我们研究了茉莉花茶气味对24名健康志愿者的自主神经活动和情绪状态的影响。我们使用了茉莉花茶的气味，浓度是每个受试者都能检测到的最低浓度，但不会引起任何心理影响。结果表明，茉莉花茶和熏衣草气味在感知强度相近时，与对照组相比，心率显著减慢，高频成分的频谱积分值显著增加（P < 0.05）。在POMS测试中，这些气味产生了平静和充满活力的情绪状态。我们还研究了（R）-（-）-芳樟醇，其主要气味成分之一，在相同浓度的茶，和（S）-（+）-芳樟醇的影响。只有（R）-（-）-芳樟醇能引起心率显著降低（P < 0.05），高频成分增加，产生平静和活力的情绪状态。因此，茉莉花茶气味的低强度对自主神经活动和情绪状态都具有镇静作用，并且（R）-（-）-芳樟醇是其成分之一。可以模仿这些效果。
We investigated the effects of the odor of jasmine tea on autonomic nerve activity and mood states in a total of 24 healthy volunteers. We used the odor of jasmine tea at the lowest concentration that could be detected by each subject but that did not elicit any psychological effects. R-R intervals and the POMS test were measured before and after inhalation of the odors for 5 min. Both Jasmine tea and lavender odors at perceived similar intensity caused significant decreases in heart rate and significant increases in spectral integrated values at high-frequency component in comparison with the control (P < 0.05). In the POMS tests, these odors produced calm and vigorous mood states. We also examined the effects of (R)-(-)-linalool, one of its major odor components, at the same concentration as in the tea, and (S)-(+)-linalool. Only (R)-(-)-linalool elicited a significant decrease in heart rate (P < 0.05) and an increase in high-frequency component in comparison with the controls, and produced calm and vigorous mood states. Thus, the low intensity of jasmine tea odor has sedative effects on both autonomic nerve activity and mood states, and (R)-(-)-linalool, one of its components. can mimic these effects.
