginol, 7α-p-cymenylferruginol, and chamaecydin were the major characteristic markers for the Taxodioideae conifer subfamily. The mass spectrometric data can aid polar compound elucidation in environmental, geological, archeological, forensic and pharmaceutical studies.

“…On the other hand, the three eudesmols are commonly found. For example, the aand P-eudesmols occur in various eucalyptus oils (11) as well as wood oil of Amyris bnlsami$ern (12) and the leaf oil of Cyptomeria jnponicn (13). In addition these sesquiterpene alcohols were also observed in Thujn korniensis, the a-and P-eudesmols being the main components (14).…”

Publication details, including instructions for authors and subscription information: ABSTRACT: Composition of the heartwood oil of Thuja occidentalis L. was investigated by a combination of capillary GC (retention indices) and GUMS. The oil was obtained by steam &stillation ofvarious lots ofwaste residues from cedar shingle industries. Twelve out of 20 observed compounds were identified. Monooxygenated sesquiterpene compounds are the most important components (80% of the total). Occidentalol is the main component: its relative concentration varies between 20% and 50%, dependng on the isolation parameters. This concentration decreased as the isolation proceeded, typically from 40-50% to 10-20% between 1 and 5 hours of &stillation. Three occidol isomers, occidenol, and a-, p-, and y-eudesmols were also observed in relative concentrations of 4% to 12%. The monoterpene family is represented by terpinen-4-01, and carvacrol. a-Thujaplicin, a tropolone derivative, is also among the products. The relative concentration of thujaplicin decreased from 5% to 0% between 1 and 5 hours of distillation.

Acacia nilotica (synonym: Vachellia nilotica (L.) P.J.H.Hurter and Mabb.) is considered an important plant of the family Fabaceae that is used in traditional medicine in many countries all over the world. In this work, the antiviral potentialities of the chemically characterized essential oils (EOs) obtained from the bark and fruits of A. nilotica were assessed in vitro against HAV, HSV1, and HSV2. Additionally, the in silico evaluation of the main compounds in both EOs was carried out against the two proteins, 3C protease of HAV and thymidine kinase (TK) of HSV. The chemical profiling of the bark EOs revealed the identification of 32 compounds with an abundance of di- (54.60%) and sesquiterpenes (39.81%). Stachene (48.34%), caryophyllene oxide (19.11%), and spathulenol (4.74%) represented the main identified constituents of bark EO. However, 26 components from fruit EO were assigned, with the majority of mono- (63.32%) and sesquiterpenes (34.91%), where trans-caryophyllene (36.95%), Z-anethole (22.87%), and γ-terpinene (7.35%) represented the majors. The maximum non-toxic concentration (MNTC) of the bark and fruits EOs was found at 500 and 1000 µg/mL, respectively. Using the MTT assay, the bark EO exhibited moderate antiviral activity with effects of 47.26% and 35.98% and a selectivity index (SI) of 2.3 and 1.6 against HAV and HSV1, respectively. However, weak activity was observed via the fruits EO with respective SI values of 3.8, 5.7, and 1.6 against HAV, HSV1, and HSV2. The in silico results exhibited that caryophyllene oxide and spathulenol (the main bark EO constituents) showed the best affinities (ΔG = −5.62, −5.33, −6.90, and −6.76 kcal/mol) for 3C protease and TK, respectively. While caryophyllene (the major fruit EO component) revealed promising binding capabilities against both proteins (ΔG = −5.31, −6.58 kcal/mol, respectively). The molecular dynamics simulation results revealed that caryophyllene oxide has the most positive van der Waals energy interaction with 3C protease and TK with significant binding free energies. Although these findings supported the antiviral potentialities of the EOs, especially bark EO, the in vivo assessment should be tested in the intraoral examination for these EOs and/or their main constituents.
