This study was carried out to investigate the growth responses of medicinal plants such as Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata under 70%-shading and full sunlight conditions on a rooftop condition using artificial soil as a growth media. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth on plant height, leaf length, leaf width, petiole length and leaf number under full sunlight conditions on a rooftop condition. Cryptotaenia japonica and Houttuynia cordata had high value of Hunter's a (red-green) under full sunlight, while had lower value of L(lightness) and b(blue-yellow) than those of 70% shading condition. As an index of plant stress response, Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, Ligularia fischeri showed Fv/Fm values 0.79~0.84 under full sunlight in August, indicating low stress on plant growth. Therefore they seemed to be suitable medicinal plats for rooftop conditions. Ligularia fischeri and Reynoutria japonica showed better growth under 70% shading treatment in August, while showed high growth response under full sunlight conditions in September. The 70% shading treatment was effective for the growth of Angelica gigas, Reynoutria japonica, and Aralia cordata. Angelica gigas and Reynoutria japonica, however, showed better plant growth under full sunlight during summer. The results showed that Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordat seemed to be suitable medicinal plants for rooftop garden where there is a full sunlight condition.

To identify potential gastrointestinal prokinetic agents, water and 70% ethanol extracts and isolated compounds from 41 different traditional medicinal herbs were evaluated for the stimulation of gastrointestinal (GI) motility in vivo. Of the 41 water and 70% ethanol extracts, 12 extracts were found to enhance GI motility activity in mice by more than 10%. The 12 extracts are as follows: Atractylodes japonica (root), Crataegus pinnatifida (flower), Aucklandia lappa (root), Inula helenium (root), Cynanchum wilfordii (root), Chinese Liriope platyphylla (root), Codonopsis pilosula (root), Glehnia littoralis (root), Pinellia ternate (tuber), Agastache rugosa (aerial part), Angelica decursiva (whole plant), and Peucedanum praeruptorum (whole plant). In particular, the extracts from Atractylodes japonica (root), Cynanchum wilfordii (root) and Angelica decursiva (whole plant) have demonstrated the highest GI motility activity. In addition, 26 isolated compounds from the medicinal herbs were tested, and 8 isolated compounds were found to be active. They are ${\alpha}$-ionone, ${\beta}$-ionone, trans-caryophyllene, cedrol, methyl-3,5-di-O-E-caffeoyl-quinate, lobetyolin, oleoyllinoleoylolein and cis-jasmone. ${\beta}$-ionone from Aucklandia lappa (root) showed the most potent GI motility activity. The active traditional medicinal herbs and isolated compounds might be therapeutically advantageous in the treatment of GI motility disorders.

The objective of this study is screening the anti-oxidative effects of several plant MeOH extracts against oxidative stress in Neuroblastoma cell. Oxidative stress has been implicated in the pathogenesis of many neurotoxicity, neurodegenerative disorders and cell death. This oxidative stress is generated by ROS (Reactive Oxygen Species) such as nitric oxide, nitrogen dioxide, peroxyl, superoxide ($O_2^-$), hydroxyl, alkoxyl. So, in the present study, we induced oxidative stress by treatment of sodium nitroprusside (2.5 mM) in human neuroblastoma SH-SY5Y cell which was treated samples before 24hr, and cell viability was measured by MTT reduction assay. Of those tested, the extracts of Paeonia japonica (roots), Eucommia ulmoides (炒)(barks), Paeonia japonica (曝乾)(roots), Phyllostachys bambusoides (stems), Polygala tenuifolia (去心, 炒)(roots), Paeonia japonica (roots), Polygala tenuifolia (roots), Machilus thunbergii (barks), Mallotus japonicus (leaves), Poria cocos (whole), Sophora flavescens (roots), Angelica tenuissima (roots), Angelica gigas (當歸尾)(roots) showed anti-oxidative effects[$EC_{50}$<15.20 ${\mu}g$/ml(Carnosine:Positive control)]in dose dependent manner.

Irradiated and non-irradiated Korean medicinal herbs were extracted by water and 70% ethanol. Antimicrobial activity of these extracts were invesigated against selected food hygiene microoganisms. The ethanol extracts of the non-irradiated Agrimonia pilosa ledebour japonica Nakai, Curcuma longa Linne and Angelica gigas Nakai were completely inhibited on four species of bacteria, such as Vibrio parahaemolyticus, Clostridium perfringenes, Bacillus subtilis and Staphylococcus aureus. Also, above four strains did not have antibacterial activity in the water-ethanol mixtures. Futhermore, the ehtanol extracts of the non-irradiated Agimonia pilosa ledebour Japonica Nakai, Curcuma Iedoaria Roscoe, Curcuma longa Linne and Scutellaria baikalensis George were shown inhibitory effects against Aspergillus flavus and Pen icillium islandicum. And the water extract of Scutellaria baikalensis George was the same effect to these molds. Essentially the same results were observed when samples irradiated at a dose of 10 kGy.
