인류는 자연으로부터 식량과 질병 치료를 위하여 자연스럽게 약초를 얻을 수 있었다. 약 6만 년 전 네안데르탈인의 무덤에서 오늘날 향료로 쓰이는 약초가 발견 될 정도로 인류가 약초를 이용한 역사는 오래 되었다. 약초는 난치병, 노화, 성인병 등 현대의학에서 미비점을 보완하는 대체의약 산업의 원료이자 새로운 생물자원의 보고로서, 그 중요성이 커지고 있다. 새로운 생물자원 소재로 약초는 약용성분을 함유한 식물자원의 확보 및 개발 등 고부가산업의 소재로 선진국에서 연구개발의 경쟁이 치열하며, 약초산업은 천연소재 신약과 기능성 식품, 화장품, 생활용품 등으로 확대되고 있다. 의약품 분야에서는 새로운 시대의 중요한 생명산업으로서 약초는 한약뿐 아니라 신약 개발을 위한 소재로도 부각되고 있으며, 항암제인 택솔, 신종플루 치료제인 타미플루 등 천연물 약의 가능성은 이미 증명되었다. 식품 분야에서는 재배기술 발달과 웰빙 트렌드 속에서 약초는 신선채소와 기능성 식품으로 변신하고 있다. 한약재의 이미지를 벗어난 약초는 음료와 과자, 술 등으로 활용되고, 비빔밥 등 다양한 약선음식으로도 개발되고 있다. 산업소재의 활용분야에서는 약초는 특히 화장품 산업의 소재로 각광받고 있다. 이미 다양한 화장품 회사에서 한방화장품을 출시하여 세계 속으로 진출하고 있다. 또한 약초는 천연 색소이자 생활 용품의 소재로 활용되고 있는데, 약초를 활용한 염색약과 여성 생리대, 샴푸 등의 인기가 높다. 약초산업의 부가가치 증대를 위하여 한약재 위주의 약초산업을 천연물 신약, 기능성 식품, 화장품, 산업 소재 등 고부가가치 시장으로 확장시키고, 우리 약초 산업의 세계화를 추진해야 한다. 연구개발 투자 확대와 빠르게 변화하는 시장을 반영하여 연구 방향을 수립하고, 산학연 및 생산자단체 등과 새로운 약초 산업의 블루오션 창출을 위해 협력을 해야 할 것이다. 또한 약초의 생산기술 안정화를 통해 산업화 기반을 구축하여, 약초 공급의 안정화, 약초 생산 농가 소득 안정화가 필요하며, 마지막으로 변해가는 약초 산업의 트렌드에 부응할 수 있는 품질관리와 유통 질서 확립을 위한 정책과 제도의 선진화가 뒷받침 되어야 할 것이다.

The antibacterial activities of nine oriental herbal medicine extracts were measured against seven kinds of bacteria known to cause food poisoning and disease. The extracts were prepared with distilled water using an autoclave ($121^{\circ}C$ for 30 min). The extraction yields of nine oriental herbal medicines were in the rage of 0.5%-33.4%. The antibacterial activities were evaluated using the paper-disc method. Extracts of Hwangryeon, Jiyu, and Ohbaeja showed antibacterial activities while the others did not. Extracts of Coptis japonica, Hwangryeon, and Sanguisorba officinalis, Jiyu showed antibacterial activities only against Clostridium perfringens and Listeria monocytogenes. Extracts of Rhus javanica, Ohbaeja showed the strongest antibacterial activities against all the bacteria tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of R. javanica extracts were in the range of 2.4~20 mg/ml for the bacteria tested. In conclusion, the extract of R. javanica showed superior antibacterial activities against the seven bacterial strains tested. The MIC and MBC values for each bacterium were represented as strain names (MIC, MBC), which were Bacillus cereus (11.2, 20), Clostridium perfringens (2.4, 4.7), Escherichia coli (9.1, 9.1), Listeria monocytogenes (11.1, 20), Salmonella typhi (4.7, 9.1), Staphylococcus aureus (2.4, 4.7), and Vibrio parahaemolyticus (2.4, 5.3). Further purification and study of this antibacterial material would be helpful for developing antibiotics or promoting synergistic effects with known antibiotics, producing antibacterial material for lengthening the shelf-life of food, and so on.

Oxidant stress is a well-known pivotal parameter for the degenerative immune diseases including asthma, atopic dermatitis, and rhinitis. In order to screen for anti-asthma agents effectively, we first established the infrastructure of high throughput screening(HTS) for anti-oxidant agents from agricultural products and/or oriental medicine library extracted with water, methanol, dimethyl sulfoxide, ethyl acetate and juice, Using the screening system, we found that Chaenomelis langenariae, Rhus javanica L., Camellia sinensis, Helianthus annuus and Angelica utilis Makino had strong anti-oxidant activity. Moreover, Helianthus annuus, Rehmannia glutinosa Libo and Angelica utilis Makino have protection activities by treatment of an oxidant hydrogen peroxide. Together, these results suggest that screened agents could be potential agents against asthma, although the in vivo studies should be clearly tested.

To evaluate whether active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have potential in ameliorating allergic symptoms in mice, we tested anti-allergic activities in a dinitrofluorobenzene (DNFB)-induced allergic mouse model. DNFB-induced allergic symptoms werereduced to about 50% of control levels by active components produced by solid fermentation of Phellinus baumii and Ephedra sinica, as evaluated by measuring the width of epidermal swelling. H&E staining also revealed that these active components markedly reduced allergic symptoms in the epidermis of the ear. The results indicate that active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have the potential to ameliorateallergic symptoms, and may be useful biomaterial(s) in the neutraceutical or cosmeceutical industry.

We studied new product presentation strategies for cheongyang Lycium chinense, and the attributes of consumers purchasing cheongyang; this is a popular herbal medicine. Attributes are characteristics or properties of a product, and generally refer to features regarded as evaluative criteria during decision-making. The key phrases found on data analysis were "free from disease" and "health". Makers or producers must conduct research and development to promote consumer demand for Lycium chinense, and they must overcome any consumer-held negative images of Lycium chinense attributes.

Finding a means to discriminate the commercial herb medicines when they were dried and sliced is a very important and imminent project in Korea. To differentiate plant origins and the commercial herb medicines of Atractylodes japonica and A. macrocephala, two discriminative methods using anatomical characteristics and SCAR marker were applied. It was possible to discriminate plant origins and the commercial herb medicines between A. japonica and A. macrocephala by anatomical characteristics: development of periderm, layer of stone cell, distribution of laticiferous vessels, development of xylem fiber in xylem ray, contained quantity of clustered crystals and others. While, two SCAR markers were developed from RAPD clones: SAjR2 (600 bp) from AjR2 and SAmR1 (1,200 bp) from AmR1. These two markers were enough for discrimination plant origins and the commercial herb medicines between A. japonica and A. macrocephala. The result of application of anatomical characteristics and SCAR markers to investigate current status in domestic herb market, Daegu and Kumsan herb market, it was identified to be current herb medicines of A japonica.

The purpose of this study is to provide basic data on the safety of Poria cocos, a major Korean herbal medicine, and to establish tolerance levels for hazardous substances. Residual pesticides (321 types), heavy metals (7 types), radioactivity (3 types), and ash content were analyzed in 10 Poria cocos products distributed in Korea (5 domestic and 5 in China). Of the residual pesticides, cypermethrin was detected at 0.03 mg/kg in one domestic sample and was below the standard value. Of the heavy metals, the levels of Zn, Pb, Ni, Cu, Hg, and Cr were below the standard values in all samples. Hg was not detected in any sample. Cd was detected at 0.011 mg/kg in one Chinese sample. The radioactivity concentration was also below the MDA value in all P. cocos samples. The ash content was less than the standard value of 1.0% in all P. cocos samples. The findings indicate that P. cocos distributed in Korea is safe. However, because P. cocos is always exposed to harmful substances because of the nature of its cultivation in the soil, it seems necessary to establish systematic management standards for the entire production stage, such as cultivation, storage, and distribution.
