The herb of Allium victorialis var. platyphyllum (Liliaceae) has been used as an edible wild herb and to treat heart failure and gastritis. We have already reported antihyperlipidemic anti-tumor effects of this plant. To enlarge the commercial availability of this food, it was investigated whether the extracts of A. victorialis var.platyphyllum reduce hyperlipidemia and obesity or not. The plants tested in this experiment were collected from two eco-types of IS. Ullung and Mt. Odae cultivated at Pyongchang. Extracts were prepared by extracting the fresh leaves and those dried at $36^{\circ}C$ and $90^{\circ}C$, respectively. Pretreatment with the ethanolic extracts for two weeks (p.o.) reduced serum triglyceride-, total cholesterol- and LDL-cholesterol contents in rats induced by Triton WR-1339, respectively. Furthermore, oral administration of the extracts also inhibited the hyperlipidemia induced with oral diet of 30% corn oil. In the other attempt to find to alleviate the obesity, the model rats with obesity were induced by the high fat-diet for six weeks. Post-treatment with the extracts for two weeks significantly reduced the hyperlipidemia. Retroperitoneal-, epidymal- and total abdominal fat pad weights were considerably reduced at 100 mg/kg oral administration of the extracts. Increased feces lipid contents were also found in the rat treated with the extracts. The extract of Mt. Odae eco-type showed more potent activity than that of Is. Ullung one. These results suggest that use of the fresh leaves may lead to the higher activity in treatment of hyperlipidemia and obesity than of the dried one.

Cosmetics are products used over long periods by the public, and their safety is very important. Contact dermatitis induced by cosmetics is the result of an inflammatory response of the skin to direct irritancy. The initial event that this inflammatory response is observed is the release of pro-inflammatory cytokines. In this study, the anti-inflammatory activities of extracts from Korean herb medicines were investigated using RAW264.7 macrophage. Among the fifty one extracts tested, the ethanol extracts from Biotae Orientalis Folium, Biotae Orientalis Folium (roasted), Cyperi Rhizoma, Nepetae Spica, Benincasae Semen, Dioscoreae Rhizoma, Dioscoreae Rhizoma (roasted), Mori Ramulus, Pini Ramulus and Alismatis Rhizoma reduced the cytotoxicity and inhibited the productions of Nitric oxide (NO) and cytokines such as interleukin (IL)-1${\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$n lipopolysaccharide (LPS)-induced RAW264.7 macrophage. Additionally, they didn't induce the skin irritation when tested the human patch test. Overall, the result of this study suggests that the extracts of the ten Korean herb medicines are useful cosmetic agents for preventing the skin irritation.

Objective : In order to find antiviral compounds against Herpes simplex virus type I(HSV-1) and II(HSV-2) from herb medicines, a convenient virus-induced cytopathic effect(CPE) inhibition assay was introduced. Methods : Fourteen purchased herbal medicines, and their toxicity of infected cell and anti-viral activities were evaluated. Among them, the major part of herbal medicines showed cell stability compared with the contrast. Results : Cytotoxic concentration (CC) of the $H_2O$ extracts of Hyongbangpaedoksan against HSV-1 and HSV-2 was 181.12. This is high level cytotoxic concentration compared with the contrast. Therefore, we assumed that the high level cytotoxic concentration of herbal medicine play a major role in improvement of antiviral activity at the first infective cell. But antiviral effect was unable to figure out for selective index(Sl)=CC50/EC50. The other herbal medicines were unable to showed potent anti-HSV activity. Conclusions : The antiviral activation using herbs in this thesis have unlimited objects, to select research object will help to show the direction of antiviral drug development that have less side effect and more excellent efficiency.

To maintain the quality characteristics of vegetables, produce was dipped in Korean medical herb extracts (KMHE) such as Rheum palmatum L. or Coptis chinensis Franch with different concentration. Dipping in 500 ppm KMHE solution was suitable for the reduction or microbial load on cucumber, and 100 ppm KMHE solution was appropriate for others. Dipping time was suitable for produce about 10 minutes, and the temperature of dining solution had a limited effect cm the microbial load reduction. Antimicrobial activity of Coptis chinensis Franch and Rheum palmatum L. was maintained for cucumber and zucchini wrapped with polyvinylchloride film during storage at 10$^{\circ}C$.

The three crude drugs of the Kalopanax pictus (Araliaceae) roots (K), Pueraria thunbergiana (Leguminosae) flowers (P), and the Rhus verniciflua (Anacardiaceae) heartwood(R) used for anti-thirst drugs in Oriental herb medicine were extracted with MeOH, respectively, and the successive fractionation of the extract gave EtOAc extract. Certain amount ratios of the three extracts were also prepared to compare the antimutagenicity in Ames test. In N-methyl-N(-nitro-N-nitrosoguanidine (MNNG; 0.4 (g/plate)-induced test, the activities of complex mixture were observed between the highest antimutagenic activity of K extract and the lowest P extract. In aflatoxin (AFB$_1$)-induced test, the EtOAc complex (K : P : R=l : 1 : 3) labeled E-113 decreased the revertants of Salmonella typhimurium TA100 by 95％, which activity were highest among other extracts or complexes mixture used. Fractionation of organic solvent mostly increased the antimutagenicity. These trends were also observed in the antimutagenicity test of the mixture of each active component of kalopanaxsaponin A, tectorigenin and sulfuretin. These results supported that many kinds of anti-thirst herb medicine in the prescription could effectively prevent cancer disease.

This study was conducted to determine whether Pleurotus ostreatus (oyster mushroom), cultivated in various ratios with herbal extract remnants instead of cotton supplemented with nutrients (the control), improved mycelial growth, mushroom yields and longevity during storage. In addition, we investigated the transfer of medicinal herb components into the mushrooms since they contained non-specific medicinal herbs and their composition could not be controlled. Mushrooms cultivated with 70% and 100% medicinal herb remnants had faster growth rates, higher yields and less failure in the development of the fruit body than the control group. There were no differences in HPLC chromatogram among the methanol extracts of Pleurotus ostreatus in all groups. In addition, glycyrrhizin, an indicative compound of licorice which was a major herb among the herbal remnants, was not detected in any of the extracts. Pleurotus ostreatus that was cultivated with 70% and 100% herbal extract remnants had improved storage longevity in comparison with the control. They exhibited the least weight loss during storage among the groups and they maintained firmness in the stipe and pileus. However, the sources of media did not alter the color difference of the stipe and pileus or the quality index of the outward appearance during storage. In conclusion, cultivating media that contained over 70% of medicinal herb extract remnants increased the growth rates and yields of Pleurotus ostreatus. In addition, these mushrooms had enhanced storage longevity due to their firmness. Therefore, medicinal herb extract remnants should be utilized in the cultivating media of various mushrooms.

We prepared five different kinds of herb mixtures prescribed for hypoglycemic effect. And the physicochemical properties of their water extracts were assessed to identify functional materials. Yields were in the range $19.52{\sim}29.79%$. Total phenolics and flavonoid contents were $349.24{\sim}1,752.21\;mg%$ and $163.06{\sim}1,118.47\;mg%$, respectively, and herb mixtures No. 2, 3 and 5 showed particularly high levels greater than 1,000 mg%. Electron-donating ability was best in herb mixtures showing high levels of total phenolics and flavonoids. Nitrite-scavenging abilities were more than 70% in herb mixtures No. 2 and 5, and decreased as pH increased. Herb mixture extracts strongly inhibited differentiation of 3T3-L1 fibroblasts, with potencies ranked in the herb mixture order 5, 1, 4, 3, and 2. The five different kinds of herb mixtures prescribed for their hypoglycemic effects may be useful as functional food materials.
