  • This study was to describe the ecological survey of wetland plants from Sinbul Mt. and suggest the ways of the sustainable ecological management and wise use. We found 167 plant species. Molinia japonica HACK was the most dominant species and Asarum maculatum NAKAI, Drosera rotundifolia L. and Utricularia racemosa WALL were considered as the most important species. Thus, it was concluded that this area need strong conservation due to the necessity for species diversity. Such several management schemes as the designation for national wetland conservation area, continuous monitoring, cautious surveillance and wise management were suggested to implement successful conservation.

  • To investigate bioactive materials for development of natural conservative agent on organic cultural heritage, methanol extracts from 17 medicinal plants were screened for antifungal and insecticidal activity against 6 wood rot fungi and adult of Lasioderma serricorne. Antifungal activity of extracts was tested by using paper disc soaking method against wood-rot fungi. Among these extracts, the most significant antimicrobial activity was observed from the extract of Coptis japonica at 5 mg/disc against all wood rot fungi tested. The insecticidal activity of extracts was examined by topical application against L. serricorne adults. The extracts from Asarum sieboldii gave 83.3 % mortality at $25{\mu}g/adult$ for 24hr. From these result, the methanol extract from C. japonica and A. sieboldii described could be useful for conservation of organic cultural heritage against biological deterioration by wood rot fungi and L. serricorne.

  • To develope new natural substances for whitening agent, Baeckji(Angelica dahuria;BK), Seasin(Asarum sieboldii;SS). Baecjgangjam(Bombycis corpus;BGJ) and Mynkanbang(MKB) were selected and extracted by hot water and 70% EtOH, respectively. Hydrothermal and ethanolic extracts of BK, SS, BGJ and MKB were evaluated for anti-oxidative effect, tyrosinase activity, melanogenesis of B16 melanoma cells and changes in level of tyrosinase expression by using Western blotting. All hydrothermal and ethanolic extracts showed scavenging activities of free radicals against 1,1-diphenyl-2-picrylhydrazyl(DPPH) but no inhibitory effect on tyrosinase activity. Ethanolic extracts of BK, SS, and BGJ and especially highly, those of MKB inhibited production of melanin in B16 melanoma cells and were able to reduce the level of tyrosinase expression in B16 melanoma cells. These results suggest that ethanolic extracts of BK, SS, BGJ and MKB can be an effective whitening agent from natural plant.

Based on the list of the rare plants by the Forest Research Institute, 3 taxa and based on the list of Korean endemic plant 4 taxa were recorded in the studied areas; Puccinellia coreensis (Gramineae), Asarum maculatum (Aristolochiaceae), Prunus yedoensis (Rosaceae), Koelreuteria paniculata (Sapindaceae), Adenophora triphylla var. hirsuta (Campanulaceae). The Specific Plant Species which is categorized by the Ministry of Environment, Korea, was summarized as 23 taxa for the 1 degree of 17 taxa, 3 degree of 5 taxa, 5 degree of 1 taxa in Jangsoo-ri windbreak forest and 22 taxa for the 1 degree of 18 taxa, 3 degree of 3 taxa, 5 degree of 1 taxa in Pyeongsa-ri windbreak forest. From the enlisted the flora surveyed, the naturalized plants were 17 taxa in Jangsoo-ri windbreak forest and 19 taxa in Pyeongsa-ri windbreak forests with the Naturalization rate was 8.7 percent and 12.6 percent, respectively. In Jangsoo-ri windbreak forest, there has been occurred many man-made impair and development without legal institution and control. So, it needs in haste institutional conservation measures and systemic database construction about function and necessity of windbreak forest. In Pyeongsa-ri windbreak forest, recently many people visited here. So, if we make eco-tour place connecting nearby coast and windbreak forest, it will contribute resident's economic profit and opportunity, concerns about windbreak forest, and necessity of conservation measures. Recently, the windbreak forests in Jangsoo-ri and Pyeongsa-ri should be bereaved windbreak forest of function by the human activities.

  • Objectives: Asari Herba comes from the dried perennial herbaceous plant, Asarum sieboldii $M_{IQ}$., A. heterotropides $F_R$. SCHMIDT var. mandshuricum($M_{AXIM}$) $K_{ITAG}$. and A sieboldii $M_{IQ}$ var. seoulense $N_{AKAI}$., family Aristolochiaceae. This medicine is pungent in flavor(味辛), warm in nature(性溫), mildly toxic and affects the lung, kidney, and heart meridians. It is able to repel wind dispel cold(祛風散寒), remove the obstruction of the nose(宣通鼻竅), relieve pain(止痛) and warm the lungs to remove the retention of fluids(溫肺化飮). In a clinic it is prescribed for exterior syndrome of wine-cold type(風寒表證) manifested as headache and general pain. It is indicated for headaches, toothaches, bisyndrome of wind-cold-dampness type(風寒濕痺), etc. For many generations medical books have warned doctors that the dosage of Asari Herba should not be excessive because the pungent flavor has the effect of dispersing exopathogens from superficies of the body. The principle, 'Asari Herba should not exceed Jeon(錢, Qian, 3.0 gram)' is still considered to be relevant. Methods : Extensive research of several ancient medical texts has lead to the following conclusion. Results : The statement 'Asari Herba should not exceed Jeon' is a dosage which is used to prepare single recipe and powder. Conclusion : The definition of Jeon is not 1 Jeon(3.0 gram), but 1 Jeonbi(錢匕, Qianbi, 1.0 gram), moreover, the usage, collection. and refinement process are not in accordance with the contents of the ancient medical texts. A deeper study of Asari Herba's dosage in the future is expected to have interesting results.

  • This experiment was conducted to investigate the change of root yield and essential oil contents by cultivated year in Asaram siebold Mio. Growth of aerial part such as plant height, leaf length and leaf width increased rapidly in two to three-year-old. Root length and root weight per plant were increased as cultivation year passed. Especially the speed of development was very fast in two and three-year-old alike aerial part. Root yield was the highest at five-year-old. The content of essential oil was decreased gradually as cultivation year passed. Methyleugenol content was increased, while safrole content was decreased by cultivated years. The increasing of methyleugenol content in four to five-year-old was not higher than three to four-year-old. In the result, it concluded that the optimum harvest time of Asarum sieboldi MiO is five-year-old cultivated based on root yield and effective medical components.
