Analysis of Volatile Components in Astragalus membranaceus Based on GC-MS Technology
The steam reflux method was used to extract the volatile components of the traditional Chinese medicine Astragalus membranaceus,and the chemical components of the traditional Chinese medicine Astragalus membranaceus were identified using GC-MS technology equipped with the NIST14.L computer spectral library.A total of 56 volatile components were identified from the Astragalus membranaceus,including alkanes,phenols,alkenes,alcohols,esters,ketones,heterocyclic compounds and other compounds,accounting for 99.2％of the total outflow peak area.The volatile components with the highest content were aromatic like phytol(16.47％),plant alcohol(14.73％),eicosane(8.38％),methyl 11-enoate(7.43％),benzyl salicate(6.28％),2,4-heptadienal(6.24％),trans-2-octenal(4.27％),phenylacetaldehyde(3.28％),etc.The results showed that GC-MS technology was able to accurately and quickly identify the volatile oil components of Astragalus membranaceus,providing a certain theoretical basis for the further development and utilization of Astragalus membranaceu.
