The phytochemical study of the aerial parts of Artemisia japonica ssp. littoricola (Asteraceae) led to the isolation of two acetylenic compounds, (3R)-dehydrofalcarinol (2) and (3R)-dehydrofalcarindiol (6), two sesquiterpenes, $1{\beta}$, $6{\alpha}$-dihydroxy-4(15)-eudesmene (5) and oplodiol (8), and four phenolic compounds, eugenol (1), vanillin (3), 3'-methoxy-4'- hydroxy-trrans-cinnamaldehyde (4) and p-hydroxyacetophenone (7). Their structures were determined by chemical and spectroscopic methods.

This study aims to investigate the flora and the vegetation of Dokdo (Dongdo). The vegetation types were investigated by the Z-M school method. A total of 44 vascular plant taxa belonging to 24 families, 41 genera, 36 species, and 11 varieties are recognized in Dongdo, Dokdo. In this study, we confirmed four species, Chenopodium serotinum, Chelidonium majus var. asiaticum, Bromus japonicus, Elymus sibiricus, that had not been previously reported. The biological type of Dokdo was determined to be $Th-D_4-R_5-e(b)$ type. Two main vegetation groups which were established in a rocky area with little soil development and in a developed soil layer, along the development of soil layer have been distinguished and classified into five communities. The former was composed of 1 community; Aster spathulifolius-Sedum oryzifolium community. The latter was composed of 4 communities; Agropyron tsukusiense var. transiens community, Festuca rubra-Artemisia japonica ssp. littoricola community, Miscanthus sinensis community, and Artemisia princeps community.
