  • In this study, we investigated the appropriate conditions to extract acidic polysaccharide and to prepare red ginseng extract being rich in acidic polysaccharide from red tail ginseng marc produced after manufacturing alcoholic extract from red tail ginseng. Amount of acidic polysaccharide in red tail ginseng marc was about 11%. The best condition for the extraction of acidic polysaccharide from the marc was using of 3~5 mg of $\alpha$-amylase/g residue/15 ml of distilled water, and the amount of acidic polysaccharide in water extract of the residue treated with $\alpha$-amylase was about 27%. So, it is possible to manufacture red ginseng extract being rich in acidic polysaccharide using water extract of red tail ginseng alcoholic residue as extraction solvent. From the above results, we suggest that red tail ginseng residue produced by manufacturing alcoholic extract of red tail ginseng has high potencies in the utilization of waste material.

  • The effect of red ginseng ethanol extract on the immunotoxicity of diethylstilbestrol (DES) was studied in ICR mice. ICR male mice were divided into S groups (10 mice/group), and red ginseng ethanol extract (50, 100 and 200 mg/kg body wt., respectively) and DES (1 mg/kg body wt.) were injected intraperitoneally (i.p.) to ICR mice once a day for 2 weeks. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune response were evaluated by humoral immunity, cell-mediated immunity, non-specific immunity, and circulating leukocyte counts. The results of this study were summarized as followings: 1. The DES-treated control group as compared with normal group showed the tendency to decrease body weight rate and relative liver weight, decreased both humoral and cellular immune responses, phagocyte activity, and circulating leukocyte counts, but increased the natural killer (NK) cell activity. 2. Compared with the DES-treated control group, DES plus red ginseng ethanol extract-treated groups significantly decreased the body weight rate (P<0.01). Relative liver weight was significantly decreased in DES plus red ginseng ethanol extract (50mg/kg)-treated group (P<0.01), but significantly increased in DES plus red ginseng ethanol extract (100mg/kg)-treated group (P<0.01). Relative spleen and thymus weights were significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (200 mg/kg)-treated group (P<0.01). 3. Both humoral and cellular immune responses were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. 4. Phagocyte activity and circulating leukocyte counts were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. NK cell activity was significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (50 and 200 mg/kg)-treated groups (P<0.01).

  • This study investigated the effect of red ginseng extract on metastasis of colon cancer cells in vitro and in vivo. Wound healing migration, cell motility, invasion, and activity, protein expression, and mRNA expression of matrix metalloproteinases (MMPs) were examined in SW480 human colon cancer cells. SW480 cells were cultured with or without $100{\mu}g/L$ PMA in the absence or presence of various concentrations (100, 200, or $300{\mu}g/mL$) of red ginseng extract. Red ginseng extract treatment caused signifi cant suppression of cell motility and invasion (p<0.05) in SW480 cells. Red ginseng extract inhibited MMP-2 and MMP-9 activity and their protein and mRNA expression in a dose-dependent manner (p<0.05) in SW480 cells. For experimental metastasis, BALB/c mice were injected intravenously with CT-26 mouse colon cancer cells in the tail vein, and were orally administered various concentrations (0, 75, 150, or 300 mg/kg body weight) of red ginseng extract for 3 weeks. Numbers of pulmonary nodules were signifi cantly decreased in mice that were fed red ginseng extract (p<0.05). Plasma MMP-2 and MMP-9 activity signifi cantly decreased in response to treatment with red ginseng extract in mice (p<0.05). These data suggest that red ginseng extract may be useful for prevention of cancer invasion and metastasis through inhibition of MMP-2 and MMP-9 pathways.

  • This study was undertaken to investigate the effect of red ginseng extract (5.5 mg/mouse ip) on the activities of superoxide dismutase (SOD), peroxidase and catalase in the liver of the gamma ray irradiated male mice. The experimental groups consisted of control, red ginseng extract injection group, irradiation (8 $Gy^{60}$Co) group and red ginseng extract injection after irradiation group. in red ginseng extract injection group, SOD, peroxidase and catalase activities were similar to that in the control group. In irradiation group SOD, peroxidase and catalase activities increased progressively until the 2nd day after the treatment and then decreased thereafter, whereas red ginseng extract injection after irradiation group recovered more rapidly than irradiation group. The above results suggested that red ginseng extract injection after irradiation group have the recovery effects on the activities of SOD, peroxidase and catalase after radiation injury in the liver of male mice.

  • This study was carried out to isolate saponin compounds from red-ginseng efflux, which was produced during the industrial processing of red-ginseng from fresh ginseng. We isolated crude saponin from the efflux extract (moisture content 35.0%) by using Diaion HP-20 adsorption method. Non-saponin fraction, which was adsorbed on Diaion HP-20 resin, was removed by eluating with $H_{2}O$ and 25% spirit. Then crude saponin was eluated with 95% spirit, continuously. Saponin in the eluated fractions was confirmed by TLC analysis. Crude saponin isolated from red ginseng efflux extract contained 12.10% of saponin. whereas those of white ginseng and red-ginseng were 3.30 and 3.39%, respectively. Ginsenoside contents showed the highest contents kin crude saponin from red ginseng efflux extract. Expacilly, the ginsenoside-$Rb_{1}$ and Re showed the highest contents in red-ginseng efflux extract when compared with those of white ginseng and red ginseng crude saponins. And the other ginsenosides except ginsenoside-$Rb_{1}$ and -Re also showed the highest contents in red ginseng efflux extract. However, the ratio of PD saponin (Panaxadiol saponin: $Rb_{1}+Rb_{2}$+Rc+Rd) to PT saponin (panaxatriol: $Re+Rg_{1}$) showed almost the same level when compared with those of ginseng saponin fractions. Ratio of PD/PT from red ginseng efflux extract was 1.99. Ratios of PD/PT from white ginseng and red ginseng were 1.85 and 1.84, respectively. Saponin purity, which was calculated by ratio percent of total ginsenoside to curde saponin content, was 45.90%. In case of white ginseng and red ginseng, the purities were 35.50 and 36.00%, respectively. However, by PHLC analysis, we confirmed that crude saponin isolated from red ginsengs. It suggested that crude saponin isolated from red ginseng ellux also would be useful component as ginseng saponins.

  • Red ginseng extract was added to Yanggaeng to determine a practical use for the herb which has medical usage and functionality. We examined the antioxidant activity and quality characteristics of Yanggaeng prepared with different amounts (as ratios of 1%, 2%, 3% to the total materials) of red ginseng extract, as well as those of commercial red ginseng Yanggaeng. The antioxidant activity of the Yanggaengs samples was estimated by the DPPH free radical scavenging activity, $ABTS^{+\cdot}$ scavenging activity, and reducing power. The antioxidant activity of the Yanggaeng increased as a result of the addition of the red ginseng extract. Levels of polyphenol compounds and flavonoids increased according to the extract concentration. The quality characteristics of the red ginseng Yanggaeng were estimated in terms of pH, sugar content, viscosity, color, texture profile analysis, and sensory evaluations. With increasing concentrations of the extract, viscosity and sugar content increased, but pH decreased. In terms of the overall palatability, color, taste, flavor, and hardness, the 3% red ginseng Yanggaeng was determined as the best among the tested samples. Also, the 3% red ginseng Yanggaeng had higher scores than the commercial red ginseng Yanggaeng.

  • To develop a dry alcohol containing red ginseng extract, dry alcohols composed of ethanol, water, dextrin and sodium lauryl sulfate were prepared using spray dryer, and their ethanol contents and encapsulation efficiencies were determined. An optimal dry alcohol containing red ginseng extract was chosen and the feeling for its oral administration was evaluated. Dextrin at dextrin/water weight ratios below 1.6/l and ethanol at ethanol/water weight ratios below 1/1 remarkably Increased both the ethanol contents and encapsulation efficiencies of dry alcohols. However dextrin at dextrin/water weight ratios above 1.6/1 and ethanol at ethanol/water weight ratios above 1/1 slightly decreased the both parameters. It might be due to the low solubility of dextrin in ethanol and limited diffusion coefficient of ethanol to the dextrin shell. furthermore, 0.5% (w/w) sodium lauryl sulfate gave the maximum ethanol content of dry alcohol. The more increased amounts of red ginseng extract were added, the more increased amounts of ginsenoside Rb1 but the more decreased amounts of ethanol were encapsulated in dry alcohols. A dry alcohol containing red ginseng extract was prepared with dextrin/ethanol/water (1/1/1, w/w/w) mixed solution, in which 0.5% (w/w) sodium lauryl sulfate and 20% (w/w) red ginseng extract were dissolved. It contained the ethanol contents of31.17$\pm$ 1.33% (w/w) and ginsenoside Rbl of 243.0$\pm$7.0 $\mu$g/g. It gave the moderate taste of red ginseng extract at Its oral administration with or without water Thus, the dry alcohol containing red ginseng extract can be further developed as a more convenient dosage form for red ginseng extract.

  • This study was conducted to develop a healthy and functional drink using red ginseng, maekmoondong and omija using Saengmaeksan. Since the red ginseng extract was used as a raw material, it was diluted from 1,000 to 1,500 times using distilled water and the highest sensory score was obtained when the red ginseng extract was diluted to 1,500 times. When the red ginseng extract was mired with omija and maekmoondong, there was no difference between the ratio of 1: 20 : 1, 1 : 21 : 1 and 1: 22: 1 (red ginseng : omija : maekmoondong). In case of sweetener, honey showed the highest sensory store compared to sucrose, pear extract apple extract, sucralose and aspartame. Additionally, the sweetness was evaluated using all sweeteners and 10 brix or 11 brix showed the highest sensory score. Therefore, red ginseng extract was first mixed with omija and maekmoondong in the ratio of 1 : 20 : 1, and distilled water was added to 1,500 times of the amount of red ginseng extract. Honey was finally added to the mixture to obtain 10 brix concentration and this was highly acceptable.
