针叶树种释放VOCs成分与潜在作用分析OA

In order to investigate the effects of volatile organic compounds(VOCs)emitted into the natural environment and their po-tential effect in promoting mental health,the dynamic headspace sampling method combined with gas chromatography-mass spec-trometry(GC-MS)was employed to collect gases and identify VOCs compounds emitted by Pinus tabulaeformis,Platyphelus orienta-lis,and Juniperus chinensis.Additionally,network pharmacological approaches were utilized to assess the relationships between the VOCs emitted by these trees species and the genetic targets associated with human diseases.The findings indicated that the main components of VOCs emitted by the three coniferous tree species included α-pinene,β-pinene,limonene,and dimethyl phthalate,with terpenoids being the predominant category of volatile substances.There were differences in the types and contents of VOCs emit-ted among the coniferous tree species.Substances such as linalool emitted by Pinus tabulaeformis and 9-octadecenoic acid emitted by Platycladus orientalis and Juniperus chinensis corresponded to the most significant potential targets for depression.The primary ac-tive components of VOCs emitted by coniferous tree species could contribute to antidepressant by modulating the neuroactive ligand-receptor interaction pathway,neurodegenerative disease pathways,and calcium ion signaling pathways.This study provided a theo-retical foundation for further elucidating the mechanisms through which VOCs emitted by coniferous species promote mental health.
