Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

The Korean folk medicine 'Cho Pi Na Mu' has been used orally to tuberculosis, neuralgia, acute and chronic gastritis and arthritis. In order to clarify the botanical origin this crude drug, comparative anatomical studies were made on the branches of Zanthoxylum species growing wild in Korea, i.e. Z. coreanum, Z. piperitum, Z. piperitum var. pubescens, Z. planispinum, Z. schinifolium, Z. schinifolium var. inermis, Z. schinifolium var. microphyllum. As a result, it was clarified that 'Cho Pi Na Mu' was the branch of Z. piperitum.

Aconites distribute widely in northern hemispere of the earth reaching to arctic zone from warm and temperate one. Hitherto, these tuberous roots, 'Cho O', have been known to be famous plant poisons and essential important drugs possessing many remedial effects in each region of the world, especially in Korea and China. In Korea, although these plants grow widely in whole districts, their classifications are quite obscure. Especially, Aconitum triphyllum $N_{AKAI}$ is distributed whole districts. To clarify the botanical origin of 'Cho O', we studied on the anatomical characteristics of Aconitum triphyllum $N_{AKAI}$ growing wild in Korea. As a result, the environmental varieties of A. triphyllum $N_{AKAI}$ were recognized.

Korean folk medicine "EJePiNaMu" has been used orally to cure neuralgia, rheumatism and common cold. To clarify the botanical origin of this crude drug, comparative anatomical studies were made on the branches of Zanthoxylum species growing wild in Korea, i.e. Z. coreanum, Z. piperitum, Z. piperitum var. pubescens, Z. planispinum, Z. schinifolium, Z. schinifolium var. inermis, Z. schinifolium var. microphyllum. As a result, it was clarified that "EJePiNaMu" was the branch of Zanthoxylum planispinum.

The roots of Rosa rugosa have been used to treat diabetes mellitus in the folkloric society of Korea. To demonstrate the active component for the rat obesity induced by high fat diet for 6 weeks, the phytochemical fractionation and the pharmacological activity test were performed on this crude drug. It was shown that the methanolic extract and its EtOAc fraction inhibited the weight increase of the rat body, abdominal fat pad and hyperlipidemia at 200 mg/kg dose. Further, the triterpenoids, euscaphic acid and tormentic acid, isolated from R. rugosa roots were active at 30 mg/kg in the same assay. The two components shifted serum total-, HDL, and LDL-cholesterol levels toward the values of the unteated group, suggesting that the active compounds has hypolipidemic effects. The rats fad euscaphic acid and tormentic acid also reduced thiobarbituric acid-reactive substance (TBARS) and hydroxyl radical in the rat blood and increased superoxide dismutase activity compared to the control. TBARS values and carbonyl contest of the hepatic protein were reduced by treatment with the two triterpenoids. Antioxidative enzyme (SOD, glutathione peroxidase, and catalase) activities in hepatic were increased by treatment of rats with the triterpenoids, which suggests that triterpenoids inhibited the reduction of hepatic antioxidative activity caused by high fat diet. Taken together, these results support that euscaphic acid and tormentic acid improve a high fat diet-induced hyperlipidemia via the activation of antioxidative mechanism.

Objectives : The purpose of this study is to find a reasonable solution to a current status of drug classification between the drugs of western conventional (allopathic) medicine and Korean medicine. A clear and distinct concept on the drugs of allopathic medicine and Korean medicine based on reasonable concepts and broad consensus is a pressing issue in Korea, and will facilitate the development of herbal medicinal products and pharmaceutical industry. Methods : Considering the issue of drug classification from domestic and international regulations, we reviewed the current Drug Law of Korea and China, Guidance for Industry, Botanical Drug Products of USA, Directive 2004/24/EC of the European parliament and of the council. Results : In Korea, the drug classification of allopathic medicine and Korean medicine is quite vague even though differential licensure system is enforced for the clinicians of allopathic medicine and Korean medicine field. According to the definition in the Drug Law, the scope of Korean medicine drug is so broad that even a drug made of single-compound material, as well as herbal extract of crude mixture, is regarded as a drug of Korean medicine, as long as the material may be separated from medicinal herbs, animal tissues, or mineral resources. Only new compound not found in natural resources are outside of the scope of Korean medicine drug. In USA and EU, medicinal products manufactured from herbs are approved by separate regulations for the herbs with special waivers. In China, the category of new medicine and the definition of allopathic medicine and traditional chinese medicine are clearly specified and classified. Conclusions : As medicines are validated therapeutic materials for efficacy and toxicity, we suggest that generally the concept of conventional medicines is based on a single compound that has been synthesized and individually validated and that of Korean medicines is based on a compound extracted from natural materials or a complex of compounds that has been validated as a whole in its totality.

Chinese crude drug 'Kang Whal' has been used mainly as a headache in common cold, rheumatic arthralgia and aching of the back and shoulder. To clarify the botanical origin of Kang Whal from Korea, the anatomical characteristics of Ostericum koreanum Maxim. and Notopterygium incisium Ting ex H.T.Chang were studied. As a result, it was clarified that Kang Whal from Korea was the underground part of Ostericum koreanum.

Antimutagens, including diverse compounds of botanical origin, offer some promise of reducing the risk posed by exposure to mutagens. Caution is warranted, however, as there may sometimes be a delicate balance between antimutagenic effects and potentiating effects of the same compounds. We studied effects of the antimutagens spermidine (SPD) and cysteamine (CSM) on the genetic activity of the radiomimetic cancer chemotherapy drug bleomycin (BLM).(omitted)

Chinese crude drug 'Dang Gui' has been used mainly as a tonifying the blood, promoting blood circulation, relieving pain and moistening the bowels. To clarify the botanical origin of 'Dang Gui' from Korea, the anatomical characteristics of Angelica gigas, Angelica sinensis and Angelica acutiloba were studied. As a result, it was clarified that 'Dang Gui' from Korea was the root of Angelica gigas.

The essential oil (EC-oil) obtained from the buds of Eugenia caryophyllata (Myrtaceae) was examined for its free radical-scavenging activity, cytotoxicity, and in vivo toxicity. To find the xenobiotic properties of EC-oil, serum thiobarbituric acid reactive substances (TBARS) level and hepatic drug-metabolizing enzyme activities were measured. It was found that EC-oil displayed xenobiotic properties like bromobenzene. The cytotoxicities of eugenol and of the EC-oil were greatly attenuated by the sulfhydryl-containing N-acetyl-L-cysteine (NAC), suggesting that eugenol was susceptible to nucleophilic sulfhydryl. In addition, eugenol also showed potent free radical-scavenging activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Moreover, methyleugenol considerably exhibited less cytotoxicity and less potent free radical-scavenging activity than eugenol, and the cell viability of the methyleugenol was more increased with NAC treatment than the eugenol. These results indicate that the phenolic OH in eugenol may play a crucial role in both cytotoxicity and free radical-scavenging activity. The fashion on oxidative stress and hepatic drug-metabolizing enzyme activities of eugenol resembled those of bromobenznene.
