Objective：To understand the difference of cumulative content and species of volatile organic compounds(VOCs) in five different species of Chrysanthemum morifolium Ramat..Methods：In this study， five different species of Chrysanthemum morifolium Ramat.，namely，Jin si huang ju，Huang ju，Hang baiju， Boj u， and Gong ju.The differences and variations of the fingerprints of volatile organic compounds (VOCs) in different species of Chrysanthemum morifolium Ramat.were studied by headspace-gas chromatography-ion mobility spectro s-copy(HS-GC-IMS) ， combined with cluster analysis and relation-ship matrix in the form of data visualization.Results：There were significant differences in VOCs among different varieties of Chrysanthemum mori folium Ramat.(P＜0.05) ， and the similar-ity between them was less than 70%， and all of them had their own unique volatile organic components； the five kinds of Chrys-an the mum mori folium Ramat.in the order of high to low VOCscontent were：Go nj u， Jin shi Huang ju， Huang ju， Boj u， and Hang baiju.Conclusion：HS-GC-IMScanmakeup for theshort-comings of conventional VOCs detection， making detection more data basis and support， and providing theoretical basis and data support for the differentiation and identification of different varie-ties of Chrysanthemum mori folium Ramat..
