This project is planned to grasp the present situation of traditional medicine part in our country and to study protection method about this by the intellectual property which is the international concerning point recently. Through this, we will be able to devise means to deal with protection method of traditional medicine being developed by WIPO now. Traditional medicine field In our country Is organized with specific condition separated into the part of institution and the part of non-institution. So, because of the closed peculiarity, we have experienced the difficulties to understand the real facts about traditional medicine. We cannot be indifferent to the matter anymore. Because the expectation of object people is high, we could expect the realization of research content. In 1 detail project, we investigated the situation of traditional medicine in our country through various collecting methods for excavation of oriental treatment technique and herb medicine which is worth protecting. With it, we sorted again into 56 kinds of 11 parts through analysis of validity in the way of oriental medicine. And we tried to link this up 2 detail project which is about legal and institutional guarantee concerning protection. furthermore, we tried to find approach ways for security of objectivity into 4 steps with the example of model disease. we could complete practical classification of traditional medicine in our country. In 2 detail project, we studied the protection method by the intellectual property through research result in 1 detail project. For this, we observed an outline of the intellectual property including a patent application analysis in folk traditional medicine part, and problems of traditional medicine protection and world trend by traditional knowledge protection tendency and the patent law In domestic traditional medicines, the aspects unprotectable with the patent law now were remained. So, we suggested supplementary plan. And we also suggested the freedom of utilization between traditional medicine possession countries (in-situ utilization) and the demand compensation payment for a third country (ex-situ utilization) in connection with international movement.

The medicinal herb Oldenlandia diffusa is known as a folk medicine for the treatment of hepatitis, sore throat, appendicitis, malignant tumors and urethral infection in Southern China and Korea. Another species O. corymbosa, is also used for the therapy of the similar conditions, however, only O. diffusa is referred to the medicinal herb by Chinese Pharmacopoeia. Due to their similar morphology, O. diffusa and O. corymbosa are often misidentified. To easily identify O. diffusa from O. corymbosa, the phylogenetic utility of nuclear ribosomal DNA (nrDNA) internal transcribed spacers (ITS) were investigated among different O. diffusa and O. corymbosa populations in Korea. The nrDNA ITS sequence of O. diffusa contained 791 bp, with GenBank accession number of JF837601-JF837602. The nrDNA ITS sequence of O. corymbosa was 785-786 bp, with GenBank accession number of JF837603-JF837611. The results showed that there are some certain divergences in the ITS region sequence between both species, even among different populations of the same species. Particularly, O. corymbosa ST-4 population showed the highest dissimilarity of the ITS region sequence with other nine populations of O. corymbosa and two populations of O. diffusa. This consequence makes us further understand the molecular diversification between O. corymbosa and O. diffusa, and help to promote the correct use and safety.

Dendropanax morbifera (Araliaceae) is an endemic species in Korea and distributed in the southern part of Korea. The roots and stems of this plant have been used for folk medicine for the treatment of migraine headache, dysmenorrheal, and remove wind dampness and for Vanishes production. Production of adventitious roots in D. morbifera by in vitro cultures could be used as alternatives materials. Leaf, stem, and root segments from D. morbifera seedling were cultured on Murashige and Skoog (MS) medium supplemented with 3.0 mg/L IBA and 30 g/L sucrose. After 4 weeks of culture, the highest induction of adventitious roots was obtained from the leaf segment. Frequency of adventitious root formation on medium with various kinds of auxins (IAA, NAA, 2,4-D, and IBA) and various concentrations of IBA (0, 0.1, 0.5, 1.0, 3.0, and 5.0 mg/L) was tested. The maximum induction of adventitious root was obtained on medium with 1.0 mg/L IBA. In liquid culture, growth of root was best 1/2MS medium supplemented with 1.0 mg/L IBA and 30 g/L sucrose. Adventitious roots were cultured in 5 L bioreactor containing 1/2 MS medium supplemented with 1.0 mg/L IBA and 30 g/L sucrose and mass-production of adventitious roots was successfully achieved. This study demonstrated for the first time to produce adventitious roots in D. morbifera.

Melanogenesis is a physiological process resulting in the synthesis of melanin pigments, which play a crucial protective role against skin photocarcinogenesis. The heart wood of Caesalpinia sappan L.(C. sappan) has long been commonly used in Oriental folk medicines to promote blood circulation, and as an emmenagogue, analgesic or anti-inflammatory agent as well as a remedy for thrombosis. From the heartwood, many constituents have been purified and among them, brazilin and hematoxylin are two of the most abundant. This present study was designed to investigate the inhibitory effect of butanol extract from C. sappan on proliferation and melanogenesis in Melan-a cells. After 48 h treatment of these cells with various concentrations of butanol extract, the cells showed a dose-dependent inhibition in their proliferation without apoptotic cell death. Therefore, the growth retardation by the extract may be due to the cell arrest or cell differentiation. We also estimated total melanin content as a final product and activity of tyrosinase, a key enzyme, of melanogenesis in Melan-a cells. The melanin content and tyrosinase activity were deσeased in extract-treated cells in a dose dependent manner compared to control group. The butanol extract also resulted in a decrease of melanin content in ${\alpha}-melanocyte-stimulating$ hormone (MSH)-induced melanogenesis, indicating that butanol extract of C. sappan could be developed as skin whitening components of cosmetics.

The usage of wild ginseng (Panax ginseng C.A. Meyer) has been limited due to short supply and high price. Therefore, sufficient production as well as efficient extraction of mountain ginseng are required for the development as products. In this study, wild ginseng adventitious root cultures were prepared for efficient production with advantages of fast growth and stable production. Treatment of methyl jasmonate (MJ) to wild ginseng adventitious root cultures increased the extraction yield and antioxidative activity. Further investigation on effect of extraction conditions suggested the importance of ethanol concentration on antioxidative activity and extraction yield of MJ-treated wild ginseng adventitious root cultures. Optimized extraction condition of MJ-treated wild ginseng adventitious root cultures for maximum extraction yield and antioxidative activity was determined using response surface methodology with three-level-three-factor Box-Behnken design (BBD). Extraction of 1 g MJ-treated wild ginseng adventitious root culture with 30 ml of 9% ethanol at $30^{\circ}C$ produced 310.2 mg extract with 71.0% antioxidative activity at $100{\mu}g/ml$. Taken together, MJ-treated wild ginseng adventitious root culture is valuable source for wild ginseng usage and optimized extraction condition can be used for the development of functional products or folk remedies.

Dolichos biflorus Linn. (Fabaceae), commonly known as Horse gram is a medicinal plant, used in folk medicine for treating kidney stones and diabetes mellitus. The purpose of the present study was to investigate the effects of daily oral feeding of various doses of methanolic extract of Dolichos biflorus seeds (DB) for 42 days on blood glucose concentrations and kidney functions in Alloxan-diabetic rats. Plasma glucose levels, body weight, serum creatinine, and urinary albumin levels were monitored on $15^{th}$, $29^{th}$, $43^{rd}$ day. Renal hypertrophy was assessed as the ratio between the kidney weight and body weight of the rats. Plasma glucose concentrations in Alloxan-diabetic rats were significantly reduced by the administration of DB (350 mg/kg) and DB (700 mg/kg) on day 15 and onwards (P < 0.01). After 15 days of Alloxan administration urinary albumin levels (UAE) were over 5 fold higher in diabetic controls as compared to normal controls. Treatment with DB significantly prevented the rise in UAE levels from day 15 to 43 in comparison to diabetic controls (P < 0.01). Renal hypertrophy was significantly higher in diabetic controls as compared to non-diabetic controls. Treatments with DB (350 mg/kg) and DB (700 mg/kg) significantly prevented renal hypertrophy (P < 0.01) as compared to diabetic controls. DB (175 mg/kg) failed to modify renal hypertrophy. Thus the present study indicates that methanolic extract of Dolichos biflorus may be useful in management of hyperglycemia and kidney functions in Alloxan-diabetic rats.

GLEDITSIAE SPINA (GS) has been used as folk remedies traditionally for treatment of antiphlogistic and antifebrile agents. An ethanol extract and its fraction of GS were assessed to determine the mechanism of its antioxidant activity. Also, inhibitory effect of extract from GS and its fraction measuring the inhibitory effect on $Cu^{2+}$-induced human low-density lipoprotein (LDL) oxidation. GS ethanol extract and its fraction exhibited a concentration-dependent reactive oxygen species (ROS) and reactive nitrogen species (RNS) scavenging activities, including trolox equivalent antioxidant capacity (TEAC), OPPH radical, superoxide anion, hydroxyl radicals, peroxynitrite and nitric oxide, using different assay systems. Furthermore, the GS ethanol extract and its fraction showed dose-dependent protection of LDL oxidation induced by $CuSO_4$. In addition, the GS ethanol extract and its fraction were characterized as containing a high amount of total phenolics. These results suggest that GS ethanol extract and its fraction might be helpful for preventing oxidative stress and protecting LDL oxidation.

The Opuntia ficus-indica var. saboten Makino (Cactus) is a tropical or subtropical plant, which is cultivated or grows naturally in Jeju island. It has been widely used as folk medicine for burned wound, edema and indigestion. In addition, its extract has been claimed to have several biological activities including anti-inflammation in oriental medicine. In this study, we examined the antimicrobial activities of the methanol extract of Opuntia ficus-indica var. saboten Makino. The extract showed a broad spectrum of antimicrobial activity against pathogenic bacteria, including antibiotics resistant bacteria (MRSA, R-P. aeruginosa, VRE) and Propionibacterium acnes, yeast, and fungi. The extract retained the activity after heat treatment for 15 min at $100^{\circ}C$ and $121^{\circ}C$ and after extended storage, up to 10 weeks storage period at $4^{\circ}C$ and $25^{\circ}C$, also stably retained its activity. It showed a better inhibitoring effect to the growth of E. coli than sodium benzoate did it at the same concentration. Addition of various salts or metal ions did not affect on its antimicrobial activity. Therefore, the antimicrobial characteristics of the extract can be applicable as a natural preservative and an antimicrobial agent for bacterial disease.
