Seven native and four introduced herbs namely $Thymus$ $quinquecostatus$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Rosmarinus$ $officinalis$, etc. were selected for analysis of the DPPH radical scavenging and anti-microbial activity of their extracts. These perennial herbs are classified as $Labiatae$ and $Compositae$ except for $Saururus$ $chinensis$ and can be propagated through seedling and cuttage. These edible herbs are used as medicinal as well as ornamental plants. Their extract has electron donating ability which ranges from 69.7 to 78.7% for native herbs and 67.4 to 75.4% for introduced herbs. Native herbs have higher (3.54%) average DPPH radical scavenging than introduced herbs. In native herbs, maximum DPPH radical scavenging activity was observed in $Agastache$ $rugosa$ (78.7%) followed by $Saururus$ $chinensis$ while $Chamaemelum$ $nobile$ showed highest activity among the introduced herbs. Many herbs viz. $Saururus$ $chinensis$, $Chrysanthemum$ $zawadskii$ var. $latilobum$ and $Solidago$ $virga-aurea$ var. $gigantean$ showed excellent anti-microbial activity against gram positive $Enterococcus$ $faecalis$, maximum (80.0%) by $Saururus$ $chinensis$. Other herbs viz. $Solidago$ $virga-aurea$ var. $gigantea$, $Chrysanthemum$ $zawadskii$ var. $latilobum$, $Salvia$Salvia $plebeia$, $Chrysanthemum$ $indicum$, $Rosmarinus$ $officinalis$, $Chamaemelum$ $nobile$ and $Lavandula$ $stoechas$ showed anti-microbial activity against gram negative $Citrobacter$ $freundii$. Especially, the inhibition of colony growth of $Citrobacter$ $freundii$ was highest in the extract of $Chrysanthemum$ $zawadskii$ var. $latilobum$, and $Chamaemelum$ $nobile$.

Objective : This study was designed to evaluate candidate materials as anti-inflammation agent from extracts of various Korean Compositae herbs in Hwaak mountain. Among Korea medicinal herbs, Ainsliaea acerifolia (AA) belongs to the Compositae family, has been used for the treatment of rheumatic arthritis. However, AA has not been previously reported to have an anti-inflammatory effect. Therefore, we investigated the anti-inflammatory effects of AA and its underlying molecular mechanisms in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Methods : Cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in RAW 264.7 macrophages. Nitric oxide (NO) was measured with Griess reagent and pro-inflammatory cytokines were detected by enzyme immunoassay (EIA) kits in LPS-stimulated RAW 264.7 macrophages. Protein expressions of inducible nitric oxide synthase, and cyclooxygenase-2 (COX-2) and p65 subunit of nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) were determined by Western blot analysis. Results : Among 8 extracts of Korean Compositae herbs tested, AA showed the inhibition of NO production without cytotoxicity. Consistent with the observation, AA reduced the expression levels of iNOS and COX-2 proteins in LPS-simulated RAW 264.7 macrophages in dose-dependent manner. In addition, AA inhibited the productions of $TNF-{\alpha}$ and IL-6 in LPS-simulated RAW 264.7 macrophages. However, AA did not inhibit activation of p65 $NF-{\kappa}B$ in LPS-simulated RAW 264.7 macrophages. Conclusion : These results suggest that down-regulation of iNOS, COX-2 protein expression and $TNF-{\alpha}$ and IL-6 production by AA are responsible for its anti-inflammatory effects.

The antioxidative activity was measured on the substances of water and ethanol soluble extract from Astragalus membranaceus Bunge, Chrysanthemum morifolium Ramat, Lycium chinensis Miller, Glycyrrhiza uralensis Fischer, Angelica gigas Nakai, Zizyphus jojoba Miller, Paeonia lactiflora Pallas, Cnidium officinale Makino by four different in vitro experimental models of DPPH (a,a'-diphenyl-$\beta$-picrylhydrazyl) method, superoxide dismutase like activity, thiocyanate method, and TBARS (thiobarbituric acid reactive substances) method. The Lycium chinensis Miller contained the highest amount of polyphenolic compounds. The electron donating ability of water extract from Glycyrrhiza uralensis Fischer and ethanol extract from Chrysanthemum were higher than those of the others. The superoxide dismutase-like activity of water extract from Astragalus membranaceus Bunge was the highest among those of all the others. The water extract from Zizyphus jujuba Miller showed the highest antioxidative activity determined by TBARS method. Compared to the control, the inducing period associated with the oxidation degree was delayed up to 8 days in both the water extract from Chrysanthemum, Lycium chinensis Miller, Glycyrrhiza uralensis Fischer, and Paeonia lactiflora Pallas and the in ethanol extract from Chrysanthemum and Glycyrrhiz uralensis Fischer. These results support that water and ethanol extracts from 8 kinds of medicinal herbs contain antioxidative compounds.

Phytochemical compounds of Ligusticum striatum Makino are used as traditional medicinal herbs in Asia. These compounds are reported to have pain relief and antioxidant activities in gynecological and brain diseases. In this study, we investigated the antioxidant effects of Ligusticum fermented ethanol extract from Lactobacillus plantarum BHN-LAB 129 isolated from Kimchi, a Korean traditional food. The total polyphenol and total flavonoid contents increased by about 116.2% and 281.0% respectively, in the fermented Ligusticum extract as compared with those in the nonfermented Ligusticum ethanol extract. Superoxide dismutase-like (SOD), DPPH radical scavenging, ABTS radical scavenging, and reducing power activities increased by around 139.9%, 199.6%, 301.0%, and 137.1%, respectively, in the fermented Ligusticum ethanol extract as compared with these parameters in the nonfermented Ligusticum ethanol extract, respectively. In conclusion, the fermented Ligusticum ethanol extract with L. plantarum BHN-LAB 129 was effective in increasing the antioxidant effects. The bioconversion process in this study points to the potential of using Ligusticum to produce phytochemical-enriched natural antioxidant agents with high added value. The findings may prove useful in the development of improved foods and cosmetic materials.

The ${\gamma}$-irradiated medicinal herbs were examined the genotoxicological safety to consider the possibility of application of the irradiation technology for hygienic purpose. The three medicinal herbs -Glycyrrhigae Radix, Aurantii nobilis Pericarpium and Bupleuri Radix- were irradiated with ${\gamma}$ -rays at the practical dosage of 10 kGy. The hot water extracts of the irradiated herbs were examined in two short-term in vitro tests: (1) Ames test in Salmonella typhimurium TA98 and TA100, (2) Micronucleus test in cultured Chinese hamster ovary(CHO) cells. In the Salmonella reversion assays both with and without metabolic activation, the number of revertant colonies was not increased with each extract from the irradiated herbs, compared with negative controls. No significant difference in formation of the colonies was observed between non-irradiated and 10 kGy-irradiated herbs. These results indicated that no mutagenicity of the irradiated herbs was detected. In the micronucleus tests in cultured CHO cells, the incidences of micronucleus were not increased with irradiated herbs, and no significant difference in the incidences was observed between non-irradiated and irradiated herbs. These results indicated that no cytogenetic toxicity of the irradiated herbs was detected. The results of the two in vitro tests suggest that the irradiated herbs do not show mutagenic effects and cytogenetic toxicity. Further tests of in vivo genotoxicity and chronic toxicity are needed to determine the safety of the herbs irradiated with ${\gamma}$ -rays at practical doses.

The purpose of this study was to investigate the effect of 3 types of medicinal herbs (Glycyrrhizae radix, Astragali radix and Dioscorea rhizoma) extracts on estrogen-like activities, proliferation and differentiation in osteoblast. Human breast cancer cell line MCF7 was transfected using an estrogen responsive luciferase reporter plasmid for measure the estrogen-like activity. Estrogen-like activities of extracts were in the range of 1.11~5.73 fold to that of negative control. The extract of G. radix showed the strongest estrogen-like activities. The estrogen-like activities of 50 and $500{\mu}g/ml$ extracts of G. radix were similar to that of $10^{-8}$ and $10^{-7}$ M standard solution ($17{\beta}-estradiol$), respectively. G. radix extract showed no cytotoxicity against osteoblast MC3T3-E1 cells at $1{\sim}1,000{\mu}g/ml$. The extract of A. radix showed no significant proliferation of osteoblast. However, the extract of G. radix and D. rhizome showed maximum 148% and 133% proliferation effects. The extract of G. radix also increased alkaline phosphatase activity and the maximum was 122% at $100{\mu}g/ml$ compared to that of control. The nodule formation by the method of the Alizarin red S staining increased compared to control. These results suggest that G. radix is able to perform the bone formation and prevent osteoporosis.

The anti-diabetic effects of water extracts (WE) from medicinal herbs on hepatic glucose-regulating enzymes, such as glucokinase (GCK), pyruvate dehydrogenase (PDH), acetyl-CoA carboxylase (ACC) and ${\alpha}$-glucosidase, were studied using the cytosol fraction in liver and mitochondia fraction in heart of a type II diabetic animal (GK rat, Goto-Kakizaki). The free radical scavenging activity of water extracts by DPPH method was also tested. We found that free radical scavenging activity was strong in Corni fructu (CF), Mokdan Bark (MDB), Chenhwabon (CHB) and Sanyack (SY), while that of Backbocreng (BBR), Shuckgihwang (SGH) and Taecsa (TS) was lower. For GCK activity in cytosol of liver, CF and CHB had a more effective activity than other extracts. PDH activity in mitochondria fraction of heart was higher in all of the extracts, expect for the TS extract, than in the control. ACC activity in cytosol fraction of liver was significantly higher in the CF, CHB, SGH, TS and SY extracts than in the control. CF, BBR and MDB led to a decrease in the ${\alpha}$-glucosidase activity. Therefore, these results suggest that all of the extracts may be used as functional material in the development as anti-diabetic functional food and medicine.
