  • This work was carried out to establish adventitious root culture system in three Panax species (wild-grown P. ginseng, P. quinquefolium, and P. japonicum) to analyze their ginsenoside productivity. Adventitious roots were induced directly from segments of seedlings after cultured on MS(Murashige andSkoog 1962) solid medium containing 3.0 mg/l IBA. Omission of $NH_4NO_3$ from the medium greatly enhanced both the frequency of adventitious root formation and number of roots per explants in all the three Panax species. However, elongation of post-induced adventitious roots was enhanced on medium with $NH_4NO_3$. Two-step culture protocol: $NH_4NO_3$-free medium for first two weeks of culture, followed by $NH_4NO_3$ containing medium for further 4 weeks, greatly enhanced the fresh weight increase of adventitious roots in all the three ginseng species. The fresh weight of adventitious roots was high in P. quinquefolium and low in P. ginseng, followed by P. japonioum regardless of the composition of medium. Pattern and content of ginsenosides in adventitious roots differed among the three Panax species. Total ginsenoside content of adventitious roots in P. quinquefolium, P. ginseng, and p. japonicum was 8.03, 15.7 and 1.2 mg/g dry weight, respectively. Among the three speices, adventitious roots in P. quinquefolium produced hig-hamount of ginsenosides. The pattern of ginsenoside fractions between P. ginseng and P. quinquefolium was similar but the amount of ginsenoside differed between the two, While, in P japonicum, total ginsenoside content was very low and some ginsenosides such as ginsenoside Rb2 and Rf were not detected. Conclusively, we demonstrate that same culture condition was required for induction and elongation of adventitious roots of three ginseng species but growth of adventitious roots and their ginsenoside production were different among them.

  • Background: Ginseng produced by hydroponics can be cultivated without using agricultural chemicals; thus, it can be used as a raw materials for functional foods, medicines, and cosmetics. This study aimed to determine the optimal harvesting time to obtain the highest levels of ginsenoside and ginseng, as this was not previously unknown. Methods and Results: One-year-old organic ginseng seedlings were transplanted and cultivated using hydroponics for 150 days in a venlo-type greenhouse, using ginseng nursery bed soil and a nutrient solution ($NO_3{^-}-N$; 6.165, P; 3.525, K; 5.625, Ca; 4.365, Mg; 5.085, S; $5.31mEq/{\ell}$). Ginsenoside content and fresh and dry weights were higher at 120 days after transplanting than at 30, 60, 90, and 150 days. Total ginsenoside content was 11.86 times higher in the leaf and stem than in the root at 120 days after transplanting. Ginsenosides F1, F2, F3, and F5 were detected in ginseng leaves and stems. These chemical compounds are known to be effective in altering skin properties, including whitening, anti-inflammation, and anti-aging. Conclusions: Optimal harvesting time for ginseng cultivated using hydroponics was 120 days after transplanting when the biomass and ginsenoside content were highest.

  • Background: Ginseng is a semishade perennial plant cultivated in sloping, sun-shaded areas in Korea. Recently, owing to air-environmental stress and various fungal diseases, greenhouse cultivation has been suggested as an alternative. However, the optimal light transmission rate (LTR) in the greenhouse has not been established. Methods: The effect of LTR on photosynthesis rate, growth, and ginsenoside content of ginseng was examined by growing ginseng at the greenhouse under 6%, 9%, 13%, and 17% of LTR. Results: The light-saturated net photosynthesis rate ($A_{sat}$) and stomatal conductance ($g_{s}$) of ginseng increased until the LTR reached 17% in the early stage of growth, whereas they dropped sharply owing to excessive leaf chlorosis at 17% LTR during the hottest summer period in August. Overall, 6-17% of LTR had no effect on the aerial part of plant length or diameter, whereas 17% and 13% of LRT induced the largest leaf area and the highest root weight, respectively. The total ginsenoside content of the ginseng leaves increased as the LTR increased, and the overall content of protopanaxatriol line ginsenosides was higher than that of protopanaxadiol line ginsenosides. The ginsenoside content of the ginseng roots also increased as the LTR increased, and the total ginsenoside content of ginseng grown at 17% LTR increased by 49.7% and 68.3% more than the ginseng grown at 6% LTR in August and final harvest, respectively. Conclusion: These results indicate that 13-17% of LTR should be recommended for greenhouse cultivation of ginseng.

  • 유기농 인삼 재배는 소비자들의 안정적인 농산물의 요구에 따라 급증한다. 반면에 유기농과 관행 인삼재배의 토양 무기성분 및 인삼의 진세노사이드함량 차이에 관한 연구는 아직 까지 미흡한 실정이다. 따라서 본 연구는 토양화학성 및 진세노사이드 함량을 비교해 관행인삼과 유기농인삼의 차이를 구명하는데 목적을 두고 있다. 질산태 질소, 가용성인산, 치환성 칼륨함량은 유기농재배와 관행재배 간에 유의성 있는 차이를 보였다. 비록 유의성 있게 차이는 없었지만 총 진세노사이드함량 뿐만 아니라 대부분 개별 진세노사이드는 관행재배 인삼보다 유기농재배 인삼에서 더 높은 함량을 보였다. 특히 유기농 인삼은 관행인삼에 비해 PT계열의 사포닌 보다 PD계열의 사포닌 함량이 더 높았다. 질산태 질소는 Ginsenoside $Rb_2$, Rd와 부의 상관관계를 보였다. 반면에 유효인산함량은 $Rb_1$, Rc, PD/PT비율과 부의 상관관계를 보였다. 인삼의 Ginsenosdie 성분들을 증가시키려면 질산태 질소과 인삼함량을 줄이고 유기물함량을 높여야 한다.

  • Panax ginseng is one of the most important medicinal plants in Asia. Triterpene saponins, known as ginsenosides, are the major pharmacological compounds in P. ginseng. The present study was conducted to evaluate the changes in ginsenoside composition according to the foliation stage of P. ginseng cultured in a hydroponic system. Among the three tested growth stages (closed, intermediate, and opened), the highest amount of total ginsenoside in the main and fine roots was in the intermediate stage. In the leaves, the highest amount of total ginsenoside was in the opened stage. The total ginsenoside content of the ginseng leaf was markedly increased in the transition from the closed to intermediate stage, and increased more slowly from the intermediate to opened leaf stage, suggesting active biosynthesis of ginsenosides in the leaf. Conversely, the total ginsenoside content of the main and fine roots decreased from the intermediate to opened leaf stage. This suggests movement of ginsenosides during foliation from the root to the leaf, or vice versa. The difference in the composition of ginsenosides between the leaf and root in each stage of foliation suggests that the ginsenoside profile is affected by foliation stage, and this profile differs in each organ of the plant. These results suggest that protopanaxadiol- and protopanaxatriol(PPT)-type ginsenosides are produced according to growth stage to meet different needs in the growth and defense of ginseng. The higher content of PPT-type ginsenosides in leaves could be related to the positive correlation between light and PPT-type ginsenosides.

  • For the elucidation of significance of saponin as quality criterion of ginseng ginsenoside content(GC) and ginsenoside pattern similarity(GPS) by simple correlation were investigated in relation to red ginseng quality factors, age, plant part, harvest season, mineral nutrition, soil physical characteristics, growth light and temperature, shading material, growth location, physiological disease and crop stand through survey of ginseng plantstions, field experiments, water culture and phytotron experiments. Effect of tissue culture was also reviewed. GC was negatively correlated with good quality of red ·ginseng and positively with bad quality. Age did not show any consistency with GC but GPS was less with the increase of age difference. GPS was less or not significant between taproot that is lowest in GC and epidermis highest, and significant between leaf and taproot. Harvest season marked with the lowest GC and Pattern was also different. Nutrient imbalance, the increase of hazardous soil nutrient and physical condition to growth increased GC, but GPS was little different. The higher the growth lights intensity and temperature the higher the GC but GPS was little changed. Root rust increased GC, but root scab decreased it. Sponge-like and inside cavity phenomena increased GC. Ginsenoside pattern of cultured tissues and rootlet showed great variation. These results strongly indicate that there are optimum saponin content and ginsenoside pattern and that these are accomplished under the optimum growth condition.

  • This study was conducted to investigate the difference of general feature and ginsenoside content of 6 years old ginseng root among different grade of roots. Total weight of a 1st grade-6 years old ginseng root was 115.1g and weight, length, diameter and specific gravity of main root were 64.68g, 8.39cm, 3.31cm and 0.96, respectively. Main root of 1st grade ginseng root was larger in size and specific gravity and more heavy than that of End or 3rd grade of the roots. Though crude saponin contents were not so different among the different grade of roots, but ginsenoside Rb1, Rg1 and Re content were higher in 1st grade of root than that of 2nd or 3rd grade of root. Those ginsenosides were located mainly in periderm and cortex.

  • The roots of Korean ginseng (Panax ginseng) have a long history of usage as a medicinal drug. Ginsenosides, a group of triterpenioid saponins in ginseng, have been reported to show important pharmacological effects. Many studies have attempted to identify the ginsenoside synthesis pathways of P. ginseng and to increase crop productivity. Recent studies have shown that exogenous gibberellin (GA) treatments promote storage root secondary growth by integration of the modulating cambium stem cell homeostasis with a secondary cell wall-related gene network. However, the dynamic regulation of ginsenoside synthesis-related genes and their contents by external signaling cues has been rarely evaluated. In this study, we confirmed that GA treatment not only enhanced the secondary growth of P. ginseng storage roots, but also significantly enriched the terpenoid biosynthesis process in RNA-seq analysis. Consistently, we also found that the expression of most genes involved in the ginsenoside synthesis pathways, including those encoding methylerythritol-4-phosphate (MEP) and mevalonate (MVA), and the saponin content in both leaves and roots was increased by exogenous GA application. These results can be used in future development of biotechnology for ginseng breeding and enhancement of saponin content.

  • Ginseng products available in different forms and preparations are reported to have varied bioactivities and chemical compositions. In our previous study, four new dammarane-type ginsenosides were isolated from Panax ginseng, which are ginsenoside Rg18 (1), 6-acetyl ginsenoside Rg3 (2), ginsenoside Rs11 (3), and ginsenoside Re7 (4). Accordingly, the goal of this study was to determine the distribution and content of these newly characterized ginsenosides in different ginseng products. The content of compounds 1 - 4 in different ginseng products was determined via HPLC-UV. The samples included ginseng roots from different ginseng species, roots harvested from different localities in Korea, and samples harvested at different cultivation ages and processed under different manufacturing methods. The four ginsenosides were present at varying concentrations in the different ginseng samples examined. The variations in their content could be attributed to species variation, and differences in cultivation conditions and manufacturing methods. The total concentration of compounds 1 - 4 were highest in ginseng obtained from Geumsan ($185{\mu}g/g$), white-6 yr ginseng ($150{\mu}g/g$), and P. quinquefolius ($186{\mu}g/g$). The results of this study provide a basis for the optimization of cultivation conditions and manufacturing methods to maximize the yield of the four new ginsenosides in ginseng.
