  • Recent studies suggest that activated microglial cells play an essential role in the inflammatory responses and neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease. This study was conducted to evaluate the protective mechanisms of Asiasarum sieboldi (AS) on LPS-induced activation of BV-2 microglial cells. The effects of AS on gene expression profiles in activated BV-2 microglial cells were evaluated using microarray analysis. BV-2 microglial cells were cultured in a 100 mm dish ($1{\times}10^7$/mL) for 24 h and then pretreated with 1 ${\mu}g$/mL AS or left untreated for 30 min. Next, 1 ${\mu}g$/mL LPS was added to the samples and the cells were reincubated at $37^{\circ}C$ for 30 min and 1 hr. The gene expression profiles of the BV-2 microglial cells varied depending on the AS. The microarray analysis revealed that MAPK signaling pathway-related genes were downregulated in AS-treated BV-2 microglial cells. AS can affect the neuroinflammatory-related pathway such as MAPK signaling pathway in activated BV-2 microglial cells.

  • Treatment of ethylacetate extract of Asiasarum sieboldi inhibited the germination and the growth of radish seeds. Two phenylpropanoids were isolated from ethylacetate extract. Their structures were identified as safrole and o-methyleugenol by spectroscopic evidence. From the test to inhibitory effect, o-methyleugenol had inhibited the germination and the growth of radish seeds, while safrole did not. The germination rate and radicle length of radish seeds were decreased to 63.0%, 31.5 % of control at 5mg/ml of o-methyleugenol, respectively. At the same concentration, o-methyleugenol inhibited the hypocotyl growth up to 100%.

  • To explain the theory of KIMI which is the theory of therapeutics in oriental medicine, monoamine oxidase(MAO) activities were measured in the brain and liver of mice which were orally administered oriental medicinal herbs which were classified into cold and hot drugs. Rheum palmatum, Anemarrhena asphodeloides, Gardenia jasminoides, Scutellaria baicalensis and Coptis japonica were considered as the cold drugs and Zingiber officinale, Aconitum carmichaeli, Asiasarum sieboldi, Evodia officinalis and Cinnamomum cassia were included in the hot drugs. The effects of cold and hot drugs on in vitro enzyme activities were measured and compared with the in vivo effects. Serotonin is important neurotransmetter involved in the control of body temperature. The MAO plays a central role in the metabolism of many neurotransmetter monoamines including serotonin. MAO is a flavoprotein found exclusively in the mitochondrial outer membrane, occuring in the MAO-A and MAO-B subtypes. MAO-A deaminates serotonin and noradrenaline, whereas MAO-B prefers phenylethylamine and benzylamine as substrates. Coptis japonica and Aconitum carmichaeli elevated the in vivo MAO activities and especialy, in vivo MAO-B activities were significantly increased. In vitro MAO-A activities were increased by hot drugs, whereas the in vitro MAO-B activities were inhibited. Cold drugs inhibited both enzyme activities in vitro.

  • In this study, the extracted phenolic compounds from 98 species of oriental herbal medicine were examined for biological activities to be used as functional resources. In particular, the anti-gout effect by xanthine oxidase (XOase) inhibition was determined using water and ethanol as extraction solvents because of their non-toxicity in the human body. The extracts of Chrysanthemum indicum L. (83.45%), Cuscuta chinensis (60.22%), Asiasarum sieboldi F. Maekawa (51.66%), Acorus gramineus (67.8%), Aconitum pseudo-laeve var. erectum (75.23%), Thuja orientalis (47.27%), Polygonum aviculare (53.98%), Carthami semen (63.99%), and Syzygium aromaticum (40.22%) showed relatively high XOase inhibitory activity. Chrysanthemum indicum L. was selected for its high XOase inhibitory activity. The biological compounds in Chrysanthemum indicum L. were identified to contain phenolics included in extracts of solids. Ultra-fine grind technology showed a higher extraction yield than normal grind and fine grind technology. Ethanol extracts showed relatively higher XOase inhibitory activity than water extracts. XOase inhibitory activity increased in a dependent manner as phenolic concentration increased. Therefore, ultra-fine grind technology was confirmed for use in increasing the extraction yield of XOase inhibitory compounds from Chrysanthemum indicum L.. Extracts from Chrysanthemum indicum L. are expected to be a useful functional resource for the prevention or treatment of gout.

  • Brown patch (Rhizoctonia solani AG1-1), dollar spot (Sclerotinia homoeocarpa), pythium blight (Pythium spp.), anthracnose (Colletotrichum graminicola), yellow patch (Rhizoctonia cerealis) and Zoysia patch (Rhizoctonia solani AG2-2) are the major turfgrasses diseases in Korea. In this study, 23 medicinal plant extracts were tested for antifungal activities against turfgrass pathogenic fungi. In paper disk diffusion method, 12 medicinal plant extracts, including Sophora flavescens, showed antifungal activity. Also, in the test of antifungal activity on media contained the extracts of S. flavescens, Curcuma longa, Rheum undulatum, Coptis chinensis and Asiasarum sieboldi showed above 80% inhibitory effects on the mycelial growth in 110 mg/10 ml concentration of the extracts. S. flavescens, in particularly, showed antifungal activity against the six turfgrass pathogenic fungi. The inhibition rate of S. homoeocarpa was 100% in 10 mg/10 ml, 5 mg/10 ml and 2 mg/10 ml concentrations of C. longa extract. In case of Pythium spp., the extracts of S. flavescens, R. undulatum and C. chinensis showed 100 % inhibition rate on the test media.

  • This is a part of the study on the food materials that are effective for diabetes treatment and for use in the development of functional bread products. In this study, various commercially available Oriental medicines with the intestinal absorption enzyme called ${\alpha}$-glucosidase, which is known to be effective for diabetes treatment, were explored. According to the research results on the water and methanol in 200 kinds of Oriental medicines, which were separated by layer to investigate the inhibitory activity of ${\alpha}$-glucosidase, Astragalus membranaceus (70.9%) in the water layer and Pericaeta communissima (72.9%) in the MeOH layer showed a strong inhibitory effect of over 70%. Myristica fragrans (69%), Morus alba (66.9%), Schisandra chinensis (65%), Panax notoginsens (63.9%), Anthriscus sylvestris (62.9%), Asparagus cochinchinensis (62.1%), Erycibe obtusifolia (60.9%), Polygonum cuspidatum (60.7%), Atractylodes lancea (60.2%), and Perilla frutescens (60.2%) in the water layer, and Codonopsis pilosula (67.8%), Prunus persica batsch (67.6%), Sinomenium acutum (63.5%), and Malvae semen (61.6%) in the MeOH layer, showed a more than 60% inhibitory effect. Thirty one species, including Polygonatum sibiricum (59.8%), Medicata fementata (59.7%), Alisma canaliculatum (59.5%), Coix lacryma-jobi (59.2%), Asiasarum sieboldi (59.0%), and Bupleurum falcatum (53.0%), in the water layer, and 10 species [Quisqualis indica (58.8%), Lycium chinense (58.3%), Trichosanthes kirilowii (58.0%), Thuja orientalis (55.9%), Bombyx mori (55.6%), Gallus domesticus (55.4%), Aralia continentalis (55.3%), Cibotium barometz (52.7%), Euphorbia pekinensis (52.7%), and Dolichos lablab (52.5%)] in the MeOHlayer, showed a more than 50% inhibitory effect. Therefore, such materials are expected to be the basic materials that will be used for the development of functional materials for diabetes treatment.
