Britt., is recognized as both a medicinal substance and an edible ingredient in China, with its market demand steadily rising. The nutritional value of Perillae Folium varies markedly across different geographical origins, posing a constraint on its further industrial development. To date, there remains a paucity of robust and reliable approaches for tracing the geographical origin of Perillae Folium samples. This study employed headspace gas chromatography ion mobility spectrometry to profile VOCs in Perillae Folium, revealing that those originating from Hunan province contained comparatively higher volatile organic component levels. Subsequently, a total of 54 volatile organic components were putatively identified in Perillae Folium, and six featured VOCs including 2\u2010decanone, 3\u2010octanol, 2,6\u2010dimethyl\u20105\u2010heptenal, 3\u2010methyl\u20103\u2010buten\u20101\u2010ol, ethyl 3\u2010hydroxybutyrate, and 1\u2010(1\u2010methylethyl)\u20104\u2010methylbenzene were identified. Eight machine learning classifiers were built based on the selected featured VOCs. Among the eight models, the linear and polynomial kernel support vector machines achieved the highest predictive accuracies, both exceeding 90%, indicating their strong potential for practical application. This study provides a reference for the study of volatile organic components in Perillae Folium from different geographical origins, and offers a simple, accurate, and reliable method for distinguishing Perillae Folium from these regions.\n                  <\/jats:p>","DOI":"10.1002\/jssc.70525","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T07:48:28Z","timestamp":1788940108000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Machine Learning\u2010Assisted Headspace Gas Chromatography Ion Mobility Spectrometry for Characterization and Geographical Authentication of Perillae Folium"],"prefix":"10.1002","volume":"49","author":[{"given":"Chenyu","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Chemistry The University of Hong Kong  Hong Kong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Yue","sequence":"additional","affiliation":[{"name":"School of Pharmacy Shandong University of Traditional Chinese Medicine  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruizi","family":"Shan","sequence":"additional","affiliation":[{"name":"School of Pharmacy Shandong University of Traditional Chinese Medicine  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongjing","family":"Dong","sequence":"additional","affiliation":[{"name":"Shandong Engineering Research Center for Innovation and Application of General Technology For Separation of Natural Products Shandong Analysis and Test Center Qilu University of Technology (Shandong Academy of Sciences)  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Pharmacy Shandong University of Traditional Chinese Medicine  Jinan China"},{"name":"Shandong Engineering Research Center for Innovation and Application of General Technology For Separation of Natural Products Shandong Analysis and Test Center Qilu University of Technology (Shandong Academy of Sciences)  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scienta.2020.109682"},{"key":"e_1_2_9_3_1","volume-title":"Pharmacopoeia of the People's Republic of China","author":"Chinese Pharmacopoeia Commission","year":"2020"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12272\u2010015\u20100582\u2010y"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.16305\/j.1007\u20101334.2013.09.029"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.2c03104"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2021.131834"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.16498\/j.cnki.hnnykx.2023.003.004"},{"key":"e_1_2_9_9_1","first-page":"2207","article-title":"Qualitative and Quantitative Analysis of Characteristic Components of Perillae Folium From Different Regions by Pattern Recognition Combined With Muti\u2010Component Analysis","volume":"51","author":"Li D.","year":"2020","journal-title":"Chinese Traditional and Herbal Drugs"},{"key":"e_1_2_9_10_1","first-page":"3380","article-title":"Evaluation of PK Type Perilla Frutescens Leaf Quality From Different Origins Based on GC\u2010MS Fingerprint and Retention Index Method","volume":"47","author":"Chen L.","year":"2025","journal-title":"Chinese Traditional Patent Medicine"},{"key":"e_1_2_9_11_1","first-page":"153","article-title":"Identification of Perilla Frutescens (L.)
