月桂（Laurus noblis L.）（月桂）主要用作烹饪中的香料，并且通过蒸汽蒸馏叶获得的精油用作食品、药物和化妆品中的添加剂。本文研究了紫茎泽兰叶片挥发性物质的影响。noblis在不同剂量（低剂量和高剂量组）对视觉辨别任务中的警觉性能的影响。通过吸入L. noblis，在低剂量组中防止了对照组中发现的真实命中率的降低。高剂量组在与负性情绪相关的主观效应方面的得分高于低剂量组。同时，两组均显示出刺激循环的生理效应。这些结果表明，挥发性物质的释放，从L。低浓度的Noblis可用于保持高水平的警觉性表现，例如通过改善生理唤醒而不引起负面情绪的有害表现影响的真实命中率。
The leaves of Laurus noblis L. (laurel) are mainly used as a spice in cooking, and the essential oil obtained by steam distillation of the leaves is used as an additive in foods, drugs and cosmetics. We investigated the effect of the volatiles emitted from the leaves of L. noblis at different doses (low-dose and high-dose groups) on vigilance performance in a visual discrimination task. By inhaling volatiles of the leaves of L. noblis, the decrease of the rate of true hits found in the control group was prevented in the low-dose group. The high-dose group showed higher scores than the low-dose group for subjective effects related to negative emotion. Meanwhile, both groups showed physiological effects suggesting stimulation of circulation. These findings suggest that the volatiles emitted from the leaves of L. noblis at low concentration could be utilized to maintain a high level of vigilance performance, such as the rate of true hits by improving physiological arousal without incurring the detrimental performance effects of negative emotion.
