Phytochemical investigation of the MeOH extract of the aerial parts of Geranium eriostemon resulted in the isolation of one triterpene, three furofuran lignans, one syringic acid and four flavonoids. Their chemical structures were characterized by spectroscopic methods to be oleanolic acid (1), (-)-kobusin (2), (-)-eudesmin (3), (+)-magnolin (4), syringic acid (5), quercetin (6), juglanin (7), juglalin (8), and hyperin (9). All compounds (1 - 9) were isolated for the first time from this plant source and the compounds 2 - 4 were reported first from the genus Geranium. Compounds 4 - 6 exhibited moderate cytotoxicity against four human cancer cell lines in vitro using a SRB bioassay.

Vegetative characters (e.g. habitat, root, ramification and habit of stem, phyllotaxy, leaf sape, shape of leaf margin, shape of division and lobe of division, number of division, thick and texture of leaf and shape of stipule) on 35 species of Asian Geranium were reviewed to discussion propriety of taxonomic character and evolutionary trends. Wilfordii group is characterized by three divided leaf, Farreri group was grown a high altitude, and Maculatum group is grouped by life cycle of anneal. Arrangement state of leaf is alternate type G, tripartitum, G. eriostemon, and G. erianthum is thought the more primitive than the other taxon, and regarded as more advanced group the sibiricum group and pseudosibiricum group which divided of leaf deeply. Shape of leaf, division degree of lobes, shape of leaf margin and number of division are considered a good identification characters because width of change are fixed between population.

The moor vegetation of Daeryong-po on Mt. Daeam, east-central Korea was investigated in July 26th-29th, 1989, It was classified into I community group, 4 communities and 5 subcommunities; Sanguisorba tenuifolia var. alba community group, Sphagnum palustre community. Typical subcommunity, Eleocharis mamillata var. cyclocarpa subcommunity, Carex canescense subcommunity, Carex dispalata community, Spiraea salicifolia community, Geranium eriiostemon var. megalanthum community, Arundinella hirta-Phragmites communis subcommunity, Angelica purpuraefolia subcommunity. According to this classification, the actual vegetation map was made. The distribution of vegetation in this moor was divided characteristically into two areas. One was a typical oligotrophic area characterized by S. palustre community. The other was an area having mesotrophic or eutrophic conditions where its original state was disturbed by inflow of soil particles and removal of peat. It this disturbed area, C. dispalata, S. sibiricus, G. eriostemon var. megalanthum, were invaded.

The flora of vascular plants around Chunji and Sochunji in Mt. Baekdu was listed 120 taxa; 31 families, 81 genera, 97 species, 1 subspecies, 21 varieties and 1 form. About endangered wild plants, 2 taxa (Paeonia obovata, Rhododendron aureum) are in class II. 12 taxa were listed as rare and endangered plants; Disporum ovale, Lilium davuricum, Saxifraga punctata, Rosa marretii, Cnidium tachiroei, Bupleurum euphorbioides, Halenia corniculata, Gentiana jamesii, Pedicularis verticillata, etc. 10 taxa were listed as Korean endemic plants; Lilium amabile, Aconitum pseudolaeve var. erectum, Oxytropis anertii for. alba, Valeriana officinalis var. latifolia, Cardamine resedifolia var. morii, Homopteryx nakaiana, Saussurea alpicola, Ligularia jamesii, etc. Specific plants by floral region were total 47 taxa; 3 taxa (Paeonia obovata, Rhododendron aureum, Pedicularis verticillata) in class V, 15 taxa (Lycopodium annotinum, Alnus maximowiczii, Saxifraga punctata, Petasites saxatile, etc.) in class IV, 5 taxa (Spiraea salicifolia, Sanguisorba hakusanensis, Acer ukurunduense, Campanula glomerata var. dahurica, Cacalia adenostyloides) in class III, 18 taxa (Lycopodium chinense, Disporum ovale, Ceologlossum viride var. bracteatum, Betula ermani, Aruncus dioicus var. kamtschaticus, Filipendula multijuga, Geranium eriostemon, Cnidium tachiroei, Ligularia stenocephala, etc.) in class II, 6 taxa (Pinus koraiensis, Cimicifuga simplex, Sanguisorba tenuifolia var. alba, Senecio nemorensis, Cacalia hastata subsp. orientalis, Cirsium pendulum) in class I. Peculiar flora around Chunji is thought to be made by the environmental factors such as wind, temperature and rainfall that influence the plants' growth.
