项目摘要
(1)Sensory TestBased on perceptional change of fragrance of essential oils, a simple screening test for efficacy of aroma was developed in relation to type of work, that is, mental work, physical work and hearing environmental (natural) sounds. In evaluating change in perception of a given aroma, a sensory test was employed, in which perception of fragrance was assessed by 13 contrasting pairs of adjectives. Scores were recorded after inhaling a fragrance before and after each type of work, and the statistical significance of the change of score for 13 impression descriptors was examined by Student's t-test for each type of work.Among 16 essential oils examined in this study including orange, geranium, cypress, bergamot, juniper and others, it was confirmed that inhalation of essential oil caused a different subjective perception of fragrance depending on type of work. For example, inhalation of cypress after physical work produced a much more favorable impression than that before work … More in contrast to the case for orange, which produced an unfavorable impression after physical work when compared to that before work. As for mental work, too, inhalation of juniper seemed to create a favorable impression after work, while the feature was completely opposite to that for geranium and orange, both producing an unfavorable impression. We thus concluded that the sensory test might serve not only as a screening test for efficacy of aroma but also as a categorized table for aroma samples which can act as reference to each other.(2) Study of Physiological EffectsAs for the physiological effects on humans of inhalation of essential oils, optically active linalools were examined in terms of sensory tests and portable forehead surface electroencephalographic (IBVA-EEG) measurements from the view of their relation between odor distinctiveness and reactions by chiral isomers. R-(―)- linalools with specific rotation of 〔α〕ィイD2DィエD2=-15.1° was isolated by repeated flash column chromatography from lavender oil, while (S)-(+)-linalools with 〔α〕ィイD2DィエD2=17.4 and (RS)-(±)-linalools with 〔α〕ィイD2DィエD2=0°and content of R-form 50.9% and (S)-form 49.1% were obtained from coriander oil and commercial linalool, respectively, by using the same method. With use of inhalator, each was administered to subjects both before and after 10 minutes of work. It was found that enantiometric stereospecificity of linalool evoked different odor perception and responses not only with chiral-dependence but also with task-dependence. Less
(1)感官测试根据精油香味的感知变化,根据工作类型,即脑力劳动、体力劳动和听觉环境(自然)声音,开发了一种简单的香气功效筛选试验。在评估变化的感知给定的香气,一个感官测试被采用,其中对香味的感知是由13对对比形容词评估。在每一种工作前和工作后分别吸入香水,记录得分,并对每一种工作的13个印象描述符的得分变化进行学生t检验。在本研究中检测的16种精油中,包括橙、天竺葵、柏树、佛手柑、杜松等,证实了吸入精油会导致不同工作类型对香味的主观感知不同。例如,在体力劳动后吸入柏树比工作前产生了更有利的印象……与此相反的是,与工作前相比,橙色在体力劳动后产生了不利的印象。对于脑力工作,吸入杜松似乎下班后给人一种良好的印象,而吸入天竺葵和橙则完全相反,都给人一种不好的印象。因此,感官测试不仅可以作为香气功效的筛选测试,而且可以作为香气样品的分类表,可以相互参考。(2)生理效应的研究针对人体吸入精油后的生理效应,采用感官试验和便携式额表脑电图(IBVA-EEG)测量方法,从气味特异性与手性异构体反应的关系出发,研究了旋光性芳樟醇对人体的生理效应。R -(-) -芳樟醇与特定的旋转(α)ィイD2DィエD2 = -15.1°被重复孤立闪光柱层析法从薰衣草油,而(S) -(+)和(α)-linaloolsィイD2DィエD2 = 17.4 (RS)——(±)-linalools(α)ィイD2DィエD2 = 0°和R形式内容50.9%和(S)—构成49.1%是来自芫荽油和商业芳樟醇,分别通过使用相同的方法。使用吸入器,分别在工作前和工作后10分钟给予受试者。结果表明,芳樟醇的对映立体特异性不仅具有手性依赖性,而且具有任务依赖性。少
