In order to establish effective extracting method of ginseng extracts from fresh ginseng, the yield, chemical composition, physical properties and organoleptic quality of the extracts, which are extracted with various concentrations of ethanol, were investigated. The results are as follows : 1. The yield of the extracts was increased with decreasing the concentration of ethanol as solvent. As in case of water as a solvents, the highest yield was achieved when 23.64% of water was used. The yield were 12.3% and 9.05%, when 70% and 90% of ethanol were used, respectively lively. 2. Crude protein content is the highest level and nitrogen·free extracts content is the lowest at the concentration of 50% ethanol. Lipid was increased linerly while ash was decreased as increment of ethanol concentration. 3. Viscosity and residue of the extracts also decreased in accordance with the increament of ethanol concentration and the transmittance value and pH of extract solutions were almost similar except transmittance value of the water extracts. 4. The extracts extracted with 70% ethanol gave the best result of sensory test. The total sensory test score of each extracts (70%, 90%, 50%, 0% and 30%) were 70, 65, 50, 46 and 41, respectively.

The purpose of this study is to investigate whether the intracellular hydrogen peroxide productions of mouse macrophage RAW 264.7 are modulated by Red Ginseng-Ejung-tang water extract (ER) and White Ginseng-Ejung-tang water extract (EG). Red Ginseng-Ejung-tang were composed of Red Ginseng, Atractylodes rhizome white, Zingiberis Rhizoma Siccus, and Glycyrrhizae Radix. White Ginseng-Ejung-tang were composed of White Ginseng, Atractylodes rhizome white, Zingiberis Rhizoma Siccus, and Glycyrrhizae Radix. The intracellular hydrogen peroxide productions were measured by dihydrorhodamine 123 assay with spectrofluorometer (excitation 485 nm; emission 535 nm). For 4, 20, 24, 44, 48, 68, and 72 h incubation, ER significantly increased hydrogen peroxide productions of RAW 264.7 at the concentration of 25, 50, 100, and $200{\mu}g/mL$ (P <0.05). EG for 4, 20, 24, 44, and 48 h incubation significantly increased hydrogen peroxide productions of RAW 264.7 at the concentration of 25, 50, 100, and $200{\mu}g/mL$ (P <0.05). For 68 and 72 h incubation, EG at the concentration of 50, 100, and $200{\mu}g/mL$ significantly increased hydrogen peroxide productions in RAW 264.7 (P <0.05). These results suggest that ER and EG have the immune-enhancing properties related with their increasing effects on the intracellular hydrogen peroxide production of macrophage.

For the current study, 2,000 questionnaire sheets were printed and distributed while at the same time postal questionnaires were also conducted. The questionnaire survey was conducted July 25 through September 25, 2008, whereby 206 copies of desirable responses were secured. Analysis of the survey made it possible to grasp the overall current status and prospects of the mountain-grown ginseng business, and the level of technology required for cultivating mountaingrown ginsengs. It was learned that, with no legal and institutional arrangements now in force, no precise facts and figures concerning the total area cultivated and the quantity produced are currently available, and that the products are being marketed under the table. Under such circumstances, it is high time for the mountain-grown ginseng cultivation business to contribute to the promotion of incomes of the farming households and the generation of national wealth by developing the business into a systematic industry. This study conducted a survey on the current status of mountain-grown ginseng producers and of their production, thereby contributing to the introduction of policies for mountain-grown ginsengs.

각 체질별(태음인, 소양인, 소음인)로 5명씩 혈액을 채취하여 임파구를 분리한 후 백삼 및 홍삼 에탄을 추출물을 투여하여 면역효능(proliferation, NO생성 및 TNF-$\alpha$의 분비능)을 측정한 결과, 한방에서 음인을 보하는 약재로 알려진 백삼의 경우 소음인 군의 임파구에서 가장 높은 임파구 증식능, NO 생성 및 TNF-$\alpha$의 분비능을 나타냈으나, 소양인군에서는 가장 낮은 면역활성을 나타내었다(P<0.05). 그러나 홍삼 추출물의 경우 각 체질군에서 면역활성의 차이가 없이 유사한 것으로 나타났다(P > 0.05). 또한, 체질별 임파구에 LPS처리한 대조군보다 백삼 및 홍삼 추출물을 첨가한 처리군에서 NO생성 및 TNF-$\alpha$의 분비능이 현저하게 높은 것으로 나타났다(P<0.05).백삼과 달리 홍삼 추출물에서 각 체질군에 면역활성의 차이가 없는 것은 인삼의 가공처리 과정에서 성분변화의 차이에 기인하는 것으로 사료된다. 따라서 본 연구 결과, 홍삼추출물로부터 체질에 영향을 미치지 않는 성분을 규명한다면 새로운 맞춤형 체질마커로 개발할 수 있으리라 사료된다.

Background: It has been known that ginseng can be applied as a potential nutraceutical for memory impairment; however, experiments with animals of old age are few. Methods: To determine the memory enhancing effect of red ginseng, C57BL/6 mice (21 mo old) were given experimental diet pellets containing 0.12% red ginseng extract (approximately 200 mg/kg/d) for 3 mo. Young and old mice (4 mo and 21 mo old, respectively) were used as the control group. The effect of red ginseng, which ameliorated memory impairment in aged mice, was quantified using Y-maze test, novel objective test, and Morris water maze. Red ginseng ameliorated age-related declines in learning and memory in older mice. In addition, red ginseng's effect on the induction of inducible nitric oxide synthase and proinflammatory cytokines was investigated in the hippocampus of aged mice. Results: Red ginseng treatment suppressed the production of age-processed inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-${\alpha}$, and interleukin-$1{\beta}$ expressions. Moreover, it was observed that red ginseng had an antioxidative effect on aged mice. The suppressed glutathione level in aged mice was restored with red ginseng treatment. The antioxidative-related enzymes Nrf2 and HO-1 were increased with red ginseng treatment. Conclusion: The results revealed that when red ginseng is administered over long periods, age-related decline of learning and memory is ameliorated through anti-inflammatory activity.

The quality of raw, red and white ginseng and the contents of some minerals were examined using 6-year-old ginseng roots produced in different shades, thatch and polyethylene net (P..E.). The yield of first and second grade ginseng roots was higher in the thatch shade than in the P.E. shade. The smaller sizes of ginseng routs were probably due to loss of ginseng yield called by alternaria blight in the third and fourth years, and lower quality was dale to more rusty roots in the P.E. shading. For red ginseng. rates of heaven and earth grades were higher in the P.E. than thatch shade. producing red ginseng with less inside cavity Production of white ginseng was higher in the thatch shade than in the P.E. shade. showing a higher yield, better piece grade, lower inside crack and better quality index in the thatch. The contents of some minerals such as K, Ca, Mg and Mn of fine ginseng roots differed between the two shades, some of which had a significant correlation with the quality indices of white ginseng. Keywords Thatch shade, polyethylene shade, alternaria blight, rulsty root, quality of ginseng.

The adventitious root of Panax ginseng C.A. Meyer is regarded as an efficient alternative to cell culture or hairy root culture for biomass production due to its fast growth and stable metabolite production. To determine optimal culture conditions for the bioreactor culture of ginseng roots, experiments have been conducted on physical and chemical factors such as bioreactor type, dissolved oxygen, gas supply, aeration, medium type, macro- and micro-elements, medium supplement during culture period, sucrose concentration, osmotic agents, medium pH and light. Elicitation is a key step to increase ginsenoside accumulation in the adventitious roots but biomass growth is severely inhibited by elicitor treatment. To obtain high ginsenoside content with avoiding biomass decrease, we applied two-stage bioreactor culture system. Ginseng adventitious roots were cultured for 40 days to maximize biomass increase followed by elicitation for 7 days to enhance ginsenoside accumulation. We also experimented on types and concentrations of jasmonate to determine optimal elicitation methods. In this paper, we discussed several factors affecting the root propagation and ginsenoside accumulation. Based on the results obtained from previous experiments we have established large-scale bioreactor system (1 ton-10 ton) for the efficient production of ginseng adventitious roots and bioactive compounds including ginsenoside. Still, experiments are on going in our laboratory to determine other bioactive compounds having effects on diet, high blood pressure, DPPH elimination and increasing memories.

This study was conducted to obtain basic information about the transformation of ginseng tissue, identification of opine compound and protein, and saponin production from ginseng callus transformed with Ti-plasmic of AW$.$obacterium tumefaiens C58. Ginseng crown gall callus induced by pTiC58 could be continuously cultured on the Phytohormone-free medium. The transformation was reconfirmed by the detection and identification of opine compound, from the gall callus. The transformed ginseng callus contained higher amounts of protein than normal callus and the protein pattern of transformed callus was quite different from that of normal callus. The xylose which is not detected in the normal callus and ginseng root was identified in gall callus. The saponin contents of gall callus of ginseng were three times higher than that of normal callus, and ginsenoside composition of the transformed callus was similar to that of the cultivated ginseng root, but quite different from that of normal callus.
