OBJECTIVES
The present study aimed to investigate the effect of inhalation of essential oil (EO) and supercritical carbon dioxide extract (SC-CO) from the root of A. gigas on human electroencephalographic (EEG) activity.
MATERIALS AND METHODS
For this purpose, the EO was obtained from the root of A. gigas by steam distillation and SC-CO was obtained at 50 °C and 400 bar for 1 h. The EEG readings were recorded using the QEEG-8 system from 8 electrode sites according to the International 10-20 system.
RESULTS
In the EEG study, the absolute low beta (left temporal and left parietal) activity significantly increased during the inhalation of EO. In the case of SC-CO inhalation, there was no significant change in absolute waves.
CONCLUSION
The results revealed that the EO of A. gigas root produced significant changes in the absolute low beta activity and these changes may enhance the language learning abilities of human brain.
目的
本研究旨在探讨吸入巨大牛樟根的精油（EO）和超临界二氧化碳提取物（SC-CO）对人体脑电图（EEG）活动的影响。
材料与方法
为此，通过水蒸气蒸馏从巨大牛樟根中提取精油，在 50°C 和 400 巴下提取 1 小时获得 SC-CO。EEG 读数使用 QEEG-8 系统根据国际 10-20 系统从 8 个电极部位记录。
结果
在 EEG 研究中，EO 吸入时左颞叶和左顶叶的绝对低β（left temporal and left parietal）活动明显增加。SC-CO 吸入时，绝对波没有明显变化。
结论
结果表明，巨大牛樟根的 EO 对绝对低β活动产生了显著的变化，这些变化可能增强了人脑的语言学习能力。
