  • A radioprotective ginseng protein fraction was obtained from Korean white ginseng powder by the following isolation and purification procedures: Tris-HCI buffer extraction, 70% ammonium sulfate fractionation, CM-rellulosr column chromatography, heat inactivation and Sephadex G-75 column chromatography. This fraction was further purified by Sepharose 4B and Sephadex G-150 column chromatographies. Three fractions obtained were subjected to Native-PAGE and SDS-PAGE using gradient gels and the silver staining method. Molecular weights of the native proteins and their subunits were estimated.

  • Effect of ginseng hairy and native roots on body absorption, fecal and urinary excretion of Ingested radiostrontium were investigated in the mouse(NIH-strain, male) treated with or without pre-feeding of each ginseng soluble fraction. The test groups were fed with basic diet supplemented with 1% each ginseng soluble fraction for 7 darts before the radiostrontium were administered by intragastric intubation. In the groups of treated with soluble fraction from ginseng hairy roots, the radioactivities of fecal and urinary excretion increased about 15% over than that of control groups and the whole body retention were about 38%. In the groups of treated with soluble fraction from native ginseng roots, the radioactivities of fecal and urinary excretion increased about 25% over than that of control groups and the whole body retention were about 28%. Also, the levels of radiostrontium accumulation retained significantly the higher percent in skeletons than in other organs.

  • Trace metals in honey have an influence on the taste of honey along with pollens. Western bee honeys, which are mostly collected from acacia, have less than 0.1% of ash. Savor of Korean native-bee honey is thought to be due to the difference of the contents of trace metals. Korean native-bee honeys collected from Jirisan District, which is the greatest producing area of native-bee honey in Korea, showed high contents of ash. Korean native-bee honeys from the districts other than Jirisan District also showed similar results($0.44{\sim}0.83%$ of ash) to those from Jirisan District. Potassium was found to be the principal factor of high content of ash with over 85% of trace metals in ash.

  • Background: Korean ginseng (Panax ginseng Meyer) is a perennial herb prone to various root diseases, with Phytophthora cactorum being considered one of the most dreaded pathogens. P. cactorum causes foliar blight and root rot. Although chemical pesticides are available for disease control, attention has been shifted to viable, eco-friendly, and cost-effective biological means such as plant growth-promoting rhizobacteria (PGPR) for control of diseases. Methods: Native Bacillus amyloliquefaciens strain HK34 was isolated from wild ginseng and assessed as a biological control agent for ginseng. Leaves from plants treated with HK34 were analyzed for induced systemic resistance (ISR) against P. cactorum in square plate assay. Treated plants were verified for differential expression of defense-related marker genes using quantitative reverse transcription polymerase chain reaction. Results: A total of 78 native rhizosphere bacilli from wild P. ginseng were isolated. One of the root-associated bacteria identified as B. amyloliquefaciens strain HK34 effectively induced resistance against P. cactorum when applied as soil drench once (99.1% disease control) and as a priming treatment two times in the early stages (83.9% disease control). A similar result was observed in the leaf samples of plants under field conditions, where the percentage of disease control was 85.6%. Significant upregulation of the genes PgPR10, PgPR5, and PgCAT in the leaves of plants treated with HK34 was observed against P. cactorum compared with untreated controls and only pathogen-treated plants. Conclusion: The results of this study indicate HK34 as a potential biocontrol agent eliciting ISR in ginseng against P. cactorum.

  • Ginseng Is renowned for both its medicinal and herbal uses and successful cultivation of Panax ginseng in Asia and Panax quinquefolium in North America has until recently taken place in the native geographical ranges of the plants. As a consequence of the potential high capital return and anticipated increases in consumer consumption, commercial cultivation of American ginseng now occurs well outside the native range of the plant in North America. In fact, the region of greatest expansion of cultivation is in the semi-arid interior region of British Columbia, Canada. Linked with this expansion is the potential domination of the ginseng industry by agricultural corporations. In the interior of British Columbia, the native deciduous forest environment of eastern North America is simulated with elevated polypropylene shade and a surface covering of straw mulch. The architecture of these environments is designed to permit maximum machinery usage and to minimize labor requirements. Further, with only a four- years growth cycle, plant densities in the gardens are high. In this hot, semi-arid environment, producers believe they have a competitive advantage over other regions in North America because of the low precipitation rates. This helps to minimize atmospheric humidity such that the conditions for fungal disease development are reduced. If soil moisture level become limited, supplemental water can be provided by irrigation. The nature of the radiation and energy balance regimes of the shade and many environments promotes high soil moisture levels. Also, the modified environment redlines soil heating. This can result in an aerial environment for the plant that is stressful and a rooting zone environment that is suloptimal. The challenge of further refining the man modified environment for enhanced plant growth and health still remains. Keywords Panax ginseng, Panax quinquefolium, cultivation, ginseng production.

  • In this study, the major agronomic traits were investigated and RAPD technique was applied for the analysis of the genetic relations between the native ginsengs collected from Poonggi and Geumsan provinces in Korea. The main morphological traits were measured for a total of 54 collections of native ginseng from two areas based on UPOV standard. A total of 58 collections consisting of twenty-one native ginsengs collections from Poonggi area, twenty-nine collections from Geumsan area and four varieties of P. quinquefolium, P. japonicum, Chunpoong and Hwangsuk as controls were analyzed and clustered by RAPD. The results indicated that 01-9, 01-35 and 01-44 collections from Poonggi area were grouped into Geumsan area, while 332001, 332002 and 332003 collections from Geumsan area were grouped into Poonggi area. On comparison to the similarity of Poonggi collections (73-95%), the Geumsan collections showed 65-86% similarity in the population. Thus, the cluster should be applied according to the number of stem, number of leaves per stem and leaflet shape on the regionally native ginseng collections. The fourteen primers such as OPA02, OPA07, OPC08, OPD11, OPD20 and so on, will be used to select the native ginseng in the future studies.

  • The major protein (GMP) from the roots of Panax ginseng C. A. Meyer was purified, using gel filtration and ion exchange chromatography followed by reversed-phase and ion exchange FPLC. Staining analysis indicated that the protein has a carbohydrate moiety, which was also shown by band shift experiments using various glycosidases. Electrophoretic and gel permeation studies showed that GMP has an apparent molecular weight of 63 kDa composed of possibly two subunits of 25 kDa containing carbohydrate moiety. GMP showed an anticomplementary activity on the hemolysis of red blood cells, which is a screening tool for inflammation mediator search.

  • In this study, a total of 25 lines consisting of five native ginseng collections from Poonggi area, five lines from Geumsam area and 15 varieties were analyzed and clustered for the selection of Poonggi native ginseng in Korea using DNA markers. The results indicated that the long cluster distance were observed between the collections of 331002, 331004, 331005, 331007 and 331026 from Poonggi area, and the collections of 332009, 332021, 332046, 332050 and 332066 from Geumsan area because of the sensible differences on the number of leaves per stem, stem color and petiole color. Thus, the collections from Poonggi area with specific characters consisting of one stem per plant, five leaves per stem and broad elliptic leaflet shape were finely classified using nine primers including OPD05, OPD20, OPG17, OPH05 and so on. In this study, the collection of 331007 from Poonggi area was considered as the respective collection with above characters. Thus, the nine primers such as OPD05 and so on, will be used to select the Poonggi ginseng in the future studies.
