In order to develop convenient and reproducible methods for identification of ginseng drugs at a DNA level, RAPD (randomly amplified polymorphic DNA) and PCR-RFLP (PCR-Restriction fragment length polymorphism) analysis were applied within Panax species. To authenticate Panax ginseng betvyeen Chinese and Korean ginseng population, RAPD analysis were carried out using 20 mer-random primer. The similarity coefficients among the DNA of ginseng plants analyzed were low, ranging from 0.197 to 0.491. In addition, using PCR-RFLP analysis, very different fingerprints were obtained within Korean ginseng plants. These results suggest that these methods are able to authenticate the concerned Panax species. Broader application of this approach to authenticate other morphologically similar medicinal materials is rationalized.

Agmatine iminohydrolase (EC 3.5.3.12) catalyzes the hydrolysis of agmatine into putrescine. The enzyme seems to be one of the critical enzymes in putrescine biosynthesis. The enzyme was purified to homogeneity from Panax ginseng C.A. Meyer by combined method of ammonium sulfate 1 fractionation, DEAR anion exchange column, hydroxyapatite column and agmatine carboxyhexyl Sepharose 4B affinity column. The molecular weight estimated by native pore gadient polyacrylamide gel electrophoresis was 71, 000 Dalton, while that estimated by SDS-PAGE was 70, 000 Dalton, indicating a monomeric enzyme. The optimal pH and temperature were 9.0 and 37$^{\circ}C$, respectively. The Km and 1 Vmax for agmatine were 8.3 mM and 14.4 nmole/hr, respectively. Heat stability of this enzyme was high. The enzyme was observed to be inhibited by polyamines such as putrescine, cadaverine, spermidine and spermine. Especially, putrescine was a potent inhibitor of the purified enzyme. These results suggest that polyamines could be important in growth regulation of Panax ginseng C.A. Meyer.

In the browning reaction of Korean ginseng, it appears that enzymatic and non-enzymatic browning reaction occurred in the initial stage of heating fresh ginseng at low temperature, and then non-enzymatic browning reaction followed in the drying period after heating. Activation energy of the browning reaction for red ginseng was about 9.0 kcal/mol. Browning reaction of red ginseng was accede- rated with an increase in steaming time, and a great extent of browning reaction occurred between 60-90 min of steaming at 10$0^{\circ}C$. Browning pigments of red ginseng were mostly water soluble subset.

Hydrocortisone과 ginseng 그리고 hydrocortisone과 ginseng의 혼합물이 phytohaemagglutinin (PHA-P)으로 유도한 모세혈관 림파구 변형에 미치는 영향을 검토하기 위하여 정상인 4명을 대상으로 연구하였다. 인삼의 농도를 0.16${\mu}g$/ml에서 1.60${\mu}g$/ml까지 증가시킴에 따라 PHA-P의 림파구 변형에 상관성이 있는 억제현상을 보였으며, hydrocortisone 500${\mu}g$/ml과 ginseng 0.8${\mu}/g$/ml을 동시 투여하였을 경우 각각 단일 물질 투여시 보다 상당한 PHA-P 변형의 억제효과를 나타냈다. 이는 인삼이 in vitro상에서 steroid와 유사한 효과를 갖고 있음을 시사해 주며, 면역에 hydrocortisone과 더불어 상당한 효과를 가지고 있다는 것을 보여주고 있다. in vivo상에서 6명의 정상인을 대상으로 PHA-P 변형에 대하여 인삼의 효과를 연구한 결과 4주에 이르러 상당한 억제효과가 관찰되었다.

The common DNA extraction methods are indispensable for genotyping by molecular marker analysis. However, genotyping a large number of plants is painstaking. A modified 'NaOH-Tris' method used in this study reduces the extraction time while keeping the cost low and avoiding the use of hazardous chemicals. The endpoint analysis by realtime PCR tends to be fast and effective for the development of SNP markers linked to the 'Chunpoong' cultivar of Panax ginseng. The 'Chunpoong' marker was developed by a major latex-like protein gene sequence. From our results, we suggest that this method is successful in distinguishing 'Chunpoong' from a large number of ginseng cultivars.

교잡 1세대의 화서조직에서 재분화된 F1 유식물체는 고려인삼 유식물체에 비하여 지상부와 지하부 생육이 모두 양호하였으며, 줄기 색도 고려인삼 재분화 식물체의 줄기에 비하여 자색을 강하게 띄었으며 잎의 색도 진한 녹색을 나타내었다. 천풍, 연풍, 선원 등의 고려인삼의 품종 내에서는 Internal Transcribed Spacer (ITS)영역의 DNA PCR 패턴간에 차이점이 나타나지 않았으나, 고려인삼과 미국인삼은 각기 다른 PCR 패턴을 보였으며, 고려인삼과 미국인삼간의 교잡 1세대는 고려인삼과 미국인삼에 나타나는 고유한 PCR패턴을 모두 나타내었다. 교잡 1세대에서 유기한 캘러스와 재분화식물체는 조직배양 모본인 교잡 1세대와 동일한 PCR 패턴을 보임에 따라 교잡 1세대의 조직배양체는 ribosomal DNA의 ITS영역에서 유전적인 안정성을 나타내는 것으로 확인되었다.

Five years old ginseng plant (Panax ginseng) with ten stems from six bud base was found in a ginseng plantation. Stems were emerged even around the rhizome base. Growth status of all stems were poor. The length of some stems was shorter than that of petiole. The shorter the stem length is the longer the petiol length.

Ethylene was released from leaf and fruit but root of Panax ginseng. Root callus showed higher ethylene release (ER) than fruit ER increased with leaf senesence. Fruit during ripening showed decreasing ER in the order of green stage, early stage of reddening and fully ripened stage. between leaves from the plant with fruits in different stages of ripening showed similar trend of fruit in ER but it was about 10 times higher in leaves than in fruits. Leaves of P. quinquefolius showed about 200 times higher ER than that of P ginseng on 22 July Fruits from the plant treated with ethephon showed higher ER after 109 days. Forty-five day-old seedlings grown with various growth regulators showed a significant decrease of stem length and significant increase of ER only in Uniconazole (0.1 ppm) and H-9 (0.0, 5 ppm) solution.

Actoprotectors are preparations that increase the mental performance and enhance body stability against physical loads without increasing oxygen consumption. Actoprotectors are regarded as a subclass of adaptogens that hold a significant capacity to increase physical performance. The focus of this article is studying adaptogen herbs of genus Panax (P. ginseng in particular) and their capabilities as actoprotectors. Some animal experiments and human studies about actoprotective properties of genus Panax attest that P. ginseng (administered as an extract) significantly increased the physical and intellectual work capacities, and the data provided suggests that ginseng is a natural source of actoprotectors. Preparations of ginseng can be regarded as potential actoprotectors which give way to further research of its influence on physical and mental work capacity, endurance and restoration after exhaustive physical loads while compared with reference actoprotectors.

Ginseng, the root of the Panax ginseng, has been a popular and widely-used traditional herbal medicine in Korea, China, and Japan for thousands of years. Now it has become popular as a functional health food and is used globally as a natural medicine. Evidence is accumulating in the literature on the physiological and pharmacological effects of P. ginseng on neurodegenerative diseases. Possible ginseng- or ginsenosides-mediated neuroprotective mechanisms mainly involve maintaining homeostasis, and anti-inflammatory, anti-oxidant, anti-apoptotic, and immune-stimulatory activities. This review considers publications dealing with the various actions of P. ginseng that are indicative of possible neurotherapeutic efficacies in neurodegenerative diseases and neurological disorders such as Parkinson's disease, Alzheimer's disease, Huntington's disease, and amyotrophic lateral sclerosis and multiple sclerosis.
