7种阔叶植物芬多精成分研究及评价

Study on the composition and AHP evaluation of phytoncidere in seven broad-leaved plants

  • 摘要: 采用植物动态顶空套袋采集法和热脱附-气质联用(TDS-GC-MS)技术,以四川地区7种阔叶植物(厚朴Houpoea officinalis、珙桐Davidia involucrata、楠木Phoebe zhennan、银杏Ginkgo biloba、水杉Metasequoia glyptostroboides、油樟Cinnamomum longepaniculatum、垂柳Salix babylonica)作为研究对象,分析测定其释放的芬多精成分和含量,结合层次分析法(AHP)建立树种的综合评价体系对释放的植物挥发性有机物(BVOCs)做出科学评价。结果表明:7种阔叶植物芬多精成分主要包括萜烯类、烷类、醇类、醛类、酯类、酮类等六类挥发性有机物,但含量各不相同;综合评价排序为厚朴>楠木>油樟>珙桐>银杏>水杉>垂柳,油樟、厚朴、楠木得分较高,说明从 BVOCs 的角度来看这些树种具有较高的价值,可在康养基地建设中广泛应用。

     

    Abstract: The dynamic headspace bagging collection method and thermal desorption gas chromatography-mass spectrometry (TDS-GC-MS) technology were used to analyze and determine the components and contents of fenugreek released from seven broad-leaved plants (Houpoea officinalis, Davidia involucrata, Phoebe zhennan, Ginkgo biloba, Metasequoia glyptostroboides, Cinnamomum longepaniculatum, Salix babylonica) in Sichuan region. A comprehensive evaluation system for tree species was established using Analytic Hierarchy Process (AHP). The results showed that the seven broad-leaved plants mainly contain six types of volatile organic compounds, including terpenes, alcohols, esters, aldehydes, ketones, and alkanes, with varying levels of content.The ranking of the comprehensive evaluation scores for the seven broad-leaved plants was as followed: H. officinalis > P. zhennan > C. longepaniculatum > D. involucrata > G. biloba> M. glyptostroboides > S. babylonica. The evaluation scores of H. officinalisP. zhennan and C. longepaniculatum are relatively higher, indicating that from the perspective of BVOCs, these tree species have high value and can be widely used in the construction of health and wellness bases.
