The volatile components of wood, bark, and root from Ulmus pumila at room temperature were detected by Gas Chromatography-Ion Mobility Spectrometer (GC-IMS). The volatile components released from the three parts of Ulmus pumila were analyzed and compared using methods including two-dimensional top view, fingerprint, principal component analysis, and molecular weight comparison. The results showed that 37 organic volatiles were identified from 3 parts of Ulmus pumila at room temperature, mainly including alcohols, ketones, aldehydes, esters, acids and other volatile compounds. These 37 volatile substances could be detected in all 3 parts of Ulmus pumila, but there were significant differences in the component content of each part. The molecular weights of the main organic compounds in the 3 parts were between 40 and 110, the molecular weight was small, and they can be released into the environment through the cell wall. Most of them were beneficial bioactive ingredients, which was beneficial to purify the air and improve the environmental quality. [ABSTRACT FROM AUTHOR] |
