The present study was carried out to investigate the effect of exposure of Cambodian black pepper essential oil on the human electroencephalographic (EEG) activity. In the EEG study, 20 men and 20 women healthy volunteers participated. The EEG readings were recorded from 32 electrodes placed on the scalp according to the International 10‐20 system and 25 EEG indices were analyzed. The essential oil of black pepper mainly contains β‐caryophyllene (30.53%), 3‐carene (19.85%), limonene (14.26%), β‐pinene (9.45%), and α‐pinene (5.25%). The EEG data showed that the exposure of black pepper essential oil exhibited different brain wave activity according to the gender. In women, a significant increase of spectral edge frequency 50% of alpha at C4 region was observed due to the exposure of black pepper essential oil. In the case of men, relative gamma, the ratio of sensorimotor rhythm to theta, spectral edge frequency 50%, spectral edge frequency 90%, and spectral edge frequency 50% of alpha significantly increased during the exposure of black pepper essential oil. The result revealed that the gender variation plays a major role in the EEG activity of black pepper essential oil and the exposure of black pepper essential oil may improve the cognitive functions.

来自柬埔寨磅湛的黑胡椒精油暴露对脑电图活动的性别变化

本研究旨在调查柬埔寨黑胡椒精油暴露对人体脑电图（EEG）活性的影响。在脑电图研究中，有20名男性和20名女性健康志愿者参加。根据International 10-20系统，从放置在头皮上的32个电极记录了EEG读数，并分析了25个EEG指数。黑胡椒精油主要包含β-石竹烯（30.53％），3-烯（19.85％），柠檬烯（14.26％），β-pine烯（9.45％）和α-pine烯（5.25％）。脑电数据表明，黑胡椒精油的暴露根据性别表现出不同的脑电波活动。在女性中，由于黑胡椒精油的暴露，在C4区域观察到光谱边缘频率α的50％显着增加。对于男性，相对伽玛，在黑胡椒精油暴露期间，感觉运动节律与θ的比率，光谱边缘频率50％，光谱边缘频率90％和光谱边缘频率50％的α显着增加。结果表明，性别差异在黑胡椒精油的脑电活动中起主要作用，而黑胡椒精油的暴露可改善其认知功能。
