  • 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.

  • 쥐손이풀속(subgenus Geranium) 35분류군에 대하여 외부형태학적 형질인 생육지, 뿌리, 줄기의 습성과 분지 형태, 엽서, 엽형, 엽연의 모양, 잎열편과 소열편의 형태, 열편의 갯수, 잎의 두께와 엽질 및 탁엽의 형태 통의 영양형질을 조사하고, 이들의 분류형질로서의 타당성 및 진화경향성을 논의하였다. 잎이 3열편으로 갈라지는 특징에 의해 Wilfordii군이, 생육지가 고산지역인 Farreri군이 나누어지며, 일년생인 특징에 의해 Maculatum군이 구분되어진다. 잎의 배열상태가 호생인 G, tripartitum, G. eriostemon, 및 G. erianthum이 나머지 분류군보다. 원시적이고, 열편이 깊게 갈라진 Sibiricum군과 Pseudosibiricurn군이 보다 분화한 분류춘이라고 생각된다. 본 분류군에서는 잎의 엽형과 소열편의 분 지정도 및 엽연의 모양과 열편의 갯수 등은 개체군 사이에서도 변이의 폭이 일정해 종을 구분하는 좋은 식별형질이라고 사료된다.

  • 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.
