  • Artemisia species are widely used as food ingredients and raw material in traditional medicine. However, to date, the secondary metabolites of Artemisia gmelinii Weber ex Stechm. have not been sufficiently investigated. The secondary metabolites of A. gmelinii, which was collected from representative regions in Chungbuk, Gangwon, and Gyeongbuk, were analyzed using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTof MS) combined with an unsupervised principal component analysis (PCA) multivariate analysis. In the loading scatter plot of PCA, significant changes in metabolites were observed between the regions, ten metabolites (3: 5-O-caffeoylquinic acid, 4: 4-O-caffeoylquinic acid, 8: trans-melilotoside, 12: quercetin 3-O-hexoside, 15: 3,4-O-dicaffeoylquinic acid, 17: 3,5-O-dicaffeoylquinic acid, 18: 4,5-O-dicaffeoylquinic acid, 19: syringaldehyde, 20: caffeoylquinic acid derivative, and 23: icariside II) were evaluated as key markers among twenty-five identified metabolites. Interestingly, the contents of the identified marker significantly differed between the three groups. This is the first study to report the presence of marker metabolites and their correlating geographical cultivation in A. gmelinii.

  • The taxonomic status and scientific names of Artemisia gmelinii and its allied taxa have long been debated. To provide correct names and taxonomic status, A. gmelinii and its allied taxa were reviewed in this study based on morphological characters. After a comparison of original descriptions and type specimens, the names of A. freyniana f. discolor and A. freyniana f. vestita used in Korea were recognized as A. sacrorum var. sacrorum and A. sacrorum var. incana, respectively, based on the characters of the trichome on the leaf, the geographical distributions, the chromosome numbers, and the existence of a pinule connection on the exine of the pollen. A. iwayomogi, the scientific name misused as A. gmelinii, was combined and newly named A. sacrorum var. iwayomogi (Kitam.) M. S. Park & G. Y. Chung based on its morphological similarity to the A. sacrorum group. A description, illustration, and key for each of the taxa are provided here.
