Antioxidant activity of Astragalus membranaceus, Polygonatum stenophyllum, Angelica gigas, Acanthopanax sessiliflorus and Angelica pubescens extracts cultivated in Jecheon prepared with different solvents were determined by 1,1-diphenyl-2-picrylhydrzyl(DPPH) radical scarvenging ability and thiocyanate method . The highest hydroxy radical scarvenging activity was shown in Acanthopanax sessiliflorus, while the lowest was in Polygonatum stenophyllum. Angelica gigas showed strong antioxidant activity by thiocyanate method. Methanol extracts and water extracts showed higher antioxidant activities than ethanol extracts. Angelica pubescens showed the highest polyphenol contents and Acanthopanax sessiliflorus showed the highest flavonoid contents. Direct correlation between the hydroxy radical scavenging activity and polyphenol contents or flavonoid contents was established by simple regression(r>0.8) in each solvent extracts. Among medicinal plants cultivated in Jecheon, Acanthopanax sessiliflorus and Angelica pubescens showed strong antioxidant activities. These results suggest that methanol or water extracts of several medicinal plant cultivated in Jecheon could be used as natural antioxidants.

Crataegi Fructus has often been cited in medical literature for its medicinal effects. The purpose of this study was to investigate the possibility of Crataegi Fructus application as an edible medicinal (nutritional supplement) food resource. In this study, Crataegi Fructus, which has been used in oriental medicine and folks remedy, was investigated to characteristics of nutritional composition(protein, lipid, ash, fiber, free sugar and minerals). The approximate composition of low Crataegi Fructus was crude protein, 0.26%, crude lipid, 0.30% and crude ash, 0.66%. And total dietary fiber 5.60%(insoluble 4.66%, soluble 0.94%), contents of glucose and fructose were 5.02mg% and 6.21 mg%, Nutritional composition of fermented liquid was crude protein 0.24%, crude lipid, 0.03%, crude ash, 0.53% and total dietary fiber, 0.24%. And glucose, fructose contents were 14.77mg% and 7.30mg%. The other hand, nutrition contents in water extract of Crataegi Fructus were significantly lower than low Crataegi fructus and fermented liquid. The above results showed that Crataegi Fructus and fermented liquid have sufficient values to use as a food stuff for medicinal food and nutritional supplement.

This study investigated the attitudes of dietitians regarding medicinal cuisine for school meal services. Data was obtained with self-administered questionnaires from 261 dietitians in schools located in Yeoungdong, Gangwon-do. Subjects were distributed into three groups (Elementary=116, Middle=106, High=39) and their awareness, satisfaction, cooking method, and utilization status of medicial cuisine were assessed. Regarding awareness, responders showed highest mean score of 4.57 in perceiving medical cuisines as healthy meal. The preferred cooking method includes medicinal cuisines as noodle, boiled in soy sauce, steaming, roasting, and dessert. Good taste, easy recipe, nutrition, and reasonable price were statistically significant reasons for their preference for medicinal cuisine. However, low preference of students for medicinal cuisine made it difficult to include them into school meals. Methods currently used to serve more medicinal cuisine include the application of different recipes using the same ingredients. The results of this study suggest that having dietitians with a higher preference for medicinal cuisine can serve as a strategy to increase the exposure of school students to medicinal cuisine. The development of recipes applicable to school foodservices by dieticians and the adoption of policies and education programs for medicinal cuisine by the government and associations are recommended.

Inhibitory activities of 264 methanol extracts, which were prepared from different parts of 210 kinds of wild and medicinal plants, against human thrombin were evaluated. Based on the anti-coagulation activity determined by thrombin time and activated partial thromboplastin time, the 14 extracts were screened. The fibrinolytic activity, heat stability and inhibition of other proteolytic digestive enzymes, such as pepsin, papain, trypsin and chymotrypsin, of the 14 extracts were further determined, and Ginko biloba (herba), Ephedra sinica (radix), Reynoutria elliptica (herba), Amomum tsao-ko Crevost (fructus), and Magnolia officinalis Rehd. et Wils (bark) were finally selected as possible plant sources for anti-thrombosis agent. These results suggested that medicinal and wild plants could be the potential source of thrombin inhibitor.

The purpose of this study was to investigate the possibility of Meles moles application as an edible functional food resource. This study was conducted to estimate the general nutrition composition, amino acid and minerals contents, fatty acid composition of Meles meles oil and the added fermented medicinal herbs liquid, and examine the cell toxicity effects in normal liver and kidney cells. The approximate composition of Meles moles oil was crude fat, 97.64％, crude ash, 1.99％ and crude protein, 0.37％. In the fermented liquid, the approximate composition was moisture, 96.08％, Carbohydrate, 1.53％, crude ash, 0.92％, dietary fiber, 0.65％, crude protein, 0.54％ and crude fat, 0.28％. The amino acid contents were 2.67 and 80.9mg％ in the oil and liquid, respectively. The singularity of the unsaturated fatty acid contents attracted our attention. Especially, the polyunsaturated fatty acid compositions were 32.28 and 54.98％ in oil and liquid, respectively. Negative effects were not found form the results of the cell toxicity respection. These results imply that Meles effects oil and the added fermented medicinal herbs liquid can be used as possible food resources and functional food materials.

Data from the 2001 Korea Health and Nutrition Examination Survey, a nationally representative, cross-sectional survey, were analyzed to assess prevalence of health intended food use overall and in relation to socio-demographic and lifestyle characteristics. Health intended food were classified into four broadly defined categories: vitamin and mineral supplements, health aid food, animal protein based restorative food and medicinal plants. Thirty three percent of adults aged 20 years or older reported taking health intended food in the past year : twenty four percent took vitamin or mineral supplements and medicinal plants were taken by 17 % of adults, health aid food by 15% and animal protein based restorative food by 6%. In multivariate logistic regression, female gender, older age, more education, regular exercise and non smoking were associated with greater use of vitamin or mineral supplements. Dietary quality was significantly associated with use of vitamin or mineral supplements or health aid food but not with use of medicinal plants or animal protein based restorative foods. Obese persons were less likely to take vitamin or mineral supplements. These findings suggest that epidemiologic studies of diet, demographic or lifestyle and health take health intended food use into account because of high prevalence of use of the food by the population and differential use of the food by socio-demographic and lifestyle characteristics.

Medicinal herbs have long been used as a remedy for diverse diseases in Asia owing to their various pharmacological effect. In this study, the immuno-enhancing activity of medicinal herbs was investigated using macrophage cell lines. Specifically, we examined the effects of extracts of twelve medicinal herbs on nitric oxide (NO) production in RAW 264.7 cells, and selected five that were highly effective (Glycyrrhiza glabra, Rehmannia glutinosa, Angelica gigas, Platycodon grandflorum, and Actinidia polygama) for further immune related studies. The effects of extracts from five theses medicinal herbs, which were mainly composed of polysaccharides and proteins on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and the Molt-4 T cell line were investigated. The extracts of all investigated medicinal herbs increased the production of NO and cytokines such as tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6) and interleukin-10 (IL-10). Additionally, they slightly increased the proliferation of T-cells when compared to the control. Overall, the result of this study suggests that the five medicinal herb extracts investigated herein are useful natural immune enhancing agents.
