  • The foods such as rice, peanuts and plums etc. are recognized as a direct way to keep health and to cure diseases based on the theory of that the medicine and foods are from the same source, not just to maintain life, therefore due to this reason, the dietary treatment is currently gathering strength with patients who are suffering from chronic diseases. Especially, 1 trust that the practical application of functional foods and taking medicine must be highly effective in curing diseases or relieving symptoms. In order to produce the superior functional foods by medicinal herbs, we should to make a greater effort to research the harvest time of material, drying and keeping method, and additionally try to develop the standard of food material and various drugs manufacturing continually.

  • The bioassay-guided fractionation of MeOH extract from Naematoloma fasciculare afforded a petroleum ether fraction (NFPF) and four known compounds, which showed good antitumor activities to inhibit MCF-7 cell line proliferation in vitro and tumor growth in $H_{22}$ implanted mice in vivo. In addition, a number of unsaturated aliphatic acids were identified in NFPF by GC analysis. These results showed that NFPF inhibits tumor growth through the activity of unsaturated aliphatic acids together with two active compounds, ergosterol peroxide (1: 62.17 mg/g in NFPF) and ergosterol (2: 3.13 mg/g in NFPF), and indicate the potential utility of NFPF as an antitumor drug.

  • The stability of the properties of magnetite particles in novel medicinal magnetic ointments of multipurpose application was examined by Mossbauer spectroscopy. Comparative analysis of the results obtained by model fitting of $\^$57/Fe nuclei spectra with those known for the system Fe$_3$O$_4$-${\gamma}$-Fe$_2$O$_3$ allowed to identify the phase composition of the particles. This composition, as well as that of the initial pure component in the form of a highly dispersed fraction (∼ 100${\AA}$), differs noticeably from the stoichiometric one. Despite their small sizes, the particles exhibit no superparamagnetism ( in the temperature range from 95 to 300k ). Radiative sterilization of the ointments has no effect on the magnetic component composition.

  • Korean ginseng (Panax ginseng C. A. Meyer) is an representative medicinal herb. It is classified as an adaptogen, helping the body to adapt to stress, improving stamina and concentration, and providing a normalizing and restorative effect. However, cultivation and breeding of the plant is very difficult because it requires at least 4-year cultivation from seed germination to root harvest.(중략)

  • The current study aims to analyze the acceptance of International Standard Terminology (IST) related to herbs and formulas used in Korea. It also intends to examine limitations of each term source by linking texts for herbal medicine research and formula research used in schools of oriental medicine with medicinal substance-formula classification names within the IST framework. This study examined 64 medicinal classification names of IST, including synonyms, 41 formula classification names, 65 classification names of "Herbal Medicine Study," 89 medicinal classification names of "Shin's Clinical Herbal Medicine Study," and lastly 83 formula classification names of "Formula Study." Data on their chief virtue, efficacy and characteristics as medicinal substances were extracted from their definitions, and such data were used to perform Chinese character-English mapping using the IST. The outcomes of the mapping were then analyzed in terms of both lexical matching and semantic matching. In terms of classification names for medicinal substances, "Herbal Medicine Study" had 60.0% lexical matching, whereas "Shin's Clinical Herbal Medicine Study" had 48.3% lexical matching. When semantic matching was also applied, "Herbal Medicine Study" showed a value of 87.7% and "Shin's Clinical Herbal Medicine Study" 74.2%. In terms of formula classification names, lexical matching was 28.9% of 83 subjects, and when semantic matching was also considered, the value was 30.1%. When the conceptual elements of this study were applied, some IST terms that are classified with other codes were found to be conceptually consistent, and some terms were not accepted due to different depths in the classification systems of each source.

  • Radix Astragali, the root of Astragalus (A.) membranaceus, has been applied in a variety of diseases for a long time in Asian countries such as Korea and China. In addition, the aerial parts such as leaves and stems of A. membranaceus have received a great deal of attention. Recently, the polysaccharide fraction showing a potent immunomoduating activity was isolated from the aerial parts of A. membranaceus. Thus, the aerial parts of A. membranaceus would be worthy enough for a food material and a dietary supplement. However, they should be safe even though valuable. In our previous study, it was estimated that NOAEL for female rats are 5000 mg/kg/day of the crude polysaccharide fraction from A. membranaceus-aboveground parts. As a series of safety evaluation, genotoxicity test for the crude polysaccharide fraction was carried out in this study. In conclusion, the three genotoxicity assays provided strong overall support that the crude polysaccharide fraction lacks mutagenic and/or clastogenic potential under the GLP-based test conditions. This indicates the aerial parts of A. membranaceus would be safe enough for a food material and a dietary supplement.

  • Rehmannia glutinosa is one of the most important medicinal crops in Korea. However, various plant pathogens including Fusarium sp. cause great damages and cause enormous economic losses. Therefore, this study was conducted to select Fusarium resistant plants by using mutagen-treated Rehmannia glutinosa. The plant material used was a native accession of Rehmannia glutinosa. As a result, among the Rehmannia glutinosa treated with various concentrations of EMS, R. glutinosa treated with 0. 03M EMS showed higher resistance against infection of F. oxysporum in pot tests, and Rehmannia glutinosa plants treated with 0.12M EMS showed higher resistance against infection of F. oxysporum in field tests.

  • This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were $\alpha$-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

  • Understanding the purpose and results of a Korean Envoy's medical bureaucrat (attendant) travel to China. Unlike other Envoy's medical bureaucrats, envoy's trade made profits for those who participated. This article investigates the protocols of a Korean Envoy's medical attendant which include: (1) A prominent family member or high-ranking official does not participate in the Envoy's medical bureaucrat, either himself or his descendants. This denies the general theory that the medicinal material trade helped the economic status of medical officials. (2) Envoy's medical bureaucrat is a high percentage of interpreter bureaucrat in the households of father, mother, and wife. This suggests that the information about the envoy schedule and the benefit of the envoy may have been exposed in advance. This is related to the fact that the interpreter bureaucrat is the center of the envoy trade. (3) In the nineteenth century, envoy's medical bureaucrats were more frequent among close relatives, such as father-son relationship, than in the previous century. This study restored the lineage and purpose to the medical bureaucrat's travel to China, and provides a list of Envoy's medical bureaucrat through historical data, and analyzed the household and previous office. In this regard, it can be seen that some households, which are not dominant medical bureaucracies, have pursued profit through medicinal material trade. However, it is difficult to generalize to the whole of the medical bureaucracy.
