The following study is the result of herbal teas puffed at different temperatures between $140{\sim}220^{\circ}C$. There was change of single breadth that some carbonization occurs according to rise of processing temperature and crude ash content rises relatively, and crude protein and crude fat content had hardly changed and moisture content decreased. The solid elution rate of the herbal teas appeared by 0.18~0.27% (w/w), it increased as puffing temperature rises. The reason for the increase in solid elution rates is due to the breakage of cross bridges between the raw materials in the herbal tea which are carbohydrates, proteins, lipids and etc. after treatments of physical changes rather than chemical ones. Benzopyrene content happened difference in B(${\alpha}$)P content according to processing temperature, raw material by 0.18~0.24 ppbs.

The inhibitory effect of Chung-Jang-Hwan (C-mix) consisted of Geranium nepalense subsp. thunbergii, Saururus chinensis, and Rubus coreanus were investigated in dextran sulfate sodium (DSS)-induced colitic mice by microarray analysis. Treatment with Cmix improved colitic symptoms, including colon shortening and myeloperoxidase activity. Treatment with DSS alone upregulated the expression levels of inflammation-related genes, including IL-$1\beta$, IL-6, CCL2, CCL4, CCL5, CCL7, CCL8, CCL24, CXCL1, CXCL2, CXCL5, CXCL9 and CXCL10, and other colitis-related genes such as COX-2, PAP, MMP family, S100a8, S100a9 and DEFA1 in mice. However, treatment with C-mix inhibited the expression levels of inflammation-associated genes induced by DSS. The increased expression levels of COX-2 and IL-$1\beta$, representative inflammatory genes, were confirmed by a quantitative realtime polymerase chain reaction analysis. These results indicate that C-mix may ameliorate colitis by the inhibitory regulation of inflammation-associated genes.

To assess the antioxidative activity of 12 medicinal plants on lipid peroxidation, twelves traditional medicinal plants extracted with 95% methanol were investigated the antioxidative activity using DPPH, thiocyanate acid method, and thiobarbituric acid (TBA) methods. Out of 12 medicinal plants extracted with methanol, the extraction yields of Sedum kamtschaticum was the highest values (49.46%) among them and Geranicum sibiricum, Saururus chinensis root (R), Agrimonia pilosa leaf (L), Agrimonia pilosa root was the lowest value (9.97%). Radical scavenging effect of the selected traditional medicinal plants extracted from different extract solution were examined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical method. Antioxidative activity of methanolic extracts was higher than those of ethanol and n-hexane extracts. Scavenging effects in Sedum kamtaschaticum (R) determined by DPPH radical showed the highest among the 12 plants. The antioxidative effects of the first four medicinal plants were similar to those of butylated hydroxyanisole (BHA), and butylated hydroxytoluene (BHT), but higher than that of tocopherol, which was used as a handled control. Antioxidative effects of each indicated concentration of the methanolic extracts on linoleic acid by thiocyanate method was the highest in Sedum kamtschaticum and followed by Geum japonicum and Agrimonia pilosa and their antioxidative effect were similar to those of BHA, and BHT, but higher than that of tocopherol. Antioxidative effects of the selected medicinal methanolic extract on linoleic acid by thiocyanate acid method were examined for 15 days. Peroxidation of control and tocopherol group occurred on days 5 and 9, respectively, but BHA, BHT, selected medicinal methanolic extract group did not occur until on day 15. Antioxidative effects of the selected medicinal methanolic extract on linoleic acid by TBA method were examined for 15 days. Antioxidative activity was similar to those obtained by thiocyanate acid method.

Background: The transcription factor signal transducer and activator of transcription 3 (Stat3)is constitutively activated in many human cancers. It promotes tumor cell proliferation,inhibits apoptosis, induces angiogenesis and metastasis, and suppresses antitumor hostimmune responses. Therefore, Stat3 has emerged as a promising molecular target for cancertherapies. In this study, we evaluated the Stat3-suppressive activity of 38 herbal medicinestraditionally used in Korea.Methods: Medicinal herb extracts in 70% ethanol were screened for their ability to suppressStat3 in the A549 human lung cancer cell line. A Stat3-responsive reporter assay system wasused to detect intracellular Stat3 activity in extract-treated cells, and Western blot analyseswere performed to measure the expression profiles of Stat3-regulated proteins.Results: Fifty percent of the 38 extracts possessed at least mild Stat3-suppressive activities(i.e., activity less than 75% of the vehicle control). Ethanol extracts of Bupleurum falcatumL., Taraxacum officinale Weber, Solanum nigrum L., Ulmus macrocarpa Hance, Euonymus alatusSieb., Artemisia capillaris Thunb., and Saururus chinensis (Lour.) Baill inhibited up to 75% of thevehicle control Stat3 activity level. A549 cells treated with these extracts also had reducedBcl-xL, Survivin, c-Myc, and Mcl-1 expression.Conclusion: Many medicinal herbs traditionally used in Korea contain Stat3 activity-suppressing substances. Because of the therapeutic impact of Stat3 inhibition, these resultscould be useful when developing novel cancer therapeutics from medicinal herbs.

As part of method for ecologically utilizing abandoned paddy, potential of the abandoned paddy as a target site for ex-situ conservation of 9 endangered species of different life form was confirmed by considering the nature of rice paddy. In order to create Dum-bung, a component of traditional Korean rice paddy, a part of the abandoned paddy was modified to change the water environment. The seeds, asexual reproductive and sexually reproductive individuals of each endangerd species were transplanted into the abandoned paddy to observe the survival rate and phenological response for 1 year, and then monitored for 2 years. As a result, Hydrophyte 4 taxa (Euryale ferox, Saururus chinensis, Dysophylla yatabeana, Menyanthes trifoliata), Geophyte taxa 1 (Epilobium hirsutum), and Hemicryptophyte taxa 1 (Cicuta virosa) could be introduced into the abandoned paddy. In particular, Euryale ferox, Dysophylla yatabeana, and Menyanthes trifoliata should be introduced into Dum-bung, and Saururus chinensis, Epilobium hirsutum, and Cicuta virosa should be introduced into paddy wetland. Growth of Euryale ferox and Brasenia schreberi was inhibited by herbaceous species, and the growth of Epilobium hirsutum was inhibited by herbivores. Therefore, in order to help efficient settlement of endangered plants introduced in abandoned paddy, it is necessary to remove herbs that inhibit growth and to manage herbivores. In addition, it is necessary to prevent the collapse of paddy bank by planting on the paddy field trees or herbaceous forming vegetation mat. When using abandoned paddy ecologically, it is effective to diversify the moisture environment by creating a Dum-bung to increase biodiversity.

STAR of STAR (SS 01-04) is a series of drinks that consist of various extracts obtained from Coriolus versicolor, Artemisia capillaris Thunb., Hovenia dulcis, Acanthopanax sessiliflorus, Lycium chinense, Citrus reticulata, Saururus chinensis, Pueraria lobata, Pyrus pyrifolia, and Oenanthe javanica. A purpose of this study was to investigate the hepatoprotective effect of SS 01-04. Antioxidant activity of the drinks was evaluated by conducting a hydroxyl radical-scavenging assay. Cytotoxicity and hepatoprotective potential were determined using HepG2 cells in vitro, while protective effects against acute hepatotoxicity was evaluated in vivo. The antioxidant activity of the SS 01-04 at concentration of 100 and 250 mg/mL was similar to that of $50{\mu}M$ vitamin C. tert-Butyl hydroperoxide (tBHP)-induced production of reactive oxygen species (ROS) was blocked by SS 01, 03 and 04 in a dose-dependent manner. Treatment with SS 04 significantly lowered the serum levels of alanine aminotransferase and aspartate aminotransferase in an animal model of carbon tetrachloride $(CCl_4)-induced$ hepatotoxicity (p<0.05). In addition, SS04 increased glutathione level while decreased malondialdehyde level in the liver considerably (p<0.05). It also inhibited the $CCl_4-induced$ increase in the levels of triglyceride and cholesterol in serum and the liver. These findings indicated that SS 01-04 possessed antioxidant activity and protect against ROS. In particular, SS 04 is potentially highly beneficial in treating liver damage as it scavenges reactive free radicals and boosts the endogenous antioxidant system.

Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)-induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

The following is the study result of herbal tea roasted at different temperatures between $80{\sim}140^{\circ}C$. Depending on treatment temperature the water content decreased, some carbonization occurred and crude ash content relatively increased. Also crude protein and crude fat decreased little. Solid elution rate of herbal tea showed 0.15~0.32%(w/w) and the rate of solid elution decreased with higher roasting temperature. There was no big change in $80{\sim}110^{\circ}C$ treatment section but the solid elution decreased rapidly in $110{\sim}140^{\circ}C$ section. The reason for decreasing solid elution rate at higher treatment temperature is because the compact inner tissue makes elution difficult. Benzopyrene content (0.29~0.51ppb) showed a tendency to increase with higher treating temperature. From this result, the $B({\alpha})P$ content differed depending on the treatment temperature and raw materials. In case of roasting, the actual inside temperature is around $200^{\circ}C$ but since the surface temperature of the roaster reaches around $2000^{\circ}C$ some portion of $B({\alpha})P$ content was presumed to be produced from the area that came in contact with this surface. When the processing which is a main component of food carbohydrate, protein, fat reason despite serve heat treatment as a whole is to be detected even though the $B({\alpha})P$ in this way is considered to be.

Effects of medicinal herb extract on nonspecific immune responses, hematology and disease resistance against Edwardsiella tarda in olive flounder, Paralichthys olivaceus were evaluated. Wormwood, Artemisia asiatica NAKAI and barrenwort, Epimedium koreanum NAKAI were mixed at a ratio of 7 : 3 (w/w) for 2-herbs extract and wormwood, barrenwort, Korean forsythia, Forsythia koreana NAKAI, chrysanthemum, Chrysanthemum zawadskii var. latilobum KITAMURA, peppermint, Mentha arvensis L. var, piperascens MALINV., great burnet, Snaguisorba afficinalis L., Lizard tail. Saururus chinensis BAILL., mulberry, Morus alba L., and star anise, Illicium varum HOOK, f, at the same weight for 9-herbs extract. Two-herbs of 9-herbs extract were prepared by heating after adding 10㎖ of distilled water per g of the herb mixtures. Fish (10.3$\pm$2.5g) were fed the experimental diets supplemented with the 2-herbs or 9-herbs extract at the different concentrations of 0%, 0.1%, 0.5% and 1% per kg diet for 12 weeks. Lysozyme and bactericidal activities of serum, and hematological characteristics were examined during experimental period. After feeding test period, all experimental groups were challenged with E. tarda. Lysozyme activity from the fish fed the diet supplemented with 0.1% or 0.5% of 2-herbs extract was significantly higher than the control. But there was no difference both in bactericidal activity and hematology among each group. Sixty seven % of relative percent survival values (RPS) in the group fed the diet supplemented with 0.1% of 2-herbs was higher than the other group and the control. These results suggest that supplenmentation of 0.1% of 2-herbs extract to a commercial diet may enhance disease resistance in olive flounder. Although both 0.1% and 0.5% 9-herbs extract did not improve non-specific immune reponses, they could enhance disease resistance of 53% RPS, respectively.

The purpose of this study was to investigate total polyphenols, total flavonoid, and DPPH radical scavenging activity in 26 species of Korean natural plants and 14 species of medicinal plant extracts. The plant containing the highest total polyphenols and total flavonoids were Plantago asiatica, and Lespedeza cuneata G. Don, respectively. The content of polyphenols and flavonoids in natural plants was the highest in Lespedeza cuneata G. Don, which also demonstrated high DPPH radical scavenging activity. In medicinal plant extract, Saururus chinensis (Lour.) Baill and Artemisiae Asiaticae Herba had the highest level of total polyphenols (194.60 and 203.92 mg/g extract, respectively) and DPPH radical scavenging activity. Diospyros kaki Thunb and Dryopteris crassirhizoma did not contain high levels of total polyphenols (112.98, 121.46 mg/g extract, respectively) and flavonoids (46.10, 58.69 mg/g extract respectively), but DPPH radical scavenging activity was relatively high. Further study regarding plants that exhibit higher total polyphenols, total flavonoid, and DPPH radical scavenging activity is needed.
