Preliminary Investigation of Membrane Modifying Effects of Ginseng Components
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 1~9
Prophylactic and curative behaviors of Panax ginseng components (95%, 50% ethanol ext., ginsenoside Re and Ginsana G 115) on the hepatomegaly, lipid peroxidation of the thioacetamide-intoxicated animals in vivo and in vitro were investigated. Ginsenoside Re and Ginsana G 115 significantly decreased in the lipid peroxide formation : the 95% ethanol extract and ginsenoside Re, in the zinc sulfate turbidity test. Besides these investigations, the preventive effect of ginseng components on the degranulation of mast calls in the guinea pig mesentery by compound 48/80 and venom toxin (Agkistrodon piscivourus) was also examined. All ginseng components subjected to this experiment were affected significantly at the different degrees.
Distribution of Saponin in Various Sections of panax ginseng root and Change of Its Contents According to Root Age
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 10~16
This study was carried out to get basic information that can be used in quality control for processing ginseng products and also in separation of pure ginsenosides for experimental purpose. The composition of various parts of 6 year-old ginseng was 4.1% of rhizome (node), 47.7% of main root, 34.1% of lateral root and 14.1% of fine Toot on dried weight basis. The weight ratios of epidermis-cortex and xylem were about 1 : 1 in main root and about 2 : 1 in lateral root. The distribution of total saponin content shows 29.2% in main root, 34.6% in lateral root, 29.1% in fine root and 7% in rhizome, but the order of the content per unit weight was fine root > rhizome > lateral root > main root. Total saponin content according to age of root was increased gradually within 3% for 6 years, as compared with two year old root. In view of the increase of root weight owing to the net amount of saponin in root increased continuously. The increase rates of total saponins per year were 3.1,12.3,19.8,43.8 and 21.1% in 2, 3, 4, 5 and 6 years-old ginseng root, respectively.
Chemical Studies on the Alkaloidal Fraction of Panax ginseng C.A. Meyer (I). TLC Analysis of Various Ginsengs and Identification of an Alkaloid Component
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 17~23
A crude alkaloidal fraction from white ginseng (Panax.gilfsertg C.A. Meyer) showed over thirteen Dragendorff positive spots by TLC using eluent of
/MeOH(10 : 1). TLC pattern of white, red and Sanchii ginseng (P. notoginseng) was mostly not different from each other, but, in American ginseng (P. quinqgtefolium),two spots having Rf 0.71 and 0.68 were not detected. An alkaloid component was isolated from white ginseng and identified as

We studied a assay method on the measurement of superoxide dismutase (SOD Superoxide : superoxide oxidoreductase, EC. 1. 15. 1. 1) activity with photoreduced flavin and nitroblue tetrazolium (NBT) as superoxide (
) source and detector, respectively. The
E (1000 ng SOD
of photoreduced flavin-NBT system was 0.08, whereas that of xanthine-xanthine-cytochrome system used broadly in experiments was 0.014. Therefore, the new method was regarded more simple and utilizable than xanthine-xanthine cytochrome system method. In the present paper, we also carried out to investigate the SOD activity and isozyme pattern for the parpose of study of leaf-burning disease in ginseng (Panax ginseng C.A. Meyer) leaves.
Free Amino Acids of Xylem-Pith in Panax ginseng Root.
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 32~38
Composition of free amino acids (FAA) in the central part (xylem plus piths,of tap root in P. ginseng was investigated in velation to stem status at harvest. The sum of FAA tended to be higher with dead stem than with healthy one but both were not significantly different. The sum of FAA (3.6-4.9% dried weight) was much less than total FAA, suggesting that water soluble nonprotein fraction contained large quantity of ninhydrih positive components except FAA. Pattern of amino acid composition between both stem status was not different. Ten of all 17 amino acids showed increasing tendency with dead stem and two, glutamic acid and cysteine, decreasing. Major FAA were arginine (relative content 58%), glycine (8.2), lysine (5.9), serine (5.7), glutamic acid (4.2) and aspartic acid (3.5). Above facts strongly suggest that the inside white of red ginseng did not closely related with FAA and that early defoliation or stem death did not decrease FAA. The content of arginine was heighest in all cases reported indicating the important role of nitrogen metabolism. Pattern of PAA composition except arginine was not different in present samples but greatly different with other cases reported mainly due to alanine, phenylalanine, glycine and proline.
Effect of Growth Temperature on the Composition of Leaf Lipids in Panax ginseng
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 39~45
Panu ginseng (6 Year old) was grown
night in the light room of phytotron for 84 days. The composition of neutral lipid(NL), glycolipid(GL), phospholipid(PL) and fatty acids were investigated in leaves. The contents of NL and GL were higher in
while PL was lower. Similarity (simple correlation) of lipid composition between
was not significant for PL and GL but significant for NL(p = 0.001), indicating that PL and GL were important factors in the mostability. Similarity of fatty acid composition between growth temperatures was highly significant (p = 0.001) for all three lipids, while similarity between lipids was significant between NL and PL (p=0.01) and NL and GL (p=0.05), but nonsignificant between GL and PL at
. .In NL digalactosyldiacylglycerol (3->
) increased but monogalactosyldiacylglycerol (10%) did not change at
. In PL phosphatidic acid (22 -> 4%) and phosphatidylinositol (18 -> 5%) decreased but phosphatidyl ethanolamine (12->l6%) increased at
. Percent unsaturated acid slightly decreased in NL and PL but greatly increased in GL at
. Percent unsaturated bond slightly decreased in NL but did not change in PL and GL.
Estimation of Yield in Panax ginseng
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 46~55
The regression line was used to predict ginseng root yield from characters of aerial parts, stem diameter, leaf length and width, and degrees of missing plants per unit area. The rates of fitness of predicted yield on practical yield investigated in field were high. Especially, theoretical yield calculated by the size of stem diameter was a good fit. Therefore, a line regression appeared to be a satisfactory fit.
Characteristics of the Growth of Ginseng Tumor Callus
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 56~65
Grown-gall tumor was induced from the infection of Panax ginseng C.A. Meyer by Agrobacterium tumefaciens C58 and the tumor calli were formed on the phytohormone free MS medium. The calli were friable and rough in appearance. Calli obtained from crown gall tumor were similar to and indistinguishable from each other. The tumor callus was quite different from normal callus. Tumor callus grew rapidly, whereas mal callus appeared late. The growth of tumor callus was better in the dark than in the light. In suspension culture, the fresh weight of tumor callus was twice as much in comparison with normal callus.
The Effect of Korean Ginseng on Growth and Harvest of the Rice Plant
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 66~76
When rice seeds were rinsed in If) Korean ginseng tea (KG 722, Korean Ginseng Product Co. Ltd. made) for 28 hours prior to seeding, the early growth was found relatively fast and their resistance against blight and harmful insects was increased. Rice yield showed that control group, rinsing group and spraying group were 514 kg/10a, 562 kg/ 10a and 571 kg/ 10a respectively. However, rinsing and spraying groups were 590 kg/ 10a (leaf spraying) and 605 kg/ 10a (spray immediate after seeding) respectively.
The Effect of Ginseng Saponin Fraction on the Germination and Early Growth of Rice Seed (Oryza sativa L.)
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 77~83
The effects of ginseng saponin on the germination and early growth of rice seeds (Oryza sativa L.) were investigated. The early growth (length) of test rice seeds which were rinsed for 60 hrs in
% saponin solution prior to transplantation to water agar bed was about 20% faster than that of control seeds, It was also found that the amylase activity of the seeds was most active when the seeds were rinsed in 10-4% saponin solution for 48 hrs. In vitro investigation showed that the amylase activities were stimulated about 30% by the treatment of
% saponin solution compared with control group. From the above results, it seems that the ginseng saponin might activate amylase of rice seed during germination, resulting in rapid growth of rice.
Chemical Compositions of Korean Ginseng with Special Reference to the Part of Ginseng Plant
Journal of Ginseng Research, volume 11, issue 1, 1987, Pages 84~89
The contents of some chemical constituents in several parts of Panax ginseng were investigated. Each part of ginseng was extracted with 70% ethanol and then water. The yield of extract was the highest in fine root, and relatively low in roughly dried ginseng and white ginseng, On the other hand, the contents of total sugars in white ginseng and seedling ginseng were high, but low in leaf and peel. The contents of crude protein in roughly dried ginseng and white ginseng were high, but those in leaf, rhizome (nod) and peel were low. The content of crude fat was higher in leaf than in other parts of ginseng plants and that was the lowest in fine root. Among free sugars, the content of fructose was high in leaf and rhizome, but that was the lowest in fine root. In the case of glucose content, leaf contained the highest amount, but fine root did the lowest. Sucrose contents in white, roughly dried and lateral roots were high, whereas that in leaf was low.
