. The present work investigates the effect of essential oil from the twigs of on electroencephalographic (EEG) activity of human brain in order to understand the influence of binasal and uninasal inhalations. . To accomplish this study, the essential oil from the twigs of (AEO) was isolated by steam distillation and the EEG readings were recorded using QEEG-8 system from 8 grounding electrodes according to the International 10-20 System. . D-Limonene (25.29%), bornyl acetate (19.31%), camphene (12.48%), -pinene (11.88%), -pinene (6.45%), and eudesm-7(11)-en-ol (5.38%) were the major components in the essential oil. In the EEG study, the absolute alpha (left frontal and right parietal) and absolute fast alpha (right parietal) values significantly increased during the binasal inhalation of AEO. In the uninasal inhalation, absolute beta and theta values decreased significantly, especially in the right frontal and left and right parietal regions. The results revealed that the AEO produced different EEG power spectrum changes according to the nostril difference. . The changes in EEG values due to the inhalation of AEO may contribute to the enhancement of relaxation (binasal inhalation) and alertness/attention (right uninasal inhalation) states of brain which could be used in aromatherapy treatments.
本研究调查了[植物名称]嫩枝精油对人脑脑电图（EEG）活动的影响，以了解双侧鼻腔和单侧鼻腔吸入的影响。为完成本研究，通过水蒸气蒸馏法分离出[植物名称]嫩枝精油（AEO），并根据国际10-20系统，使用QEEG-8系统从8个接地电极记录EEG读数。D-柠檬烯（25.29%）、乙酸龙脑酯（19.31%）、莰烯（12.48%）、α-蒎烯（11.88%）、β-蒎烯（6.45%）和桉叶-7(11)-烯-醇（5.38%）是该精油的主要成分。在EEG研究中，双侧鼻腔吸入AEO期间，绝对α波（左额叶和右顶叶）和绝对快α波（右顶叶）值显著增加。在单侧鼻腔吸入时，绝对β波和θ波值显著降低，尤其是在右额叶以及左、右顶叶区域。结果表明，AEO根据鼻孔差异产生不同的EEG功率谱变化。吸入AEO引起的EEG值变化可能有助于增强大脑的放松状态（双侧鼻腔吸入）和警觉/注意力状态（右侧单侧鼻腔吸入），这可用于芳香疗法治疗。
