As the consumers' anxiety for food increases, the interest in food safety also increases. To satisfy the public requirement on food safety, the government is trying to set up a food safety standard by using regulations and certification systems. However, there is still difficulty in building up complex traceability systems for medicinal crops including ginseng due to the low participation of farming industries. The purpose of this empirical research is to draw factors that impede the GAP adoption of ginseng farms. By comparing the average attitude and intention to adopt the ginseng farms' depending on its characteristics through a two-tailed test, it was drawn that continuous farming education can positively influence the GAP adoption of the ginseng farms.

There is great demand of nutraceutical secondary metabolites in the world so as to feed the population by improving agricultural production with new varieties of food crops but what is still more important is to add nutrition into the food. Physalis minima, plant of Solanaceae family, contain certain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals that are generally regarded as safe. These chemicals are almost monopoly of the plants of Solanaceae. The leaves, stem and roots of P. minima have been examined to yield several steroids, identification of which has been discussed in this paper. These withasteroids contribute to the potential nutraceutical and health function value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.

Historical review on Korean vegetables was performed to illustrate the important position of the vegetables in Korean food culture. It is assumed that the cultivation of vegetable crops had been begun along with crop production. Korean people placed great importance on quality of vegetables including flavor and texture. It was also confirmed that vegetables had been cultivated and preserved by scientific methods. They grew vegetables at their leisure and knew to utilize medicinal effects of vegetables. This review reveals Korean ancestor's wisdom to use vegetables as foods for the relief of the sufferers from famine at the time of spring food shortage or crop failures.

It is of utmost importance to feed the current world population by improving agricultural production with newer varieties of food crops, but what is still more important is to add nutrition into the food. Some of the plants, which are currently growing in the wastelands, contain certain phytochemicals which add to their neutraceutical and health value. These plants contain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals. These chemicals are almost exclusively found in plants of the Solanaceae family; one of which, Physalis minima, contains several with asteroids. The aerial parts and roots of P. minima have been found to contain several steroids, identification of which is been discussed in this paper. These with asteroids contribute to the functional value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.

Potatoes have been recognized for a long time as one of the major food crops as well as horticultural crops. Potato production as a table food has been decreased in developed countries, while it has been steadily increased in the third world countries for it importance as food source. It is a new trend to look for the food, not only as a feeding crop but also healthy food. It is also time for the potato producers to look for the potato having high economic value as found in medicinal plants. There are great diversities in potato species, indicating that valuable compounds can be found in different amounts, depending on potato species. We screened the cultivars, breeding clones, and germplasms based on the vitamin C, Vitamin E, antioxidant compounds, diverse sugar types, important amino acids, and other valuable compounds. We could select the breeding clones KC003, 98Wl17, 99j717, and Vally 8 (A group) due to their high levels of antioxidant compounds, and it can be said that most of the red and purple colored potato clones belong to the A group. In the contents of essential amino acids, ‘Taebook Valley’,‘Summer Valley’ and other breeding clones were found to be high in amount. We also made crosses between breeding clones with high biological function and low agronomic traits and low biological function with high quality in agronomic characteristics . The patterns of genetic trends of these offsprings in comparison with their parents will be reported as well. And the potential of using potato as antibody production of anti-cancer will be discussed.

This study is part of research to develop the technology for managing major medicinal crops after harvest. We studied the optimal germination conditions of $Cynanchum$ $wilfordii$ (Maxim.) Hemsl. The mean germination time (MGT) of $C.$ $wilfordii$ seeds was higher after soaking for 4 days after storage at $5^{\circ}C$ for 8 weeks, than with germination at $25^{\circ}C$ (3 days). However, the germinative energy (GE) decreased as the number of days soaking increased. The greatest germination rate ($83.3{\pm}8.8%$) was at $25^{\circ}C$ with no soaking of seeds stored at $-20^{\circ}C$ for 8 weeks. Based on these results, we characterized the germination conditions of a major medicinal crop.

본 연구에서는 해조류 자원의 산업적 활용 소재로서의 가치 및 기능성 식품 및 사료 첨가 소재로의 개발을 위한 기초 자료를 제시하고자 국내에 서식하는 10종의 해조류 열수추출물을 이용하여 항염증 활성 및 마우스 대식세포주와 어류 세포주의 세포생존율에 미치는 영향을 확인하였다. 그 결과 S. japonica 100, 1000 ㎍/mL과 G. tenax 1000 ㎍/mL 농도에서 마우스 대식세포주를 LPS로 자극하였을 때 생성되는 NO를 유의적으로 감소시키는 것을 관찰하였으며, 나머지 8종의 해조류 추출물은 실험 농도에서 LPS에 의한 NO 생성에 영향을 미치지 않았다. 고농도에서 항염증 활성을 보인 S. japonica 및 G. tenax 열수추출물은 염증 인자를 조절할 수 있는 기능성 후보 소재로서 분획별 생리활성과 유효성분 규명의 연구가 요구된다. 본 연구 대상 해조류 추출물에 대한 안전성 기초 자료로서 마우스 대식세포 및 넙치 배아 유래 세포 세포생존율에 미치는 영향을 평가한 결과, P. tenera 고농도 (1000 ㎍/mL) 처리군을 제외하고 모든 해조류 추출물은 마우스 대식세포의 생존율에 영향을 주지 않았으며, 모든 해조류 추출물에서 5000 ㎍/mL까지 넙치 배아유래 세포에 대한 세포독성이 나타나지 않았다. 본 연구 결과는 후속 연구를 통해 해조류의 다양하고 복잡한 구조의 생물 활성 화합물의 생체 내 메커니즘을 규명함으로써 기능성 소재 개발을 위한 기초자로료 활용될 수 있을 것으로 기대하며, 본 연구의 대상 10종의 국내 해조류 자원 중 S. japonica과 G. tenax은 잠재적인 천연 항염증제로서 안전한 식품 및 사료 첨가 소재로서의 가능성을 제시한다.

Chaga mushroom and Cheonggukjang have been used in alternative medicine. In this study, we determined the anti-obesity effects of fermented Chaga-Cheonggukjang (FCC), an extract prepared by secondary fermentation of a mixture of Cheonggukjang and Chaga by Lactobacillus acidophilus on highfat diet (HFD)-induced mice. Male ICR mice were fed a normal diet or HFD in the presence or absence of 3% and 5% FCC (FCC3 and FCC5). After 3 months, the mice were sacrificed, and serum and tissue samples were examined. Body weight and epididymal fat pad (EFP) weight were significantly lowered in FCC3 and FCC5 groups compared to those in the HFD control group. FCC supplementation suppressed serum triglyceride (TG) and increased serum HDL levels. Serum GOT, GPT, leptin levels and hepatic COX-2 mRNA expression were significantly higher in the HFD groups, and these increases were significantly attenuated by FCC supplementation. FCC suppressed body weight and EFP weight gain, as well as inflammatory responses in the liver in HFD-fed mice. Thus, FCC supplementation may have protective effects for obesity-related disease.
