Components extracted from 7 species and 18 populations of Chrysosplenium in Korea were compared and analyzed using GC-MS analysis. 57 components (${geq}80%$ quality) were identified, of which neophytadiene, palmitic acid and phytol were found at all the taxa. Percentage composition of isolated extracts showed a clear difference in components type and GC-MS profile. On the basis of that result, data matrix was made and cluster analysis using UPGMA was conducted. From the result of cluster analysis, two groups were recombined; one with alternate leaves comprised C. japonicum in Ser. Alternifolia and C. flagelliferum in Ser. Flagellifera and the other with opposite leaves gradationally comprised C. psuedofauriei in Ser. Sinica, C. ramosum in Ser. Oppositifolia and C. sphaerospermum, C. valdepilosum, C. flaviflorum in Ser. Pilosa. These chemotaxonomic results agreed in general with those of existing studies on external morphology and molecular. In conclusion, chemical composition can be an useful characters in understanding the relation analysis among interspecific and intraspecific complex with the help of cluster analysis of 7 species and 18 populations of Chrysosplenium in Korea.
