The aim of this study was to compare the fermentation characteristics of tissue cultured mountain ginseng, extruded tissue cultured mountain ginseng, and root hair of red ginseng. Also, pH, acidity, brix, reducing sugar, total sugar, and alcohol were analyzed. The extrusion conditions were barrel temperature of 110 and $140^{\circ}C$ and moisture content of 25 and 35%. Fermentation temperature was $27^{\circ}C$ for 15 days and the cultivation was fixed with Saccharomyces cerevisiae, Aspergillus usamii, and Rhizopus japonicus. The results showed that pH, brix, reducing sugar content, and total sugar content of fermented broths were decreased after 5 days and then maintained steadily for the following 10 days. Acidity of final fermented broths were 1.12% (root hair of red ginseng), 1.19% (tissue cultured mountain ginseng), and $0.97{\sim}1.02%$ (extruded tissue cultured mountain ginseng), respectively. Alcohol content of final fermented broths were 3.82% (root hair of red ginseng), 0.91% (tissue cultured mountain ginseng), and $1.86{\sim}2.18%$ (extruded tissue cultured mountain ginseng). The fermentation efficiency of extruded tissue cultured mountain ginseng (barrel temperature $140^{\circ}C$, moisture content 25%) were the highest. In conclusion, the fermentation efficiency was increased by extrusion process.

We previously reported that in vitro anti-platelet activity of tissue-cultured mountain ginseng (TCMG) ethanol extracts show improved efficacy when compared with commercial ginseng products such as Korean red ginseng and Panax ginseng. However, information on the anti-platelet activity of the ethyl acetate fraction from TCMG adventitious roots is limited. Therefore, in this study, we further investigated the effects of an ethyl acetate extract of TCMG (EA-TCMG) adventitious roots on in vitro antiplatelet activity in whole human blood and its effect on peripheral blood flow in mice. We found that EA-TCMG inhibited platelet aggregation with $IC_{50}$ values of 271, 180, and 147 ${\mu}g$/mL induced by collagen, adenosine-5'-diphosphate, and arachidonic acid, respectively. Among the three agonists used, thromboxane $A_2$ formation induced by arachidonic acid was markedly suppressed. Furthermore, EA-TCMG improved the peripheral circulatory disturbance by improving vascular blood flow. In conclusion, these results suggest that ethyl acetate extracts from TCMG adventitious roots might inhibit vascular platelet aggregation and thrombus formation.

Present study investigated the effects of the 70% ethanol extracts of tissue-cultured mountain ginseng (TCMG), Korean red ginseng (KRG), and Panax ginseng (PG) on agonist-induced platelet aggregation and activation in human whole blood. The $IC_{50}$ values for TCMG, KRG, and PG were 1.159, 3.695, and 4.978mg/mL for collagen-induced aggregation, 0.820, 2.030, and 4.743mg/mL for arachidonic acid-induced aggregation, and 1.070, 2.617, and 2.954 mg/mL for ADP-induced aggregation, respectively. Also, this study assessed the effects of the most active extract, TCMG, on markers of platelet activation by determining receptor expression on platelet membranes in healthy subjects, including expression of GPIIb/IIIa-like (PAC-1) and P-selectin (CD62), by flow cytometry. A significant decrease in PAC-l expression (p=0.018) was observed in the presence of TCMG. These results show that TCMG has potent anti-platelet activity.

This study reviewed the application of an extract from mountain ginseng adventitious roots which had been grown through tissue culture as a cosmetic ingredient. The mountain ginseng adventitious roots were derived from mountain ginseng callus that was induced from mountain ginseng root whose origin is estimated to date back about one hundred years ago. The adventitious roots were separated from callus and grown in a 20 L bioreactor. In order to proliferate the adventitious roots, they were cultured for 5 weeks in bioreactor. Then the harvested mountain ginseng adventitious roots were dried and extracted. For verifying skin whitening effect of an extract from the tissue-cultured mountain ginseng adventitious roots in vivo, we performed the clinical test of it. The research showed the significant skin whitening effect of a mountain ginseng adventitious roots extract and the statistical analysis showed a significant difference (p<0.0001) between sample ($2\%$ mountain ginseng adventitious roots extract) and placebo. But, some saponins showed below $10\%$ inhibitory effect of tyrosinase and melanin synthesis in B-16 melanoma. The extracts of red ginseng and ginseng which were the same concentration as the tissue-cultured mountain ginseng adventitious roots extract's showed little inhibitory effect of tyrosinase and melanin synthesis in B-16 melanoma. In DPPH test, Anti-hydroxyl radical activity of $0.5\%$ the tissue-cultured mountain ginseng adventitious roots extract was $86\%.$.

Korean ginseng(Panax Ginseng C.A. Meyer) known as a oriental miracle drug is an important medicinal plant. Ginseng has been used for geriatric, tonic, stomachic, and aphrodisiac treatments for thousands years. Also, it is an antibiotic and has therapeutic properties against stress and cancer. Ginseng is widely distributed all over the world. Among them, Korean mountain ginseng has the most valuable effect on pharmaceuticals. The roots of mountain ginseng contained several kinds of ginsenosides that have many active functions for the human body. However, the study of mountain ginseng has a limit because the mountain ginseng is very expensive and rare. So, we artificially cultured mountain ginseng adventitious roots using the bioreactor culture system. We induced callus from original mountain ginseng, directly dug up in mountain and aged about one hundred ten years. Separated adventitious roots were precultured in 500ml conical flasks and then, transferred in 20L bioreactors. The adventitious roots of mountain ginseng were harvested after culturing for 40days, dried and then, extracted with several solvents. In this study, we investigated the whitening effect, anti-wrinkle effect and the safety of tissue cultured adventitious roots extract of mountain ginseng in order to identify the merit as a cosmetic ingredient. Particularly, extract of mountain ginseng adventitious roots showed whitening and anti-wrinkle effects. The inhibitory effect of this extract on the melanogenesis was examined using B-16 melanoma cell. When B-16 melanoma cells were cultured with adventitious root extract, there was a dramatically decrease in melanin contents of 8-16 melanoma cell. And we identified this extract inhibited Dopa auto-oxidation significantly. Also, when transformed mouse fibroblast L929 cells were treated with this extract, there was a significant increase in collagen synthesis. The results show significant inhibited melanization and wrinkle without inhibiting cell viability.

Ginseng root explants and calli were cultured on modified Murashine and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical compositon and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of ginseng calli, the concentrations of 2, 4-D and sucrose were in the range of 1 to 5 mg/l and 1 to 3%, respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magnesium, plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng.

In order to pursue some physiological studies on organogenesis in ginseng tissue culture, ginseng root explants were cultured on a modified MS medium containing NAA and kinetin. The activities of peroxidase and some enzymes were investigated and their isoenzyme patterns were also observed. The activity of peroxidase decreased by 20% in one week's culture and increased thereafter by 80% in culturing for 7 weeks compared with the control group. Glucose-6-phosphate dehydrogenase activity increased by 400% after culturing for 5 weeks and increased during the days preceeding root formation. The activities of glutamate dehydrogenase and acid phosphatase also increased during the culture. After 3 weeks' culture, new peroxidase isozyme (pH 7.6) appeared and 7 weeks' culture, another new peroxidase isozyme (pH unidentified) appeared. These patterns were also identified by using FPLC. After 7 weeks' culture, a new esterase isozyme of pH 8.5 appeared and isozyme patterns of acid phosphatase were quite changed compared with the isozyme patterns of tissue cultured for 5 weeks. In so far as these new isoenzymes appear distinctively after 7 weeks' culture, root differentiation is supposed to be induced after 7 weeks' culture.

The objective of this study is to compare the physicochemical properties and release characteristics of red ginseng (A) and tissue cultured mountain ginseng (B) extruded tissue cultured mountain ginsengs at barrel temperatures 110 (C) and $120^{\circ}C$ (D) to produce tissue cultured mountain ginseng-like comercial red ginseng by extrusion process. Extrusion process variables, water content and screw speed were fixed at 25% and 200 rpm, respectively. In the results, reducing and total sugar content were found to be relatively higher in A. The acidic polysaccharides content of B was the lowest among the ginseng samples. Acidic polysaccharide was increased 3 times by extrusion process. A and B were three times higher at maximum than C and D in polyphenolic compound. Polyphenolic compound content was relatively low by extrusion of ginsengs. Amino acid contents of B, C and D were $35{\sim}42\;{\mu}g/mL$; in contrast, A contained $25\;{\mu}g/mL$. The crude saponin content of C and D were higher than A and B.

In order to develop the biotechnological methods for the mass production of anticancer compounds from tissue culture of Panax ginseng C.A. Mayer, these studies were carried out for the selection of ginseng cell lines containing higher concentration of polyacetylene compounds and optimal condition for their biosynthesis. Panaxynol, one of ginseng polyacetylene, was not detected in any callus induced from ginseng superior cell lines cultured on MS medium supplemented with $\beta$-chlorophenoxy acetic acid (CPA). Panaxydol, another one of polyacetylene and anticancer compounds, were detected in calli of 5 cell lines by thin layer chromatogram and gas chromatogram. Among the 18 ginseng superior lines, the cell line 30201 has higher content of panaxydol. Especially, panaxydol was not detected in the callus induced from cell line 10301 which cultured on the medium containing CPA only, however, it was detected on the same callus cultured on mixed medium containing CAP 2 mg/L and BA 0.05 mg/L. SH medium was better than MS medium for ginseng callus growth and biosynthesis of polyacetylene, and also found that it was not effected by NAA and sucrose concentration in the culture medium.

This study was conducted to investigate the drying characteristics of tissue cultured mountain ginseng roots. The far infrared rays dryer of a double blast system used for this experiment can control the drying parameters such as far infrared heater temperature and air velocity. The far infrared rays drying tests of tissue cultured mountain ginseng roots were performed at air velocity of 0.4, 0.6, 0.8 m/s, under drying air temperature of 50, 60, and $70^{circ}C$, respectively. The results were compared with one obtained by the heated air drying method. The drying characteristics such as drying rate, color, energy consumption, saponin components and antioxidant activities were analyzed. The results showed that the drying rate of far infrared rays drying was faster than that of heated air drying and due to high temperature of drying air and fast air velocity, the far infrared rays drying of double blast type was superior to the heated air drying. The value of the color difference for heated air drying was 10.11${\sim}$12.99 and that of far infrared rays drying was in the range of 7.05${\sim}$7.54, which was in the same drying condition, also energy consumption of far infrared rays drying was in the range of 3575${\sim}$6898 kJ/kg-water. At the same time, the antioxidant activities using far infrared rays drying were higher than those using heated air drying.
