  • This study was carried out to compare the root yields, root characters, saponin and ginsenosides contents of 6-year-old p. ginseng and p. quinquefolium. These two ginseng species showed difference in the diameter and ten비h of mainroot. The main root length or p. quinquefolium was shorter than that of p. ginseng, whereas Jakyung-jong and Hwangsook-jong of P. ginseng showed similar root length. Proximate composition were similar between the two species, however, crude fibercontent was significantly higher in main and lateral root of Jakyung-jong and Hwang sook-jong of P ginseng than P quinquefolium. In regard to mineral contents of root, P ginseng contained more Ca and Mn and less Fe and Al than P. quinquefolium. P. quinquefolium contained more of Rbl and Rd of protopanaxadiol saponin, and less or Re, $Rg_1$ and $Rg_2$ of protopanaxatriol saponin than P ginseng. However, no Rf was detected in the p. quinquefolium. Key words Panax ginseng, Panax quinquefolium, ginseng character, ginsenoside.

  • Chemical components of Panax (P) species were compared. p. species used were Korean white ginseng, Korean, Chinese and Japanese red ginseng (P ginseng), American and Canadian ginseng (P. quinquefolium) , and sanchl ginseng (P. notoginseng). No significant difference in the proximate contents was observed among P. species. Ash, crude lipld and total sugar contents in root of P. notoginseng were found to be relatively lower than those of P. ginseng and P. quinquefolium, but the contents of crude protein and crude fiber were similar among those ginsengs. Mineral nutrient con tents showed a little difference among ginseng species. Total nitrogen contents were slightly higher in P. ginseng than P. quinquefolium and P. notoginseng and Fe and Cu were lower in Chinese and Japanese red ginsengs. Kinds and compositions of amino acids were similar but contents of amino acids were different among ginseng species. Total amino acid contents were 76.3∼83.9 mg/g in P. ginseng 53.8∼60.4 mg/g in p. quinquefolium and 54.9 mg/g in P notoginseng. Free sugar contents were lower in P. notoginseng than P. ginseng or P. quinquefolium. Sucrose accounted for 90∼92% of total free sugar contents with relatively high content in white ginsengs, while sucrose and maltose were 32-36% and 55∼60%, respectively, in red ginseng.

  • The strains of Panax ginseng C.A. Mey., P. quinquefolius L. and selected strains P. ginseng-B, P.ginseng-A, P. quinquefolius-C were investigated. Activities of SOD, catalase and peroxydase were determined by methods of Fridovich et al. (1979), Komov et al.(1975), Bovaird et al.(1982) respectively. Activities of SOD, catalase, peroxydase were investigated every day 5 in cycle of cultivation. For P. ginseng it was the 35 days, P. quinquefolius the 70 days, P. quinquefolius-C 90 days. P. ginseng-B 90 days, P. ginseng-A 60 days. The P. quinquefolius, P. quinquefolius-C, P. ginseng-B had clear differentiation and developed tracheid elements, which are absent in strain of P. ginseng. The peaks of protein content for P. ginseng (4.5 units/g) and for P. quinquefolius (3.5 units/g) were on day 10 and remained unchanged till the last cultivation. The strain P. ginseng-A had two peaks of protein content (2.5 mg/g) on day 15 and on day 30. For P. ginseng-B strain these peaks were on day 5 and day 40 (3.5 mg/g). Peroxydase activity peak (60 units/g) in P. ginseng strain was on day 10. This activity in P. ginseng-B had two peaks on day 15 and day 35 and reached 95 units/g , increasing to 150 units/g to day 80. In strain of P. ginseng-A was only one maximum of this activity -130 units/g on day 45. In P. quinquefolius peroxydase activity was 103 units/g on day 40, increasing to 135 units/g to day 90. For P. quinquefolius-C this activity peak was 136 units/g on day 60. Peroxydase activities for the upper and lower layers of biomass was different and varied considerably from 28-35 units/g in lower to 270-290 units/g for upper layer. The SOD activity had two peaks in P. ginseng strain the 80 units/g and the 70 units/g on day 20 and day 35 respectively. Activity of SOD in P. quinquefolius strain reached 53 units/g on day 40 and increased up to 83 units/g to day 60.The similar increase of SOD activity was marked for P. ginseng-B to 85 units/g on day 90. In P. ginseng strain the 6 molecular isoforms SOD was defined. One of them with RfO,6 was determined in all days of cycle, three other (Rf-0.43; 0.54;0.80) only on day 10 and day 20. The isoform of SOD with Rf-0,29 was detected only on day 10 and with Rf-0,35 only on day 35. The catalase activity decreased in all strains to the last days of cultivation. The changes of SOD, catalase and peroxydase activities reflect the differences between the strains of Panax ginseng and Panax quinquefolius and their selected forms. The correlation between maximum life span of strains and activities of their antioxydant enzymes were detected.

  • The content and composition of saponin compounds of Panax species were analyzed according to their species, region and processing type of red and white ginseng. The species employed were Korean-, Chinese-, Japanese red ginsengs, and Korean white ginseng of Panax ginseng, American- and Canadian ginsengs of Panax quinquefolium, and Panax notoinseng. Twelve main saponin components in the ginseng were identified and quantified using TLC and HPLC. All three species had remarkably different content and composition. However, within each species they were similar. Twelve major ginsenosides were determined in P. ginseng, eight in p. quinquefolium, and six in P. notoginseng. Of the components of P ginseng Rf, $Rh_1$, $Rh_2$ and Ra were not detected in P quinquefolium, and $Rb_2$, Rc, Rf, $Rh_2$, Ra and Ro not detected in P. notoinseam. Crude saponin content and protopanaxadiol/protopanaxatriol saponin ratio were compared. They were 4.81~5.24% and 1.27~ 1.45 in p. ginsengs, 7.01~7.25% and 2.12~ 2.15 in p. quinquefolium, 9.80% and 0.99 in P. notoineng. The prosapogenin and sapogenin content were different among the Panax species.

  • This study was carried out to determine the differences of essential oil components among Korean, Chinese and Japanese red ginseng, and Korean white ginseng (Panax ginseng C.A Mayer) , American and Canadian ginseng (P. Quinquefolium), and sanchi ginseng (P notoginseng). The steam distilled oils of these ginsengs were analyzed by GC and GC-MS, and 22 sesquiterpenes, 8 sesquiterpene alcohols, 8 monoterpenes, 5 aldehydes, 4 esters, 3 acids, 2 alcohols and 5 miscellaneous components were identified. The major oil components of Korean, Chinese and Japanese red ginseng were $\beta$-panasinsene, $\beta$-caryophyllene, $\alpha$-panasinsene, $\alpha$-neoclovene, selina-4,11-diane, bicyclo-ger-macrene and spathulenol. The contents of $\beta$-panasinsene, $\alpha$-neoclovene, $\alpha$-basabolene and spathulenol were higher in Korean red ginseng than Chinese and Japanese red ginseng. The contents of $\alpha$-cubebene, selina-4,11-diene and ledol were higher in Chinese red ginseng than Korean and Japanese red ginseng, but those of selina-4,11-diene and spathulenol were lower in Japanese red ginseng than Korean or Chinese red ginseng. On the other hand, the GC patterns of the oils from American, Canadian and sanchi ginseng were different from that of Korean white ginseng.

  • Background: Amino acids are one of the major constituents in Panax ginseng, including neutral amino acid, acidic amino acid, and basic amino acid. However, whether these amino acids play a role in ginsenoside conversion during the steaming process has not yet been elucidated. Methods: In the present study, to elucidate the role of amino acids in ginsenoside transformation from fresh ginseng to red ginseng, an amino acids impregnation pretreatment was applied during the steaming process at 120℃. Acidic glutamic acid and basic arginine were used for the acid impregnation treatment during the root steaming. The ginsenosides contents, pH, browning intensity, and free amino acids contents in untreated and amino acid-treated P. ginseng samples were determined. Results: After 2 h of steaming, the concentration of less polar ginsenosides in glutamic acid-treated P. ginseng was significantly higher than that in untreated P. ginseng during the steaming process. However, the less polar ginsenosides in arginine-treated P. ginseng increased slightly. Meanwhile, free amino acids contents in fresh P. ginseng, glutamic acid-treated P. ginseng, and arginine-treated P. ginseng significantly decreased during steaming from 0 to 2h. The pH also decreased in P. ginseng samples at high temperatures. The pH decrease in red ginseng was closely related to the decrease in basic amino acids levels during the steaming process. Conclusion: Amino acids can remarkably affect the acidity of P. ginseng sample by altering the pH value. They were the main influential factors for the ginsenoside transformation. These results are useful in elucidating why and how steaming induces the structural change of ginsenoside inP. ginseng and also provides an effective and green approach to regulate the ginsenoside conversion using amino acids during the steaming process.

  • 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 was conducted to elucidate the effects of light intensity using polyethylene (p.E) net shading on the specific gravity, red ginseng quality, sugar and saponin contents of ginseng root. The specific gravity significantly increased in the ginseng roots grown under the P.E net shading as compared with that of common straw shading. The red ginseng quality under the P.E net shading was improved in order of 10, 5, 15, 20, 30% of light intensity and the inside cavity and inside white part decreased remarkably as compared with those of common straw shading. The ginseng roots grown under the P.E net shading at 10% and 15% light intensity showed a significant increase in the total sugar content but a significant decrease in the reducing sugar content at 15% light intensity as compared with those of common straw shading. The amount of total saponin of ginseng roots was increased under the P.E net shading at high light intensity as compared with that of common straw shading and the ginseng roots grown under the P.E net shading at 10% light intensity showed an increase in the diol group saponin but the ratio of PT/PD was decreased. Extract contents of ginseng root under the P.E net shading was higher than those of common straw shading and the roots grown under the P.E net shading at 15% and 20% light intensity resulted in a remarkable increase in extract contents.

  • The quality of raw, red and white ginseng and the contents of some minerals were examined using 6-year-old ginseng roots produced in different shades, thatch and polyethylene net (P..E.). The yield of first and second grade ginseng roots was higher in the thatch shade than in the P.E. shade. The smaller sizes of ginseng routs were probably due to loss of ginseng yield called by alternaria blight in the third and fourth years, and lower quality was dale to more rusty roots in the P.E. shading. For red ginseng. rates of heaven and earth grades were higher in the P.E. than thatch shade. producing red ginseng with less inside cavity Production of white ginseng was higher in the thatch shade than in the P.E. shade. showing a higher yield, better piece grade, lower inside crack and better quality index in the thatch. The contents of some minerals such as K, Ca, Mg and Mn of fine ginseng roots differed between the two shades, some of which had a significant correlation with the quality indices of white ginseng. Keywords Thatch shade, polyethylene shade, alternaria blight, rulsty root, quality of ginseng.

  • Panax ginseng Meyer (P. ginseng; Korean ginseng) is well known for its medicinal properties. It can alleviate pathological symptoms, promote health, and prevent potential diseases via its anti-inflammatory, antioxidant, homeostatic, and other positive effects on biological metabolism. Although many studies have determined effects of P. ginseng on various diseases, such as cardiovascular, neurological, and immunological diseases, little is known about the effect of P. ginseng on autoimmune diseases. Here, we review a few reports about effects of P. ginseng on autoimmune diseases (e.g., multiple sclerosis, Crohn's disease, ulcerative colitis, atopic dermatitis, and rheumatoid arthritis) and suggest the possibility of P. ginseng as a candidate herbal medicine to prevent and treat autoimmune diseases as well as the need to study it.
