This study was carried to establish a simple isolation and purification method of ginsenoside $F_1$ from leaves of Panax ginseng and was to evaluate the inhibitory effect of purified ginsenoside $F_1$ on the activities of elastase and tyrosinase. The content of ginsenoside $F_1$ was 90-fold higher in leaves than in root of ginseng. Ginsenoside $F_1$ was isolated from EtOAc fraction between EtOAc and alkalized water of 80% EtOH extract after remove of hydrophobic components. The 50% inhibitory concentration ($IC_{50}$) of ginsenoside $F_1$ on elastase activity and tyrosinase activity was 1.07 mM and 1.81 mM, respectively. Especially, inhibitory effect of ginsenoside $F_1$ on tyrosinase activity was higher than that of arbutin ($IC_{50}$; 2.20 mM). These results indicate that ginsenoside $F_1$ have a potential for industrial cosmetic materials.

The antioxidant activity of white ginseng was not recorded in Korea Functional Food Code, while its activity of red ginsengs was recorded. The aim of this study was to evaluate the antioxidant and hepato protective effect of different ginsengs in H₂O₂-treated HepG2 cells. White and red ginseng were prepared from longitudinal section of the same fresh ginseng (4-year old). The whole parts of white and red ginsengs were separately extracted with 70% ethanol and distilled water respectively, at 70 ℃ to obtain therapeutic ginseng extracts namely, WDH (distilled water extract of white ginseng), WEH (70% ethanol extract of white ginseng), RDH (distilled water extract of red ginseng) and REH (70% ethanol extract of red ginseng). In this work, we have investigated the DPPH, hydroxyl radical, Fe²⁺-chelating activity, intracellular ROS scavenging capacity and lipid peroxidation of different ginsengs. All these extracts showed a dose dependent free-radical scavenging capacity and a ROS generation as well as lipid peroxidation was significantly reduced by treatment with bioactive extracts of white ginsengs (WDH) than red ginsengs. Additionally, white ginseng extracts (WDH) has dramatically increased intracellular antioxidant enzyme activities like superoxide dismutase and catalase in H₂O₂-treated HepG2 cells. All these results explain that administration of white ginseng is useful as herbal medicine than red ginseng for chemoprevention of liver damage.

Metabolomics is the systematic identification and quantification of all metabolites in an organism or biological sample. NMR has been used as a major application tool in plant metabolomics such as quality control, chemotaxonomy, and analysis of genetically modified plants. Herbal medicines are the important therapeutics and are used to manage common diseases such as cold, inflammation, pain, heart diseases, liver cirrhosis, diabetes and central nerve system diseases. Herb plants include various kinds of species such as geranium, mint, and thyme and so on and contain different kinds of metabolites. We performed NMR-based metabolomics study on the seven different species of herb plants using $^1H$ NMR experiments and OPLS-DA to understand the correlation between the classification of herb plants and their metabolite contents. This study showed clear metabolic discrimination among various herb plants. This metabolmics study found several diagnostic NMR signals which are able to be used as bio-markers for identification of the specific herb plants among various species. Clear metabolic discrimination of herb plants suggests three chemotaxonomic groups of herb species.

Objectives : This study was designed to investigate the effect of water extract from Paeonia Lactiflora Pasll. with medicinal herb on plasma lipid and glucose in rats fed high fat diet. Methods : Experimental groups were divided into control diet group(C), high fat diet group(HF), high fat diet and 5% water extracts from Paeonia Lactiflora Pasll. with medicinal herb group(HFE I), high fat diet and 10% water extract from Paeonia Lactiflora Pasll. with medicinal herb group(HFE II). Weight gain, food intake, food efficiency, plasma lipid concentration and glucose were determined for 10 weeks during high fat diet. Results : In this experiment, body weight and food efficiency were significantly increase in high fat diet. High fat diet group showed elevated levels of total cholesterol, LDL-cholesterol and free fatty acid. Consumption of 10% water extract Paeonia Lactiflora Pasll. with medicinal herb lowers level of total cholesterol, LDL-cholesterol and free fatty acid. But levels of plasma triglyceride, HDL-cholesterol and glucose did not affect by high fat diet and water extract Paeonia Lactiflora Pasll. with medicinal herb Conclusions : In these results, water extract Paeonia Lactiflora Pasll. with medicinal herb in high fat diet group decreased plasma total cholesterol, LDL-cholesterol and free fatty acid. Thus the Paeonia Lactiflora Pasll. with medicinal herb might be useful in the treatment of hyperlipemia.

Objectives : We present some opinions to reduce the risk of herb-drug interactions through scanning "About Herbs" of the Memorial Sloan Kettering Cancer Center Website. Methods : We searched the Memorial Sloan Kettering Cancer Center Website of About Herbs and investigated herb-drug interactions. Results : There are 237 herbs and 196 drugs on About Herbs. 81.1% of herbs have fewer than 2 interactions listed.: 86.3% of drugs fewer than 3 interactions. Especially, 13 herbs were reported to have interactions with inclusive chemoagents on About Herbs. Only L-theanine has positive interaction with inclusive chemoagents. The others have negative interactions with inclusive chemoagents. 12 single chemoagents were reported to have interactions with some herbs. Especially tamoxifen-black cohosh, methotrexate-glutamin and aldesleukin-Huang Chi have positive interactions to increase the effects of the chemoagent. Conclusions : We should urgently create a risk management system of herb-drug interactions and take note of the risk of herb-drug interactions. We should build up systemic, evidence-based informations on popular herbs used by Korean cancer patients and herb-drug interactions in oncology like About Herbs.

This study examined the dyeability of fabrics dyed with rosemary, mint, sage, and thyme herb extracts. The herb extracts were pulverized and characterized by UV and FT-IR analysis. Dyeing properties of herb colorants on cotton, silk and wool fiber and effect of dyeing conditions on dye uptake were compared. The constituents of four different herbs were shown to be similar to each other. The dye uptake of rosemary and sage were shown to be larger than those of mint and thyme regardless of the fiber types. Affinity of herb colorants to protain fibers was higher than to cellulose fiber. Compared with silk and wool, the dyeability of cotton was the worse, the dye uptake of silk and wool fibers were increased along with dyeing time and dyeing temperature. As the dye uptake increased with increasing of the dye concentration, and its isothermal adsorption curves were langmuir type, indicating that ionic bonding was involved in the adsorption of herb colorants to the fibers.

A feeding trial was carried out to Investigate the effect of lipid level and herb mixture in the diets on growth of juvenile parrot fish, Oplegnathus fasciatus. Two plicate groups of fish averaging 4.5 g were fed four experimental diets containing herb mixture (0 and 5 g/kg diet) at each of two lipid levels $(8\%\;and\;16\%)$ for 8 months from summer to spring (water temperature, $7.2-25.4^{\circ}C)$. Weight gain improved with increasing dietary lipid level or supplementation of herb mixture during the first 4 months feeding period. Weight gain of fish fed the diet containing $16\%$ lipid level was significantly higher (P<0.05) than that of fish fed the diet containing $8\%$ lipid level. Weight gain of fish fed the diet with herb mixture was significantly higher (P<0.05) than that of fish fed the diet without herb at the $16\%$ lipid level. Feed efficiency was influenced by dietary lipid level or herb mixture during the first 4 months. On the other hand, weight gain and feed efficiency were not affected by dietary lipid level and herb mixture after 4 months until end of feeing period. Survival of fish fed the diet containing $8\%$ lipid without supplementation of herb mixture was the lowest among the groups (P<0.05). Lipid contents of liver and viscera tended to increase with increasing dietary lipid level during the first 4 months feeding period, however muscle lipid content was not influenced by dietary lipid and herb. Total cholesterol of serum was influenced by dietary lipid level during the first 4 months feeding period. These results indicate that an increase of dietary lipid level from $8\%\;to\;16\%$ and supplementation of herb mixture can improve growth performance of juvenile parrot fish when water temperature is optimum for growth such as the summer season in Korea.
