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. officinalis、
P. 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.
