The leaves of Cedrela sinensis have been used for food at south area in Korea and oriental medicine for treating enteritis, dysentery and itch. Kaempferol, methyl gailate, quercetin, afzelin, quercitrin, isoquercitrin and rutin were isolated from the leaves of this plant and characterized by spectral data. These compounds are reported for the first time from this plant.

Hepatitis, liver cirrhosis and liver cancer caused by viral infection are among the most prevalent causes of death in Korea. Several medicines have been in use despite their nonsatisfactory effects on these disease. Some herbal medicines put to use recently have not shown beneficial effects, either. This paper evaluates the effects of extracts from 10 traditional Korean herbal medicines on rats with hepatic damage induced by galactosamine. Rubus coreanus showed an anti-inflammatory effect as shown on the data of activities of serum transaminases.

This experiment was investigated from March 20 to September 20, 1960. It was investigated chlorophyll, carotene and ascorbic acid contents of edible plants in Korea, 64 with 132 species belonging to 62 families for the ascorbic acid and 116 species on the 64 families for the chlorophyll and carotene content. Carotene content varies with chlorophyll although the ratio of chlorophyll to carotene was not so high as that obtained by Beak and Redman (1). Where the chlorophyll content is abundant, it appears that the amounts of carotene and ascorbic acid are also plenty.

Many monoterpen-erivatives are contained in edible plants. Some monoterpen-derivatives have been assessed as negative factors in the food safety. Among them thuone and 4-caranone are important toxic constituents of many plant essential oils. In this study, convenient detection methods of thujone and 4-caranone in oil were developed. The colour reactions of toxic thujone and 4-caranone were performed in oder to detect those in foods and oils. Sodium pentacyanonitrosylferrate (II) react with thujone to produce thujzoximinocarboxylic acid which becomes the six ligand in the ferrate complex (red colour reaction for thujone). Sodium pentacyanonitrosylferrate (II) cleaves 4-caranone to the red ferrate complex of caranketonic acid.

The articles, published in the Journal of Korean Forest Society from Volume 1 (1962) to Volume 102 (2013), were investigated for the research trend analysis about forest plants for special purposes, i.e., edible plants, medicinal plants, feed resources, landscape plants, fiber plants, industrial usage, bee plants, bioenergy/phytoremediation uses, dye materials, and rare/endangered/endemic plants. These research articles were classified again based on the contents of research into following categories - habitat environment, ecology, physiology, propagation, silviculture (including planting and tending), genetics and breeding, identification, pest and disease control, animal-related research, components analysis and extracts, vegetation survey, biotechnology, management, recreation and forest healing, and research review. Among the total 2,433 articles published, 611 (25.1%) were related to plants for special usage or purposes. The highest frequency (14.9%) in publications was found in the field of silviculture followed by physiology, propagation, identification, and genetics and breeding, respectively. On the bases of usage, edible plants showed higher frequency (26.5%) than others, followed by industrial purpose, bioenergy/phytoremediation usage, landscape plants, medicinal plants, and rare/endangered/endemic plants. Populus plant species was the most popular in research, showing 62 articles; and Castanea crenata 36; Pinus koraiensis 35; Robinia pseudoacacia 20; Ginko biloba 17, etc. Based on the survey and analysis, the following points are suggested: 1) improved evaluation of forest plants as non-wood resources, 2) expanding research topics on the basis of production, management, and utilization of non-wood forest resources, 3) management of database of forest plant information and encouragement needed to strengthen cooperative researches satisfying the needs of other industrial and scientific areas, and 4) encouraging to promote traditional knowledge based research on forest plants.

Many studies have been widely carried out to find out new compound having anti-cancer activity from animals and plants. Some plants have been reported to have anti-lancer effects. However, the anti-cancer effect of edible plants were seldomly evaluated. Therefore we investigated the anticancer effects of edible plants (10 samples) easily available around us by measuring number of survival cancer cells after treatment with direct cell counting and MTT analysis, and by examining the morphological change under the electromicroscope. Of the 10 samples tested, Equisetum arvense L., Lactuca dentata Mokino. var. faviflora Makino. showed moderate anti-cancer effects even at the concentration of 10 $\mul/ml$ against MCF-7 adenocarcinoma cell line. Of them, Capsicum annuum L. had most potent anti-cancer activity against MCF-7 adenocarcinoma cell line showing proliferation inhibited, morphological change and apoptosis at the concentration of 2 $\mul/ml$.

This study was conducted to elucidate the distribution of vascular plants and their value of Mt. Samyeong. The vascular plants that were collected 10 times from October 2013 to July 2015 consisted of a total of 538 taxa; 92 families, 308genera, 466 species, 3 subspecies, 62 varieties and 7 forms. The observed rare plant species as designated by Korea Forest Service were 24 taxa. Endemic species were 25 taxa. 28 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.3% and 8.7%. Among the surveyed 538 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 220 taxa, 195 taxa, 167 taxa, 65 taxa, 25 taxa, 8 taxa, 6 taxa and 3taxa, respectively.

Mt. Seoun(574 meters above sea level) is located in the southern part of An-sung city, Korea, within 36$^{\circ}$54'~36$^{\circ}$50'N, 127$^{\circ}$16'~127$^{\circ}$19'E. Field surveys were carried out nine times from March to October, 2000. Main results obtained from this study were as follows. The flora of vascular plants investigated in this survey was 439 taxa belonging to 90 families, 268 genera, 383 species, 49 varieties, 5 forma, 2 hybrid. As a result of this study, rare and endangered(Tricyrtis dilatata Nakai, Gastrodia elata Bl., Saururus chinenses Baill., Viola albida Palibin.) and many endemic species(Athyrium acatipinnulum Kodama., Tricyrtis dilatate Nakai, Paulownia coreana Uyeki., Salix hallaisanensis Lev., Asperula Iasiantha Nakai, Weigela subsessilis L.H. Bailey, Melamdryum seoulense Nakai, Clematis trichotoma Nakai, Spiraea prunifolia var. simpliciflora Nakai, Syringa dilatata Nakai, Chloranthus japonicus var. koreanus Sieb, Scutellaria insignis Nakai) of Korea were distributed in this area. Also the naturalized plants which were appeared in this area were 24 taxa(5.5 %). Among the plant resources, there are 239 taxa of edible plants(54.4%), 270 taxa of medicinal plants(61.5%), 217 taxa of ornamental plants(49.4%), 46 taxa of timber plants(10.5%) and 56 taxa of pasture plants(12.8%).

The anti-inflammatory and analgesic actions of Cedrela sinensis, Oenanthe javanica and ARtemisia princeps var. orientalis were carried out. The methanolic extract of Artemisia princeps var. orientalis showed the inhibitory effect on carrageenin-induced edema as well as vascular permeability in mice. And we also found the alagesic activity in these plants.
