Bioactivity guided phytochemical study of the petroleum ether and butanol extracts of Clematis hirsuta resulted in the isolation of 12 compounds. Rat paw edema as a model of acute inflammation was used to evaluate the anti-inflammatory activity of the extracts and the chromatographic fractions. Five known sterols and triterpenes namely: ${\beta}-amyrin$ (1), lupeol (2), ${\beta}-sitosterol$ (3), oleanolic acid (4) and stigmasterol glycoside (5) were isolated from the petroleum ether extract. The n-butanol extract afforded two compounds reported for the first time from natural source: (S)-(+)-dihydro-5-(hydroxymethyl)-2(3H)-furanone (7) and (s)-(-)-5-hydroxymethyl-2(5H)-furanone (8). In addition, anemonin (6), dihydro-4-hydroxy-5-(hydroxymethyl)-2(3H)-furanone (2-deoxy-D-ribono-1,4-lactone) (9), biophenol (cimidahurin) (10), glucose (11) and sucrose (12) were also identified. The structures were determined from spectroscopic data including 1D- and 2D-NMR experiments.

In recent years, the view centered conservation for eco-system is getting important rather than development from human oriented perspective. As a result, the concept "Sustainable development", that is seeking harmony between conservation and development, appeared so that we researched distribution and status of vascular plants a site of project in the Bukkyungnam substation. The main findings from the study is as follows. The vascular plants a site of project in the Bukkyungnam substation area was listed 435 taxa; 93 families, 269 genera, 377 species, 1 subspecies, 51 varieties and 6 forms. Specific plant species by floral region were total 25 taxa; Acer palmatum (Planted species), Asperula lasiantha in Class III, Caryopteris incana, Cirsium schantarense in Class II, 21 taxa (Dryopteris erythrosora, Chloranthus japonicus, Salix glandulosa, Alnus hirsuta, Quercus variabilis, Ulmus parvifolia, Clematis patens, Rubus hirsutus, Euphorbia pekinensis, Cayratia japonica, Grewia biloba var. parviflora, Vaccinium oldhami, Microstegium japonicum, Hosta capitata, Polygonatum falcatum, etc.) in Class I. Based on the list of Korean endemic plants, 10 taxa were recorded; Cephalotaxus koreana, Populus tomentiglandulosa (Planted species), Indigofera koreana, Forsythia koreana (Planted species), Paulownia coreana (Planted species), Asperula lasiantha, Weigela subsessilis, Adenophora triphylla var. hirsuta, Carex okamotoi, Lilium amabile and based on the list of the rare plants by the Forest ResearchInstitute, 2 taxa were recorded in the studied areas; Lilium callosum (Preservation priority order; No. 191), Aristolochia contorta (No. 151). The naturalized plants in this site were 13 families, 22 genera, 28 taxa and naturalization rate was 6.4% of all 435 taxa vascular plants.

This study was carried out to select proper species for early stage replantation in granite forest roads cut-slope. From one to fourteen year elapsed forest roads in eight regional areas of Gyeongsang-do and Jeolla-do, sample plots were selected, and their vegetations and environmental factors were investigated. Soil organic matter, total nitrogen, soil moisture content, and bulk density in the granite weathering soils were below 0.4%, 0.03%, 12.4%, and above 1.2g/$cm^3$, respectively. The result indicated that the soil was not good for plant growth. The environmental factors affecting distribution of species in the granite forest roads were the elapsed year, elevation, and cut-slope aspect. Invaded species with high frequency in the forest road cut-slope ordered Pinus densiflora, Lespedeza bicolor, Rubus crataegifolius, Alnus hirsuta, Youngia denticulata, Patrinia villosa, Artemisia princeps var. orientalis, Zanthoxylum schinifolium, and Dactylis glomerata. Herbs seeded in earth stage such as Dactylis glomerata, Eragrostis curvula, Festuca arundinacea, Lespedeza sp., and Amorpha fruticosa had changed into perennial herbs and shrubs such as Youngia denticulata, Patrinia villosa, Aster scaber, Patrinia scabiosaefolia, Melica onoei, Astilbe chinensis var. davidii, Chrysanthemum zawadskii var. latilobum, Pueraria thunbergiana, Stephanandra incisa, and Clematis apiifolia, and had changed into plants such as Artemisia princeps var. orientalis, Artemisia keiskeana, Miscanthus sinensis, Pinus densiflora, Rhododendron mucronulatum, Rubus crataegifolius, and Zanthoxylum schinifolium according to elapsed year of forest roads. Leguma such as Lespedeza sp., Pueraria thunbergiana, Amorpha fruticosa, etc., herbs such as Artemisia keiskeana, Artemisia princeps var. orientalis, Chrysanthemum zawadskii var. latilobum, Miscanthus sinensis, etc., and woody plants such as Pinus densiflora, Rubus crataegifolius, Rhododendron mucronulatum, etc., with foreign herbs were considered as proper species for replantation in granite forest road cut-slope.
