This study was carried out objectively to analyze the distributing flora for the conservation of natural environment and to construct the database in Mt. Joryeong, Chungcheongbuk-do, Korea. The period of survey was from November, 2004 to September, 2005, and the routes were A (Recreation $forest{\sim}Shinseon-bong$), B $(Shinseon-bong{\sim}Mapae-bong)$, C(Joryeong 3rd $gateway{\sim}Mapae-bong$), and D $(Yongseong-gol{\sim}Gitdae-bong)$. The vascular plants were summarized as 341 taxa; 85 families, 219 genera, 299 species, 36 varieties, and 6 forma. The rare and endangered plants designated by Korea Forest Service were 3 taxa; Paeonia japonica, Viola albida, and Rhododendron micranthum. The Korean endemic plants were 9 taxa; Cephalotaxus harringtonia, Salix caprea, Deutzia coreana, Spiraea prunifolia for. simpliciflora, $Lespedeza{\times}tomentella$, Vaccinium koreanum, Salvia chanroenica, Weigela subsessilis, and Cirsium setidens. And in the results of survey on resource plants, we confirmed 171 taxa of ornamental plants (50.1%), 222 taxa of edible plants (65.1%), 237 taxa of medicinal plants (69.5%) and 146 taxa of other useful plants (42.8%).

A novel purification method was developed for producing homoharringtonine from Cephalotaxus koreana, to guarantee high purity and yield. Our simple, efficient procedure for isolating and purifying homoharringtonine from C. koreanabiomass consisted of solvent extraction, synthetic adsorbent treatment, low-pressure chromatography, followed by high performance liquid chromatography (HPLC). The use of active clay treatment and silica gel low-pressure chromatography in the pre-purification process allowed for the rapid, efficient separation of homoharringtonine from interfering compounds and dramatically increased the yield and purity of crude homoharringtonine for high-performance liquid chromatography (HPLC) purification steps compared with alternative processes. Homoharringtonine could be obtained simply with high yield and purity from biomass using this purification method, while minimizing solvent use and the scale and complexity of HPLC operations for homoharringtonine purification. Purified homoharringtonine was identified and characterized.

The purpose of this study was to investigate the distribution of vascular plants growing at the Mt. Daedun provincial park area in the boundary between Nonsan-si, Geumsan-gun, Chungcheongnam-do and Wanju-gun, Jeollabuk-do, Korea. We collected the vascular plants 9 times from May 2016 to July 2017. The flora of Mt. Daedun was classified as a total of 434 taxa comprising of 95 families, 278 genera, 388 species, 3 subspecies, 38 varieties and 5 forma. Among them, the endemic plants in Korea that the investigation found were 11 taxa including Broussonetia kazinoki Siebold, Clematis trichotoma Nakai, Thalictrum actaefolium var. brevistylum Nakai, etc. It also found rare plant species, as designated by the Korea Forest Service were 6 taxa including 5 grade LC taxa such as Eranthis stellata Maxim., Viola albida Palib., and Scopolia japonica Maxim. and 1 grade DD taxa, Scrophularia koraiensis Nakai. The special floristic plants were a total of 35 taxa such as 9 taxa in degree III (Eranthis stellata Maxim., Stewartia pseudocamellia Maxim., Acer palmatum Thunb., etc.), 7 taxa in degree II (Equisetum hyemale L., Potentilla dickinsii Franch.&Sav., Viola orientalis (Maxim.) W. Becker, etc.) and 19 taxa in degree I (Dryopteris crassirhizoma Nakai, Cephalotaxus koreana Nakai, Ulmus parvifolia Jacq., etc.) to provide basic data. No taxa in grade V or IV were found. The naturalized plants were 34 taxa including Rumex acetosella L., Phytolacca americana L. and Chenopodium album L., and the percentage of urbanization index was 10.6% while the naturalized plant index was 7.7%.

The purpose of this study was to find a basic theory about Korean traditional planting pattern by analyzing a characteristic of planting and planted species in Haein, Tongdo and Songkwang Temples. The results are as follows. The planted species in three-treasure temples were 129 taxa; 57 families, 96 genera, 110 species, 12 varieties and 7 forma. The species related in Buddhism were Viburnum sargentii for. sterile, Hydrangea macrophylla for. otaksa and Musa basjoo. They are related in plant form and Buddhist ceremony. The results of forms were 34.1% in trees, 33.3% in shrubs, 3.9% in vine and 28.7% in herbage. The results of leaf fall were 56 taxa in broad-leaved deciduous trees, 27 taxa in broad-leaved evergreen trees and 14 taxa in needle-leaved evergreen trees. The native species were 32 taxa in Haein Temple, 27 taxa in Tongdo Temple and 44 taxa in Songkwang Temple. And the exotic species were 20 taxa, 28 taxa and 44 taxain the Haein, Tongdo and Songkwang Temples, respectively. In the results of analyzing the characteristics of planting, in the case of Haein Temple, Abies holophylla was linearly planted in Yiljumun, and Magnolia denudata was single planted in plant stairs of Haetalmun. In the case of plant stairs of Jeokmukdang, Cephalotaxus koreana was planted at regular intervals. In the case of Tongdo Temple, Celtis sinensis, Zelkova serrata and so forth were planted in Yiljumun, and Phyllostachys nigra was planted in form of screen planting in Youngsanjeon. The form of Hwanghwagak was a planting of symmetry in the center of a building, and the one of Daekwangmyyeongjeon was a mixed planting. The regular planting pattern was not shown in Yiljumun of Songkwang Temple. In the case of Dosungdang, Corunus officinalis was linearly planted in the west. In the case of Gwaneumjeon, Juniperus chinensis var. globosa and Camellia japonica were planted in symmetry. The old aged trees were planted in front of specimens planted in front of Daewoongbojeon.
