“…formosana had the highest yield of essential oil (3.42%) followed by C. formosensis (3.14%), while C. japonica had the lowest yield (0.95%). These findings echo those of Chen et al [14] that C. obtusa var. formosana yielded more essential oil than C. formosensis (18.0 mL/kg vs 16.2 mL/kg, respectively).…”

Volatile organic compounds (VOCs) released from Chamaecyparis formosensis, Cryptomeria japonica, Cunninghamia lanceolata, Chamaecyparis obtusa var. formosana, and Taiwania cryptomerioides five major building and interior decoration timbers and their essential oil components were analyzed using GC-MS and TD/GC-MS/FID. Results showed that C. obtusa var. formosana had the highest yield of essential oil (3.42%), followed by C. formosensis (3.14%), while C. japonica had the lowest yield (0.95%). Moreover, oxygenated sesquiterpene was the highest relative content in all five essential oils and their main constituents were trans-myrtanol (18.04%), 1-epi-cubenol (15.99%), cedrol (62.26%), α-cadinol (26.42%), and α-cadinol (27.98%), respectively. In terms of emission quantity of top VOC, the results showed the decreasing order of C. formosensis (myrtenal, 74.21 mg/m 2) > T. cryptomerioides (thujopsene, 12.00 mg/m 2) > C. lanceolata (α-cedrene, 10.27 mg/ m 2) > C. obtusa var. formosana (α-pinene, 8.05 mg/m 2) > C. japonica (α-cedrene, 4.25 mg/m 2). C. formosensis had a greater amount of VOCs emitted and hence gave off more fragrance than C. obtusa var. formosana initially. However, after indoor exposure of 24 weeks, the VOC emission quantity of C. obtusa var. formosana exceeded that of C. formosensis. α-Cedrene and thujopsene were the top two major VOCs of both C. lanceolata and T. cryptomerioides. However, they both showed a trend of decrease in emission with prolonged exposure. All five plantation timbers showed good antifungal, antimicrobial, antibacterial, and antitermitic properties, making them ideal materials for interior decoration. Not only do they have strong bioactivities, they can also provide a fragrant and healthy living environment.

“…The concentrations of α-cubebene, β-caryophyllene, cis-muurola-3,5-diene, γ-cadinene, trans-muurola-4(14)5-diene, and δ-cadinene were higher in Room A. δ-cadinene and α-muurolol, components of the essential oil of Cananga odorata, regulate human autonomic nervous system (ANS) activity via the stimulation of parasympathetic nerve system (PSNS) activity [26]. The δ-cadinene and α-muurolol present in Meniki (Chamaecyparis formosensis) essential oil might be the factors in the increase of PSNS activity; it is possible that Meniki essential oil could improve ANS activity via an increase in HRV [27]. δ-cadinene was abundant in our room A and our results, thus, suggest that δ-cadinene influenced the physiological response and subjective evaluations.…”

Japanese cedar (Cryptomeria japonica) wood is widely used as a traditional construction material in Japan. The relationship between an individual’s perceived comfort level and a preference for Japanese cedar wood interiors is of interest. We compared volunteers’ physiological responses and subjective evaluations of wooden dwelling spaces with different wood materials: planed Japanese cedar lumber, or printed grain resin sheet overlay boards. Eighty-three subjects were asked to stay in each room for 30 min. We evaluated salivary stress markers, blood pressure, the profile of mood states-brief form (POMS), and a questionnaire that used the semantic differential method to evaluate the subjects’ feeling state for both rooms. The concentrations of the volatile organic compounds in both rooms were also quantified after the experiment. The results demonstrated that the subjects’ evaluation of each room was highly dependent on their preference; each room was evaluated more positively by subjects who preferred it. Although the subjects’ feelings were also influenced by their preference, the room with Japanese cedar did not elicit negative feelings, even from the subjects who disliked it. The subjects’ physiological responses were totally independent of their preferences. Their blood pressure decreased in the Japanese cedar room, and their salivary alpha-amylase activity was repressed in both rooms. These results indicated that the subjective evaluations were influenced in part by the subjects’ preferences, while their physiological responses were not affected. Regardless of which room the subjects preferred, the Japanese cedar room reduced the subjects’ blood pressure compared to the room with artificial materials.

“…Previous studies have been conducted on the habitability of rooms with wooden walls, and the psychophysiological favorite effects of interior wood material through visual and tactile pathways have been reported [ 4 , 5 ]. Volatile organic compounds (VOCs) from wood chips and essential oils produce relaxant effects on the autonomic nervous and electroencephalogram [ 6 – 9 ]. However, few studies have been performed on the psychophysiological responses to odors in a full-scale wooden environment.…”

BackgroundWood is a valuable material for interiors, and the psychophysiological relaxation effects of volatile organic compounds (VOCs) from wood chips and essential oils have been reported. However, few studies have identified the odors in full-scale wooden environment, and also, differences in gender have not been clarified. In this study, we aimed to confirm the effects of VOCs emitted from interior wood walls in both human male and female participants.MethodsWe used Japanese cedar timber and analyzed VOCs in the experimental rooms with and without Japanese cedar timber by gas chromatography-mass spectrometry (GC-MS). The physiological effects were measured using neuroendocrinological and immunological parameters in saliva. A questionnaire was used to evaluate the subjective responses to each odor in the experimental rooms.ResultsThe main compound emitted from Japanese cedar timber was δ-cadinene, and the total volume of VOCs in the wood condition (presence of VOCs emitted from Japanese cedar) was 282.4 (μg/m3). Significant differences between genders in salivary parameters were shown that there were decreases of α-amylase in wood condition and increases of cortisol in the control (absence of VOCs) condition in female participants compared to male participants. The results demonstrated that VOCs in the experimental room with Japanese cedar timber tend to suppress the activation of the sympathetic nervous activity and non-VOCs of Japanese cedar in the control room increase cortisol in female participants.ConclusionsThese results suggest that an indoor environment with wood interior materials has the potential to be useful for health management, especially women’s health.
