“…The steam distillation method was used to extract EOs from P. zhennan wood ( Shao et al., 2020 ). Fifty grams of wood powder from a tree of each age was soaked in distilled water until moistened and then put in a Soxhlet drawer for reflux extraction for 6 h. After stratification, the EOs were collected for liquid chromatography−mass spectrometry (LC−MS) and gas chromatography−mass spectrometry (GC−MS) analysis.…”

“…Essential oils (EOs) are extracted from aromatic plants and are lipid-soluble, volatile natural compounds with a rich aroma ( Shao et al., 2020 ). EOs are predominantly used in perfumes, cosmetics, and food flavoring due to the presence of these strong aromas ( Wani et al., 2021 ).…”

“…For woody perennials, the yield and composition of EOs also differed among parts (stem bark, branch bark, wood, and leaves) of the tree. For instance, there were 17 compounds in EOs extracted from the bark of Phoebe zhennan but 24 compounds in leaf oil ( Shao et al., 2020 ). A variety of EO compounds also exist in Cinnamomum camphora ; for example, the EO yields of leaves and branches are more than two times greater than those of wood, and the oxygenated monoterpene camphor is the major component in all tissues, except for safrole in the roots ( Poudel et al., 2021 ).…”

“…In our previous study, the main fragrance-related metabolites in P. zhennan heartwood were cadinene, p -cymene, and 1,3,5-triisopropylbenzene, which are sesquiterpenoids, monoterpenoids, and aromatic hydrocarbons, respectively ( Yang et al., 2023 ). Differences in the contents and major chemical compounds between the bark and leaf oils were observed in P. zhennan ( Shao et al., 2020 ). The determination of the main chemical components of EOs and VOCs affecting the quality of the wood and the establishment of quantitative methods can effectively help determine the quality of the wood in P. zhennan ; however, these main components and tree age effects are currently unknown.…”

Wood essential oil and wood products with special fragrances are high value-added forest products. Despite the availability of essential oil and volatile organic compounds (VOCs) from Phoebe zhennan wood, their variation and dependence on tree age have not been examined. After essential oil extraction and wood processing, the yields and compositions of essential oils and VOCs in wood from P. zhennan trees of different ages (10a, 30a, and 80a) were determined. The yield of essential oil from 30a wood was significantly greater than that from 10a and 80a wood. Liquid chromatography–mass spectrometry (LC−MS) and gas chromatography−mass spectrometry (GC−MS) revealed 672 and 41 volatile compounds, respectively, in the essential oil and wood, the majority of which exhibited large fluctuations in relative content and composition depending on tree age. Sesquiterpenoids, fatty acids and conjugates may greatly contribute to the main components of essential oil from wood. Almost all major sesquiterpenoid compounds, such as caryophyllene α-oxide, eudesmo, and cubebene, were identified in the essential oils from the 30a and 80a wood, and their relative contents were much greater than those in the 10a wood. The main components of the wood fragrance were sesquiterpenoids. The types and relative contents of sesquiterpenoids from wood increased with tree age. These results suggest that choosing wood from trees of a suitable age will significantly improve the efficiency of wood utilization.

“…In order to address the resources waste issues from the artificial Phoebe zhennan industry, previous research studied the chemical compositions, antioxidant and UV/Vis absorptivity of essential oils from bark and leaf of Phoebe zhennan trees [22]. Comparative analysis in chemical compositions and physicochemical characterization of essential oils between the modern and ancient Phoebe zhennan wood was also conducted in previous research to provide detailed information for potential utilization of the essential oils [20].…”

In this work, ethyl acetate (EA) and trichloromethane (TR) extracts were extracted from Phoebe zhennan wood residues and the extracts were then applied to the preparation of UV shielding films (UV-SF). The results revealed that substances including olefins, phenols and alcohols were found in both EA and TR extracts, accounting for about 45% of all the detected substances. The two extracts had similar thermal stability and both had strong UV shielding ability. When the relative percentage of the extract is 1 wt% in solution, the extract solution almost blocked 100% of the UV-B (280–315 nm), and UV-A (315–400 nm). Two kinds of UV-SF were successfully prepared by adding the two extracts into polylactic acid (PLA) matrix. The UV-SF with the addition of 24 wt% of the extractive blocked 100% of the UV-B (280–315 nm) and more than 80% of the UV-A (315–400 nm). Moreover, the UV shielding performance of the UV-SF was still stable even after strong UV irradiation. Though the addition of extracts could somewhat decrease the thermal stability of the film, its effect on the end-use of the film was ignorable. EA extracts had less effect on the tensile properties of the films than TR extracts as the content of the extract reached 18%. The results of this study could provide fundamental information on the potential utilization of the extracts from Phoebe zhennan wood residues on the preparation of biobased UV shielding materials.
