  • Moisture and quantum were measured to investigated out the growth characteristics of Adenocaulon himalaicum which is one of the important plants at the forest plants. The herbal medicines of Adenocaulon himalaicum known as one of the main mountain edible herbs have great value of resources according to the report that dopamine causing schizophrenia is greatly reduced with it. The moisture is a primary factor for the growth of Adenocaulon himalaicum. In this study we showed that the site with little change of temperature and under $200\;{\mu}mol\;s^{-1}m^{-2}$ quantum is suitable. Also, the maintenance of relative humidity over $50\%$ is a very important factor in the proliferation of shady spot plants.

  • The effects of MeOH extracts of ninety kinds of medicinal herbs on dopamine content in PC12 cells were investigated. Among them, the MeOH extracts at a concentration of $40\;{\mu}g/ml$ of Symplocarpus renifolius, Adenocaulon himalaicum and Mosla punctulata decreased $38.5{\sim}60.0%$ of dopamine content. Tyrosine hydroxylase, the rate-limiting enzyme of the catecholamine biosynthesis, was inhibited by the treatment of the MeOH extracts of Symplocarpus renifolius, Adenocaulon himalaicum and Mosla punctulata ($19.9{\sim}31.3%$ inhibition at $40\;{\mu}g/ml$). These results suggested that these bioactive herbal medicines exhibited partially an inhibitory effect on dopamine biosynthesis by the reduction of tyrosine hydroxylase activity in PC12 cells.

  • This study was performed to obtain basic data about vegetation structure and site environment of rare and endangered plant, viola websteri in five natural habitats. The dominant species of Hongcheon habitat were Pyrus pyrifolia (tree layer), Morus bombycis (subtree layer), Pyrus pyrifolia (shrub layer) and Isodon inflexus (herb layer). Mt. Yeonin habitat were dominated by Quercus mongolica (tree layer), Morus bombycis (subtree layer), Philadelphus schrenckii (shrub layer) and Viola websteri (herb layer). Mt. Yumyung habitat were dominated by Cornus controversa (tree layer), Morus bombycis (subtree layer), Fraxinus rhynchophylla (shrub layer) and Adenocaulon himalaicum (herb layer). Mt. Daebu habitat were dominated by Acer mono (tree layer), Staphylea bumalda (subtree layer), Staphylea bumalda(shrub layer) and Dryopteris crassirhizoma (herb layer). And the dominant species of Mt. Worak habitat were Larix leptolepis (tree layer), Fraxinus rhynchophylla (subtree layer), Alangium platanifolium var. macrophylum (shrub layer) and Adenocaulon himalaicum (herb layer). It was found out that the average acidity of soil pH was 5.23; 0.30ds/m for electron conductivity; 12.6% for organic matter content; 0.68% for total nitrogen; 21.66 ppm for available phosphorous; and 23.45 cmol(+)/kg for CEC. Interchangeable cation was decreased in order of $Ca^{2+}$ > $Mg^{2+}$ > $K^{2+}$. Viola websteri had positive association with Polygonatum odoratum var. pluriflorum and Geranium thunbergii but negative association with Poa sphondylodes. Species diversity index(H'), maximum Species diversity index (H' max), evenness(J') and dominance (1-J'), of investigated sites ranged 0.6816 (Mt. Worak)~0.9656 (Mt. Daebu), 1.0000 (Mt. Yeonin)~1.3010 (Hongcheon, Gangwon), 0.5330 (Mt. Worak)~0.8947 (Mt. Daebu) and 0.1053 (Mt. Daebu)~0.4670 (Mt. Worak) in woody layer and 1.0414 (Mt. Yumyung)~1.3295 (Mt. Worak), 1.4314 (Mt. Yumyung)~1.6435 (Mt. Daebu), 0.6984 (Hongcheon, Gangwon)~0.8356 (Mt. Worak) and 0.1644 (Mt. Worak)~0.3016 (Hongcheon, Gangwon) in herb layer, respectively.
