Ginseng root is an important remedy in oriental countries, which has been used for thousands of years. Saponins of ginseng root has been known to be the major component which mediate diverse pharmacological actions of the ginseng. Heat processing of ginseng root potentiates its biological activity such as anti-tumor and anti-oxidative activities. The butanol fraction of heat-processed ginseng (HGB) induced the production of nitric oxide in macrophages in a dose-dependent manner with IFN-${\gamma}$(30 U/ml) priming. The active component was identified as ginsenoside-$Rg_5$ from the activity-guided purification. Ginsenoside $Rg_5$ is one of major components of heat-processed ginseng and red ginseng that is responsible for the potentiated biological activities of processed ginseng. The induction of NO production by heat-processed ginseng might contribute to the potentiated biological activity of heat-processed ginseng.

The fermentation of Panax ginseng yields many compounds including ginsenosides that have various biological functions. The objective of this study was to investigate the modulation of nitric oxide (NO), Interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$ in Raw 264.7 cells treated with ginseng fermented by Penibacillus MBT213. Nitric oxide production in the Raw 264.7 cells treated for 24 hours with fermented ginseng at 3, 7, and 14 days after the treatment decreased to 74, 43, and 36%, respectively, compared with the positive control. The production of IL-6 was inhibited in all the cells treated with fermented ginseng at 3, 7, and 14 days after the treatment except for the positive control. The $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 6 hours at 3, 7, and 14 days after the treatment was about 40,000, 85,000 and 65,000 pg/mL, respectively. Moreover, the $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 24 hours at 7 and 14 days after the treatment was about 160,000 and 180,000 pg/mL, respectively. However, $TNF-{\alpha}$ production was inhibited in the Raw 264.7 cells at 6 and 12 hours after the treatment with fermented ginseng. herefore, it was confirmed that the immunological activity of the Raw 264.7 macrophages was affected by the treatment with fermented ginseng. It was concluded that ginseng fermented by Paenibacillus MBT213 possesses a potential anti-inflammatory activity and could be used as an ingredient in functional foods and pharmaceutical products.

This study presents a comparative study for differences in efficacy and ingredient of white ginseng(WG), red ginseng(RG), and black ginseng(BG) using anti-oxidative activity test and anti-inflammatory activity test. In the results of cytotoxicity test for WG, RG, and BG, the survival rate of all cells was more than 95%. In the total polyphenol analysis, DPPH, ABTS radical scavenging test, and ROS production test, BG showed higher anti-oxidant activity than WG and RG. RG and WG showed higher inhibition activity of NO production and $PGE_2$ production, respectively. As results of the test for the effect on reduction of inflammatory cytokine production, WG and RG were effective on reduction of IL-$1{\beta}$ production, and BG was effective on reduction of IL-6. In the case of TNF-${\alpha}$ production, there was no difference among samples. This study could be useful basic data for the development of functional food and the fabrication of safe cosmetic.

The effects of light on the growth and ginsenosides production were examined in the hairy roots of Panax ginsen C.A. Meyer induced by Agrobacterium rhizogines A4. The 9rowth of ginseng hairy roots in 1/2MS liquid medium was significantly decreased with an increment of light intensity (1,000~7,000 lux). The growth of hairy roots under 7,000 lux condition was decreased at 17% compared to the dark condition. The production of 7 ginsenosides in hairy root was very high in 3,500 lux condition. The production of ginsenoside-Rg, and Rf increased 3.3 and, 2.4 times respectively as compared to dark condition. The growth of hairy roots was inhibited by blue light, while ginsenosides production was increased. The sucrose demands of hairy roots was examined in light condition(3,500 lux). The growth of hairy roots in 1/2MS liquid medium with various sucrose concentrations(1~4%) was high in IVp sucrose, while ginsenosides production was high in 3% sucrose condition. The growth and ginsenosides production were high when hairy roots were cultured in dark condition for 1 week and then transferred to light condition(3,500 lux) for 4 weeks. It is suggested that ginsenosides production could be accelerated by light intensity of specific wavelength in cultures of ginseng hairy roots.

Panax ginseng root has been widely used as an important drug for thousands years in China, Korea and Japan. The main effective components of ginseng have been believed to be saponins. However, ginseng cultivation is very difficult and needs many years for growth. It has already been shown that Panax ginseng callus produces a considerable amount of the same kinds of saponins as in intact plants. Various culture conditions were examined for increased production of ginseng saponins by cell culture. The saponin contents and the growth rates in two cell lines of ginseng callus were compared in static and suspension cultures, rotary and reciprocal shaking cultures. It was shown that the growth rate in rotary shaking cultures of D5-B2K-B2K callus was the highest and ginseng saponin production was most effective in reciprocal cultures of D5-B2K-B2K callus. The saponin content per fresh weight of the culture was 1.03 times higher than that of the fresh ginseng root.

The seven traditional quality factors including age and root weight ect. were reviewed in relation to the chemical components as a new quality factor and pharmacological data. The other important factor, production place, appeared to be sum of the eight factors. The important of production place indicated that the best quality ginseng is produced in the optimum environment. The description of ginseng for medicinal use in present materia medica missed most traditional quality factors only indicating the change by processing. Such phenomena do not mean the significant of raw$.$ ginseng quality. since appropriate raw ginseng was supplied in traditional way. For the generation with analytical attitude the description of raw ginseng quality to the processed ginseng products is recommendable. For the quality control with biologically active or index compound, the composition of various compounds seems to be the best. The establishment of physical and chemical quality creteria that will match with the traditional mothod it needed and will accomplished by comparative research on raw ginseng from various production sites and growth conditions. The description of production-place, grade and quantity of raw ginseng to the processed products will give better information and higher popularity of products to consumers.

It was reported that Red ginseng contains specific ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$, which show various pharmacological effects. However, production of these specific ginsenosides from Red ginseng is not commercially applicable because of high cost of the raw material, roots. This work was carried out to examine the production of Red ginseng specific ginsenosides from Agrobacterium-transformed hairy roots. Hairy roots were induced from 3 year-old root segment of Korean ginseng (Panax ginseng C.A. Meyer) after infection with Agrobacterium rhizogenes A4. Among many lines of hairybroots, KGHR-8A was selected. Steam heat treatment of hairy roots was resulted in the changes of ginsenoside composition. Eleven ginsenosides were detected in heat-treated hairy roots but eight in freeze dried hairy roots. In heat treated hairy root, content of ginsenoside-Rb$_1$,Rb$_2$,Rc, Rd, Re, Rf, and Rg$_1$were decreased compared to those of freeze dried hairy roots. However, heat treatment strongly enhanced the amount of Red ginseng specific ginsenogides (ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$). Amounts of ginsenoside-Rg$_3$,-Rh$_1$and -Rh$_2$ in heat-treated hairy roots were 2.58, 3.62 and 1.08 mg/g dry wt, respectively, but these were detected as trace amount in hairy roots without heat treatment. Optimum condition of heat treatment for the production of Red ginseng specific ginsenoside was 2 h at 105$^{\circ}C$. This result represents that Red ginseng specific ginsenoside can be producted from hairy roots by steam heat treatment.

To evaluate the anticarcinogenic effect and its mechanism of red ginseng, the mice were treated with red ginseng and received subcutaneous Bl6 melanoma cell line injection on the back. Tumor incidence was same (100%) both in water and red ginseng-treated groups, but tumor production was delayed in red ginseng-treated group. Survival time was somewhat longer in red ginseng-treated group. The histopathological findings were similar in both groups, but lymphocytic infiltration around the tumor and melanin production in the tumor cells were prominent in the red ginseng-treated group. Flow cytometric analysis on T lymphocytes and natural killer cells revealed increased $T_H$/$T_S$ ratio and increased NK cells in red ginseng-treated group. These results suggest that the anticarcinogenic effect of red ginseng may be exerted by the increased cell-mediated immunity and natural killer cell activity.

North American ginseng production may have been maximized in the traditional growing areas in the last decade and further increases may be in woods grown root, for niche markets. The marketplace demands high quality roots. Most problems leading to low quality roots start with the grower and can be avoided. These include poor site selection, inadequate soil drainage, untimely and poorly applied pesticides, and neglect of good sanitary practices. Selection of low lying sites increased the plant damage from frost in Ontario in May 2002. Seeding is still the major method of propagation of ginseng in spite of some success in culturing different parts of the plant. Opportunities exist for shortening the stratification period of North American ginseng seed to allow spring planting. This may reduce disease incidence. Since only one-third of ginseng seed sown ultimately produces plants harvested after 3 years any approach that reduces disease incidence and improves seed germination, seedling emergence and crop stand must be pursued. Disease is the major problem in ginseng cutivation from seed stratification, soil preparation prior to planting, right through to drying of the roots. Replant disease remains as an unresolved problem and needs full characterization and new approaches for control. Much progress has been made in research and related extension activities in disease control although challenges will arise such as with Quintozene and its replacement with Quadris for control of diseases caused by Rhizoctonia. Decreased labor populations and increased associated costs for ginseng production are causing rapid mechanization in every aspect of the ginseng industry. Engineers, machinery dealers, and fabricators, and growers are being challenged to increase efficiency by mechanization.

Ginseng root explants and calli induced from selected cell lines were cultured on modified Murashige and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical composition and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of calli, the concentrations of 2, 4-D and sucrose were the range of 1 to 3 mg/${\ell}$l and 1 to $3\%,$ respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magmesian plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng. The patterns of ginsenosides, pharmacologically useful component, were different among the cell lines and contents of ginsenosides were much higher in selected cell lines than in original cell line.
