The objective of this study was to prepare bioactive ginseng yogurts containing compound K, which is transformed from ginsenosides, and to investigate the compound's cytotoxicity against tumor cells. Milk containing ginseng was fermented by Bifidobacteria KK-I and KK-2, and their activities for transforming ginsenosides to compound K were measured. Among the tested concentrations of ginseng in the milk, compound K was effectively produced in the 3% and 6% ginseng yogurts fermented for 48 hrs. These fermented ginseng yogurts were extracted with BuOH, and their cytotoxicities against tumor cells were examined. The BuOH extract of the yogurt made from the 3% ginseng milk showed cytotoxic activity against P388 and HeLa tumor cells. However, the nonfermented ginseng milk did not exhibit cytotoxicity against these cells. Therefore, we deem that the ginseng yogurt, which contained compound K, could be developed as a potential fermented drink product.

Effects of red ginseng acidic polysaccharides (RGAP) on immune system were studied. The proliferation of spleen cells was induced by RGAP treatment per se. Cotreatment of lipopolysaccharide $(100\;{\mu}g/ml)$ or concanavalin A $(1\;{\mu}g/ml)$ with RGAP further stimulated the spleen cell proliferation. BALB/c mice treated with RGAP showed a slight splenic hyperplasia and increased antibody forming cell response to sheep red blood cells. Flow cytometry analysis revealed an influx of macrophages in the mice treated with RGAP.

The ginsenoside content was compared with wild simulated ginseng (Panax ginseng) collected every season at 11 wild simulated ginseng plantations in Korea. As a result, the total saponin of 7 years old wild simulated ginseng showed the highest content of 4.5% in spring sampling wild simulated ginseng, 2.0% in summer sampling wild simulated ginseng, 1.2% in winter sampling wild simulated ginseng and 1.0% in autumn sampling wild simulated ginseng. And also, the total saponin of 10 years old wild simulated ginseng showed the highest content of 3.9% in spring sampling wild simulated ginseng, summer sampling wild simulated ginseng (1.8%), winter sampling wild simulated ginseng (1.6%) and autumn sampling wild simulated ginseng (0.6%). Therefore, the total saponin of spring sampling wild simulated ginseng was about 4.5 - 6.5 times higher than that of autumn sampling wild simulated ginseng regardless of cultivation period.

This study was conducted to investigate the effect of crude saponin of red ginseng and aqueous extracts from several medicinal herbs on the activity of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) in alcohol metabolism. In order to develop a liquid phase product a model product was prepared using functional plants. In case of red ginseng crude saponin, and some medicinal herbs(Puerariae radix, the flower of Puerariae lobata, the fruits of Hovenia dulcis Thunb., Morus alba L.) the relative activity of ADH was significantly increased, which was from 104～114%. The relative activity of ALDH was also significantly increased in the cases of the fruits of Hovenia duicis Thunb., Morus alba L. which was from 102∼106%. To improve of soju flavours by addition of liquid phase product, it is prepared three samples added a given content (0.28%) of chik, ssanghwa and kyungokgo flavour. The total acceptability test showed significant differences among three samples, and it is observed that the sample added ssanghwa flavour get the best grade. As the second acceptability test, the preference of ssanghwa flavoured sample, sample without flavour and a similar product in market was compared. There was no significant difference among three samples.

In this thesis we aim at analyzing international competitive power of Chinese ginseng in comparison with Korean ginseng and searching policy direction for Korea to compete Chinese ginseng industry. We summarized the research results as follows; First, we examine the structural change of ginseng industry of China. Second, we review the theories for international competitiveness and apply the method of analyzing competitiveness to ginseng industry. Third, we compared the international competitive power of the ginseng industry between China and Korea and found that Chinese ginseng, estimated by Revealed Comparative Advantage(RCA) at about 15, still remains high competitiveness in terms of cost and price but lowering price competitiveness recently. Based on the research results, we suggest export promotion strategies of the Korean ginseng as follows; 1) Korean government should enforce trade cooperation with China so as to register Korean root ginseng an importable medicine. 2) Korean ginseng producer should develop various products such as capsules, powders and etc. according to China's consumer purchasing power and taste. 3) Korean ginseng should be sold as an differentiated commodity so that it will contribute to building consumer loyalty to Korean ginseng, makes market share superior to other cheaper ginseng products in China. 4) In order to be effective brand marketing and product advertisement, there should be established reliable networks to process and distribute Korean ginseng products exclusively.

This study investigated the physicochemical properties of Pekin duck breast meat obtained from ducks fed diets consisting different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji during storage. A total of 180 Pekin ducks (0-day old) were divided into four groups, each consisting of three replicates (15 ducks per pen). This study investigated diets with four types of treatments: control (basal diet),1% blend powder, pelleted 1% blend, and coated pellets of 1% blend; the blend was a mixture of sipjeondaebo-tang by-products powder and red ginseng marc with fermented red koji. There was no significant difference (p>0.05) in duck breast meat pH on storage days 3 and 7, TBARS on storage days 0 through 7, and DPPH radical scavenging on storage days 0 and 7. However, the pH values on storage day 0 and DPPH radical scavenging on storage day 3 were significantly different (p<0.05) in the meats from control and treated diet fed ducks. Especially, on storage day 7, the breast meat from ducks treated with different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji showed lower TBARS values and increased DPPH radical scavenging activity compared to the control. In conclusion, addition of different types of sipjeondaebo-tang by-product and red ginseng marc with fermented red koji to 1% blend might be helpful in increasing antioxidant effects and reducing product wastage.

According to the results of my study on the chromatographic analysis of fresh ginseng (Panax ginseng C. A. Meyer) roots, most of the contents of protopanxadiol ginsenosides $Rb_1$, Rc, $Rb_2$, and Rd are derived from the corresponding malonyl ginsenosides in fresh ginseng by a heat process. Also, I confirmed that acetyl ginsenosides are naturally occurring constituents in fresh ginseng, not decarboxylates from malonyl ginsenosides. Seven neutral ginsenosides $Rg_1$, Re, Rf, Rc, $Rb_1$, $Rb_2$, and Rd were transformed to specific conversions in red ginseng preparation conditions. The conversion paths progress by three rules concluded from my study. These conversion rules are I: the ether bond is stable at positions 3 and 6 in the dammarane skeleton, II: the ether bond between sugars is stable in glycosides, and III: the ether bond to glycosides is unstable at position 20 in the dammarane skeleton.

The effects of red ginseng extracts (5.5 mg/mouse: i.p.) on the activities of antioxidant enzymes (superoxide dismutase, catalase and peroxidase) and lipid peroxidation were studied in the cytosol fraction of kidney. The experiments were carried out with whole-body irradiated (6.0 Gy, $^{60}Co$) and non-irradiated ICR mice. In the red ginseng extract-treated and irradiated mice, the activities of Cu, Zn- SOD, Mn-SOD, catalase and peroxidase were significantly enhanced by 27.8, 31.9, 17.9 and 15.0%, respectively, but the contents of malondialdehyde were considerably decreased (81.OfS) after 21 days, compared with those of non-treated mice. The enhanced activities of antioxidant enzymes inhibited the increase of malondialdehyde product resulted from the ionizing radiation. These results suggest that red ginseng extracts probably play an important role in radioprotective effect. Key words Red ginseng, SOD, catalase, peroxidase, lipid peroxidation.
