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 constituents 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 Province. A comprehensive evaluation system for tree species was established using analytic hierarchy process (AHP). The results showed that the seven broad-leaved plants mainly contained 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 were relatively higher, indicating that from the perspective of BVOCs, these tree species had high value and could be widely used in the construction of health and wellness bases.
