| 常绿钩吻藤(Gelsemium sempervirens)为常绿木
质藤本，花色金黄，气味香甜，深受百姓喜爱。探究常绿钩吻
藤花香对人体生理心理健康的影响，以期为城市园林绿化中科
学应用提供参考。使用动态顶空套袋法和GC-MS技术对常绿钩
吻藤一天中3个时间段花香挥发物进行采集和检测，采用脑电等
生理指标结合心理量表以获得直观的生理反应和自评变化。共
得到花香挥发物31种，其中上午(9：00—9：30)22种，下午
(13：00—13：30)20种，晚上(18：00—18：30)20种。结
果显示，嗅闻常绿钩吻藤能够有效缓解人的焦虑情绪，提高人
的注意力水平，调节血压。嗅闻常绿钩吻藤存在日变化差异、
闻香时长差异和性别差异，闻香益处的日变化差异可能与挥发
物释放的日变化差异有关。 |

| Abstract: |
| Gelsemium sempervirens is an evergreen woody vine
with golden color and strong sweet smell, which is deeply loved
by people. The impact of the flower fragrance of G. sempervirens
on human physiological and mental health is explored, in order to
provide reference for scientific application in urban landscaping.
Dynamic headspace bagging method and GC-MS technology were
used to collect and detect the volatiles of the flower fragrance of
G. sempervirens in three time periods of a day, and then the human
smell experiment was carried out. EEG and other physiological
indexes combined with psychological scale were used to obtain
intuitive physiological response and self-evaluation changes. A total
of 31 kinds of floral volatiles were detected, including 22 kinds in
the morning (9:00-9:30), 20 kinds in the afternoon (13:00-13:30),
and 20 kinds in the evening (18:00-18:30). Results show that:
smelling G. sempervirens can effectively alleviate people's anxiety,
improve people's attention level, and regulate blood pressure.
There are diurnal variation differences, duration differences, and
gender differences in the aroma benefits of the volatiles from
G. sempervirens. The diurnal variation differences in the aroma
benefits may be related to the diurnal variation differences in the
release of volatiles. |
