As part of our systematic study for Korean Compositae plants, we have studied Saussurea nutans, collected at Gangwon Province on August 2001. Phytochemical studies on various species of genus Saussurea have resulted in the isolation sesquiterpene, triterpene and flavonoid$\^$1)/. S. nutans has been used for the treatment of rheumatic arthritis and dysmenorrhea in the Chinese folk medicine$\^$2)/. However, chemical constituents of this plant have not been reported until now. The MeOH extract of the aerial parts of this source was solvent fractionated into n-hexane, methylene chloride, ethyl acetate and BuOH soluble portions. (omitted)

Seven terpenoids, trans-phytol (1), ${\alpha}-spinasterol$ (2),${\beta}-sitosterol$ (3), oleanolic acid (4), traxasterol (5), ${\alpha}-spinasterol\;3-O-{\beta}-D-glucopyranoside$ (8), ${\beta}-spinasterol\;3-O-{\beta}-D-glucopyranoside$ (9), and three glycerides, 3-O-(9Z, 12Z, 15Z-octadecatrienoyl) glycerol (6), 3-O-(9Z, 12Z-octadecadienoyl) glycerol (7), 1, 2-O-(9Z, 12Z, 15Z-dioctadecatrienoyl)-3-O-${\beta}$- D-galactopyranosyl glycerol (10) were isolated from n-hexane fraction of the aerial parts of Saussurea nutans which was used as Korean traditional medicine to σeat rheumatic arthritis and dysmenorrhea. Their structures were established by chemical and spectroscopic methods.

This study was carried out to investigate the vascular plants of the construct-reserved sites of ecological forests in Deokdong-ri, Baekwoon-myeon, Jecheon-si, and Chungcheongbuk-do, Korea and the period was from March to October, 2004. The results of surveying the vascular plants were recorded as 371 taxa; 83 families, 238 genera, 324 species, 44 varieties and 3 forma. There were 4 species of rare and endangered plants as designated by Korea Forest Service; Eranthis stellata, Paeonia japonica, Viola albida and Scopolia japonica. There were 9 species of Koreanendemic plants Pseudostellaria coreana, Melandryum seoulense, Clematis trichotoma, Deutzia coreana, Spiraea prunifolia for. simpliciflora, Ajuga spectabilis, Weigela subsessilis, Cirsium setidens and Saussurea nutans. Ten species of naturalized plants were observed Panicum dichotomiflorum, Rumex crispus, Amaranthus retroflexus, Lepidium apetalum, Trifolium repens, Oenothera Jamayckiana, Erigeron annuus, Erigeron canadensis, Bidens frondosa and Taraxacum officinale. In the results of analysis by floristic region, the specific plants were summarized as 52 taxa; 30 families, 47 genera, 49 species and 3 varieties.

The flora of Bongamsa (Temple) area, Mungyeong were listed 552 taxa; 99 families, 303 genera, 468 species, 1 subspecies, 70 varieties and 13 forms. Based on the rare plants (IUCN), total 12 taxa; Crypsinus hastatus (Polypodiaceae), Eranthis stellata (Ranunculaceae), Cnidium tachiroei (Umbelliferae), Monotropa hypopithys (Pyrolaceae), Rhododendron micranthum (Ericaceae), Salvia chanroenica (Labiatae), Gastrodia elata (Orchidaceae), etc. Based on the endemic plants, total 11 taxa; Asarum chungbuensis, Aconitum pseudolaeve, Corydalis maculata, Lonicera subsessilis, Aster koraiensis, Saussurea seoulensis, etc. Based on the specific plants by floral region were total 48 taxa (8.7% of all 552 taxa of vascular plants); 2 taxa in class V, 5 taxa (Cimicifuga heracleifolia, Wistaria floribunda, Elsholtzia angustifolia, etc.) in class IV, 10 taxa (Betula davurica, Spiraea chinensis, Acer barbinerve, Vaccinium koreanum, Syringa reticulata var. mandshurica, etc.) in class III, 7 taxa (Potentilla dickinsii, Viola orientalis, Ostericum melanotilingia, Melica nutans, Veratrum parulum, etc.) in class II, 24 taxa (Camptosorus sibiricus, Cephalotaxus koreana, Betula schmidtii, Ilex macropoda, Tilia amurensis, Triadenum japonica, Lobelia sessilifolia, etc.) in class I. Based on the naturalized plants, total 21 taxa (Silene armeria, Oenothera lamarckiana, Symphytum officinale, Erechtites hieracifolia, etc.) and naturalization rate was 3.8% of all 552 taxa of vascular plants. The flora of importance in the Bongamsa, rare plants were Crypsinus hastatus, Eranthis stellata, Gastrodia elata, Monotropa uniflora, Monotropa hypopithys, Rhododendron micranthum and Cnidium tachiroei, Iris ensata var. spontanea in intermediate marsh and alien species classify into planted species of Bongamsa, area for investigation of afforestation and artificial forests, introduced of naturalized plants.
