In the analysis of chemotype relationship among Korean Chrysanthemum species, the volatile compounds in the leaves of 15 taxa were analyzed and identified by gas chromatograph/mass spectrometry. Principal component analysis and cluster analysis used for the grouping based on the volatile compounds. Fifteen taxa of Charysanthemum species were categorized into three groups. Groups I and II included higher ketones than Group III. Group I had five C. zawadskii subspecies: acutilobum, acutilobum var. tenuisectum, acutilobum var. alpinum, lucidum, and coreanum. Five C. zawadskii subspecies were analyzed with main volatile compounds of D-limonene and m-thymol. Group II consisted of four C. zawadskii subspecies including naktongense, yezoense, latilobum, and latilobum var. leiophyllum, and one species C. makinoi. They consisted of main compounds of linalool, cis-chrysanthenol, eugenol, and chrysanthenone. Group III included five C. indicum species and related species: C. indicum, var. albescens, var. acuta, C. boreale, and C. lineare. The present study was able to classify volatile compounds of Korean Chrysanthemum species attributable to major compounds, such as hydrocarbons (sabinene, cymene, β-selinene), alcohols (1-octen-3-ol, cis-chrysanthenol, hinesol), ketones (chrysanthenone, camphor), and esters (cis-sabiene hydrate, trans-chrysanthenyl acetate).
