  • When extracts of KMG (Korean mountain ginseng) leaf tea and fermented KMG leaf tea were compared, the fermented KMG leaf tea extract showedhigher activity at each stage of density. Among the material groups, the KMG extract hadthe least profound SOD-like activity, and similar SOD-like activities were noted in the fermented KMG, KMG leaf tea, and fermented KMG leaf tea extracts. With regard to nitrite scavenging ability at a pH of 1.2, the KMG, fermented KMG, and KMG leaf tea groups exhibited similar results, and at pH 3.0, the KMG and KMG leaf tea extract groups exhibited more profound nitrite scavenging ability compared to the fermented groups. In the case of HeLa cell treatments, the KMG and fermented KMG leaf tea extracts exhibited cancer cell propagation restraint rates in excess of 30%, at a density of 1 mg/mL. And MCF-7 cells treated with fermented KMG and KMG leaf tea showedsimilar propagation restraint rates at more than 27% of cancer cells, at a density of 1 mg/mL. Among the materials, the KMG extract hadthe lowest cancer cell propagation restraint rate at 21%, and the fermented KMG leaf tea extract had the highest rate at more than 70%.

  • This study was carried out to provide basic information for standard cultivation guideline of Korean mountain cultivated ginseng (Panax ginseng). Environmental conditions, soil properties, growth process, cultivation methods and sowing timing were investigated in cultivations of Korean mountain cultivated ginseng in Korea (18 region in 9 province). Most of Korean mountain cultivated ginseng was cultivated to north, north-east, east or north-west direction in broad-leaved forest, IV age group, and 500~1,000 trees/ha. Elevation was below 500 m and slope was below $25^{\circ}$ in cultivation. There were significant differences in soil properties by region and cultivation based on organic matter (3.43~24.07%) and pH level (3.8~5.7). Sprouting, leaf unfolding, flowering, fruiting, red ripening, fruit drop and leaf drop of Korean mountain cultivated ginseng was investigated in cultivation. The results show that it took 98 days on average for the whole growth process. There were two methods, sowing and transplant for cultivation. Sowing methods were classified in sowing after opening-testa treatment and direct sowing. and it was 70% and 30%, respectively.

  • ISSR PCR technique was applied to investigate genetic relationship among 5 Mountain cultivated ginseng populations (Jinan, Hongcheon, Punggi, Andong and Yeongju) and cDNA libraries of wild ginseng roots were constructed and analyzed functional genes related to morphogenesis via EST. Twenty four ISSR markers tested produced 127 polymorphic loci from 5 regional Mountain cultivated ginseng. Among the regional samples, Yeongju was made 18 polymorphic loci that were the highest level of variations among the cultivated regions. The range of similarity coefficient was 0.46~0.58 and the regional samples of Punggi and Hongcheon, Jinan and Andong were classified to similar groups respectively, whereas Yeongju was shown to be separate group with high level of genetic variation in UPGMA cluster analysis. As a result, there was no relationship according to geographical distance and genetic similarity. Eleven cDNA clones were consisted of 9 known genes and 2 unknown genes analyzed by BLAST program of NCBI. To recognize expression pattern of Homeodomain transcription factor related genes, Northern Blot analysis was performed for wild ginseng's leaf and root. As a result, the gene was only expressed by Mountain wild ginseng root.

  • This study was conducted to investigate extracting solution effect on the chemical compositions in different parts of Korean mountain Ginseng. Water, 80% EtOH and 80% MeOH are used as extraction solutions, and extracting conditions were 2 hr at $85^{\circ}C$ in water bath. The Brix(%) of the extract were ranged from $0.42{\sim}22.58%$, 80% EtOH extract for leaf is the highest level as 22.58%. The pH ranges of the extracts were $4.43{\sim}7.41$ and brown color of the extract was the highest with 1.803 in 80% EtOH extract for leaf, respectively. In case of hunter's color value of the extract, L value is the highest with 24.35 in 80% EtOH extract of seed, a and b value were the highest with 0.41 in 100% water extract of leaf and 3.69 in 80% MeOH extract of stem. Sucrose is the major free sugar of the extinct it highest content with 3673 mg% in 80% MeOH extract of mot and fructose is the highest with 1897 mg% in 80% MeOH extract of leaf, Major organic acids are identified as malic, tartaric and citric acid, and total organic acid content is the highest with 5,254 mg% in 80% MeOH extract of leaf and 1,527 mg% in 80% EtOH extract of leaf, The extracted major minerals ate P and K, P content highest with 15,563 ppm in 100% water extract of stem, K is 4,952 ppm in 80% MeOH extract of leaf, and Ca is the highest with 3,052 ppm in 1011% water extract of leaf. These results suggest that extracting solvent (80% MeOH) is concerned with the extract preparation of Korea Mountain Ginseng.

  • This study was conducted to investigate antioxidant activity and functional component analysis in different sections of Korean mountain ginseng (seed, leaf, stem and root). The major free amino acids were arginine, proline, $\gamma-amino-n-butyric$ acid, alanine and aspartic acid, and proline showed the highest content 22.98 mg/g in 80% MeOH extract of seed. Contents of $\gamma-amino-n-butyric$ acid and alanine were the highest in 80% MeOH extract of leaf, with 26.04 mg/g and 13.07 mg/g. Aspartic acid showed the highest content 23.42 mg/g in 80% MeOH extract of leaf. The major fatty acids were identified as palmitic acid, oleic acid and linoleic acid by GC. Content of total phenolic compounds were 737 mg% in 80% EtOH extract of seed, and 560 mg% in 80% MeOH extract of seed. The highest contents of ferulic acid and salicylic acid were $875{\mu}g/g\;and\;78{\mu}g/g$ in 80% MeOH extract of leaf, and $\rho-coumaric$ acid was $181{\mu}g/g$ in 80% MeOH extract of stem, respectively. The highest contents of ginsenoside-Rg1, Re, Rd and Rc were $14.5{\mu}g/g,\;48.78{\mu}g/g,\;27.57{\mu}g/g\;and\;4.87{\mu}g/g$ in 80% MeOH extract of leaf, respectively. Antioxidant activities by DPPH were 83.82% in water extract of leaf, 89.74% in 80% EtOH extract of leaf and 88.37% in 80% MeOH extract of leaf, and 92.81% in BHA (200 ppm). These results suggest that Korean mountain ginseng is very important as functional food material.
