Fundamental Aspects of Effects on Humans of Inhalation of Essential Oils

（1）基于对基本油特性的感知变化的感官测试，一个简单的芳香效果筛选测试被开发出与工作类型相关的工作，即心理工作、物理工作和倾听环境（自然）声音。在评估对一种给予芳香的感知中的变化时，一个感官测试是被雇用的，在一个对幻想的感知被评估为13对形容词的对比。在每种工作类型之前和之后都记录了分数的差异，以及13种描述符评分变化的统计特征是由学生的T测试来测试每种工作类型。在这一研究中测试了16种基本油，包括橙色、明胶、柏树、伯加莫特、Juniper等。这被证实，它揭示了基本油对工作类型的不同的主观看法，导致了一个不同的主观看法。例如，在物理工作后，柏树的抑制产生了比工作前更有利的印象 ... More 在与橙色的情况相比的情况下，在物理工作后产生了一种不受欢迎的印象，与工作前相比。作为精神工作的一部分，也是，抑制juniper似乎在工作后产生一种最受欢迎的印象，而该特征完全相反，用于geranium和orange，同时产生了一种不受欢迎的印象。我们把传感器测试包括在内，但不只是作为对芳香的有效性的筛选测试，但也作为一个分类表的芳香样本，任何人都可以作为彼此的参考。（2）研究对人体对基本油的吸收的生理效应，在感官测试和便携式前置表面电化学（IBVA-EEG）的测量中对人体的生理效应进行了测试，并对它们的关系之间的观察（odor distinctiveness和反应）进行了光学活性的线性工具进行了测试。R-（-）- linalools with specific rotation of （-）-D2D-D2=-15.1 ° was isolated by repeated flash column chromatography from lavender oil，同时（S）-（+）-线性工具与（α）-D2 D2 D2 D2 D2 D2 D2 D2 D2 D2 D2 D20 =0度，含量为R-表格50.9%，（S）-表格49.1%从软木油和商业亚麻油中获得，适当地，通过使用相同的方法。如果使用了抑制剂，则每个都在工作前和工作后10分钟被管理。它发现了linalool使用不同的odor感知和响应的物理测量立体声，不仅与手性依赖有关，而且与任务依赖有关。Less（低）

(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
