  • This study was carried out to obtain the basic information for the development of new ginseng varieties. The two variants (violet-stem variant and yellow-berry variant) of Korean ginseng (Panax ginseng C.A. Meyer) and American ginseng (Panax quinquefolium L.) of one to four-year were used for this study. All of the characteristics, such as leaf length, leaf width, petiol length, number of leaves per plant, number of leaflets per plants, stem diameter, stem length, number of stems per plant, root length, primary root length, root diameter, root weight were determined and correlations among them were estimated. The results obtained were summarized as follows. 1. Leaf length, petiol length, number of leaves per plant, and number of leaflets per plant of Panax ginseng, violet-stem variant and yellow-berry variant, were larger than those of Panax quinquefolium at all of the plant ages, while leaf width was wider in Panax quinquefolium. 2. The length of stem of Panax quinquefolium was shorter than that of Panax ginseng, and the frequency of multi-stem plants at 4-year-old ginseng was larger in violet-stem variant than in Panax quinquefolium and yellow-berry variant. 3. In the characteristics of ginseng root, the primary root length of Panax ginseng, violet-stem variant and yellow-berry variant, were less than that of Panax quinquefolium, while root weight, root diameter, and umber of secondary root related to yield were larger in Panax ginseng. 4. The root weight per plant related to the yield had positive and highly significant correlations with stem diameter, leaf length, leaf length, leaf width, number of compound leaves and leaflets in Panax ginseng and Panax quinguefolium. 5. The root weight related to the wield of ginseng had been influenced to stem diameter, leaf length, and leaf width directly, and number of compound leaves and leaflets indirectly. 6. The number, total area and activity of stomate per mm2 of Panax quinquefolium were more, larger and stronger than those of Panax ginseng.

  • Background: Both Panax ginseng Meyer and Panax quinquefolius are obligate shade-loving plants whose natural habitats are broadleaved forests of Eastern Asia and North America. Panax species are easily damaged by photoinhibition when they are exposed to high temperatures or insufficient shade. In this study, a cytohistological study of the leaf structures of two of the most well-known Panax species was performed to better understand the physiological processes that limit photosynthesis. Methods: Leaves of ginseng plants grown in soil and hydroponic culture were sectioned for analysis. Leaf structures of both Panax species were observed using a light microscope, scanning electron microscope, and transmission electron microscope. Results: The mesostructure of both P. ginseng and P. quinquefolius frequently had one layer of non-cylindrical palisade cells and three or four layers of spongy parenchymal cells. P. quinquefolius contained a similar number of stomata in the abaxial leaf surface but more tightly appressed enlarged grana stacks than P. ginseng contained. The adaxial surface of the epidermis in P. quinquefolius showed cuticle ridges with a pattern similar to that of P. ginseng. Conclusion: The anatomical leaf structure of both P. ginseng and P. quinquefolius shows that they are typical shade-loving sciophytes. Slight differences in chloroplast structure suggests that the two different species can be authenticated using transmission electron microscopy images, and light-resistant cultivar breeding can be performed via controlling photosynthesis efficiency.

  • The present study was conducted to investigate the ginsenoside profiles of the main root, root hair, and leaf of ginseng in order to demonstrate their possible application in medicine. The total ginsenoside content of the leaf was up to 12 times than that in the main root, and the content of protopanaxadiol groups was higher than that of protopanaxatriol groups in all the samples. The leaf was shown to contain high amounts of ginsenosides Rb3 and Rh1, whereas the main root contained large amounts of ginsenosides Rb1 and Rc. Moreover, Rb2, Rb3, and Rg1 were only detected in the root hair, leaf, and main root, respectively. The ginsenoside Re content of Panax ginseng leaf and root hair was 2.6~4 times higher than that of the main root. Therefore, the results indicate that the ginsenoside content of Panax ginseng is higher in the leaf and root hair, and lower in the main root.

  • This study was conducted to investigate the applicability of the ground parts such as flower (GF), berry (GR), and leaf (GL) from Panax ginseng C. A. Meyer. The ground parts were extracted from hot water (WE) and 60% ethanol (EE). Total polyphenol and flavonoid contents were 15.02-32.74 and 21.60-484.05 mg GAE/g, respectively. Hot water extract of ginseng leaf (GLWE) and 60% ethanol extract of ginseng leaf (GLEE) showed higher total polyphenol and total flavonoid contents than other extracts. Crude saponin contents were found in the range of 15.30-37.27%. Antioxidant activity of these extracts from ginseng was also analyzed by DPPH, ABTS, H2O2 scavenging activity, reducing power, and inhibition effect on lipid peroxidation. We confirmed the results that hot water extract of ginseng leaf (GLWE), 60% ethanol extract of ginseng leaf (GLEE) has high anti-oxidative effects. According to the antioxidant activity results of each extract of ginseng flower, ginseng berry, and ginseng leaf, it is judged that their availability is very high, and if proper processing is performed, it can be used as a functional raw material.

  • Our nation is confronted with the situation that the rice, a principal food, short of some essential amino acids, leads to imbalanced meals insufficient in the nutrient of Protein, to bring many difficulties in the elevation of nutritional state in our nation. While. our country has been produced much amounts of Panax Ginseng roots which has a stimulating effects on the metabolism of protein, lipid and nucleic acids in the body. And the leaf and trunk of Panax Ginseng were also produced a considerable amounts as the by-products. Author believe that these by-products (leaf and trunk) of Panax Ginseng might have some components possessing simillar activity with Panax Ginseng root although the quantity and qualify of the functional components may more or less be different. Therefore, this study was demised to observe the supplemental effect of the Panax Ginseng-by-Products on the dietary protein efficiency and nutritional state of rats. The feeds used for this experiment were rice containing 30% barely, fish four, and the leaf, trunk and small root of the Panax Ginseng, and the contents of the general nutrients including protein, lipid and carbohydrate etc. in each feed were analyzed for the combination of each feed. And, being based on analytical values of Protein in food. fish Pour as Protein source was added were rice containing 30% barely to be include 8.6 to 8.7%, 12%, 15% and 18% of protein. Then 2% of the leaf, trunk or small reef of Panax Ginseng was supplemented into each of above protein diet group, ton 16 kinds of diets were Prepared. The male albino rats from a Pure strain, weighing 70g to 80g. were used for experimental animals. They were maintained with coresponding fist for f and 8 weeks, and the growth rate, consumption of diets and protein, efficiency of feed and Protein in animals were determined. The lipids, proteins and cholesterols in serum and liver were also determined quantitatively after they were sacrificed in coresponding term. The results obtained are summarized as follows: 1. Body weigh of diet group containing 8.6 to 8.7%,12%, and 15% of protein are increased remarkably by supplement of 2% of the leaf or small root of Panax Ginseng in comparison with each of controls. But this tendency could not observed in diet group containing 18eA Proteins. 2. Feed efficiency showed same tendency in comparison with changes of gained body weight. Specially, in each of diets containing 8.7%, 12%, 15% and 18% of Proteins, supplement of the leaf of Panax Ginseng showed the better feed efficiency than supplement of the trunk or small root. 3. In feeding group for 8 weeks, protein efficiency showed worst efficiency in diet containing 18% proteins and showed the best efficiency was the diet group containing 12% Proteins. And the efficiency was improved according to supplement of the leaf of Panax Ginseng. 4. Nitrogen contents in serum and liver did not show large differences each other in all diet groups. But contexts of total cholesterol and 1ipid were decreased markedly in diet groups containing 12%, 15% and 18% of proteins in comparison with diet group containing 8.6% to 8.8% of proteins.

  • Ginseng root has been used as a tonic remedy in Traditional Chinese Medicine for centuries. Modern studies have demonstrated that ginseng root has complex components and multiple pharmacological properties. The effects of ginseng leaf, however, are not well known. Recent studies show that compared to ginseng root, ginseng leaf and stem exhibit a higher content of active compositions such as ginsenosides, polysaccharides, triterpene flavonoids, volatile oil, polyacetylenic alcohols, peptides, amino acids and fatty acids. Ginseng leaf possesses multiple pharmacological effects in the central nervous, cardiovascular, growth and metabolism systems. Additionally, the leaf has anti-fatigue, anti-hyperglycemic, anti-oxidant, and anti-aged effects. In general, ginseng leaf is quite safe, but adverse effects may occur if it is abused or is of poor quality. Thus, attention must be paid to dosages, quality, and standardization of ginseng leaf products.
