摘要
小叶栀子作为一种常用的园林植物,开花期间散发着浓郁的香气,具有美化环境、杀菌抗菌以及消炎杀虫等功效,在园艺疗法中具有一定的疗愈作用。为探究嗅闻小叶栀子香气给人体带来的健康效益,通过动态顶空套袋法和GC-MS技术采集鉴定小叶栀子花叶枝条挥发物成分,以脑电波、血压和心率作为生理指标,心境状态量表作为心理评估依据开展试验。结果表明:1)盛花期小叶栀子花叶枝条挥发性有机物有84种,主要成分为萜烯类物质和酯类物质,一天内小叶栀子挥发物释放总量呈上升趋势,在下午13∶00-13∶30挥发物种类(71种)最丰富;2)小叶栀子挥发物能极显著(P<0.01)降低人体收缩压和心率,不显著(P>0.05)降低舒张压,不显著(P=0.05)提升专注力和反应力,极显著(P<0.01)缓解焦虑紧张情绪;3)小叶栀子的健康效益存在性别差异和时段差异,嗅闻小叶栀子花后,女性更能提升专注力、降低心率,男性更能集中思维、降低血压;在下午(13∶00-17∶00)和晚上(18∶00-22∶00)嗅闻小叶栀子花后人体血压降低最显著,下午(13∶00-17∶00)脑电波θ波变化最剧烈。因此,小叶栀子花具有良好的人体生理、心理健康恢复效果,建议在学习、工作等场所周围多种植小叶栀子花。
As a commonly used ornamental plant,Gardenia Jasminoides J.Ellis emits a rich aroma and has functions of such as environment beautification,bacteria killing,inflammation reduction,and insects killing.It also plays a certain therapeutic role in horticultural therapy.In order to explore the specific health benefits of its aroma to the human body,this paper collects and identifies the volatile components of G.Jasminoides J.Ellis through dynamic headspace bagging method and GC-MS technology,and carries out experiment using brain waves,blood pressure and heart rate as physiological indicators and mood state scale(POMS)as the psychological base.The results show that:1)During the blooming period,there are 84 types of volatile organic compounds in G.Jasminoides J.Ellis,mainly composed of terpenes and esters.The total amount of volatile compounds released during the day shows an increasing trend,while volatile compounds are the most abundant in type(71 types)between 13∶00 and 13∶30 in the afternoon;2)The volatile compounds of G.Jasminoides J.Ellis can reduce human systolic blood pressure and heart rate significantly(P<001),insignificantly reduce diastolic blood pressure(P>005)and improve concentration and reflexes(P=005),and significantly alleviate anxiety and tension(P<001);and 3)There are gender differences and duration differences in the health benefits of G.Jasminoides J.Ellis.After smelling the aroma,women can improve their concentration and lower their heart rate,while men can concentrate more and lower their blood pressure.During the afternoon(13∶00-17∶00)and evening(18∶00-22∶00),smelling the aroma leads to the most significant decrease in human blood pressure.In the afternoon(13∶00-17∶00),theθwave changes the most acutely.It is considered that G.Jasminoides J.Ellis has a good effect on the recovery of human physiological and psychological health.It is suggested that G.Jasminoides J.Ellis should be planted near the places for such as study and work.
