In order to confirm the antimutagenicity of ginseng extracts, mutagenicity of ginseng and several medicinal herbs of which extracts were used as drinks, was examined through the method of Ames test. The obtained results were as follows. 1. Strong mutagenicities for Salmonella tyhimurium TA98, TA100, TA1535 were observed in all sample herbs Paenonia aalbiflora, Rehmannia glutinosa, Astragalus membranaceus, Angelica acutiloba, Cnidium officinale, Laurus nobilis and Panax ginseng without S-9 mix metabolic activation. 2. In the case of S-9 mix metabolic activation, even in a low concentraction, the extracts of Angelica autilobu, Cnidium officinale and Paenonla albtilora showed also a high mutagenicities for the strain TA98 and TA1535. 3. Even in high concentration of ginseng extracts, mutagenicity was almost neglectable through the metabolic activation of S-9 mix, compared with other extracts of medicinal herbs.

A statistical analysis of saponin contents in various parts of raw red ginseng was studied. Saponin contents in main lateral and fee roots showed highly significant differences each other. Saponin contents in raw red ginseng had highly negative correlation with the root diameter (r= -0.926**). The estimation of saponin contents at mixing ratios of parts of root appeared to be possible.
Effect of Ethylacetate Fraction and Petroleum Ether Fraction of Ginseng on the Activities of Several Enzymes in Rabbit Liver.
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 15~21
It has been known that ethyl acetate fraction and petroleum ether fraction prepared from ginseng are inhibitory to the L5178Y and sarcoma 180 cell at the concentrations o! 0.Imgfml or 0.2mg/ml. The shiny was carried out to examine effects of the two fractions on the activities of RNA polymerase, succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) present in normal rabbit liver. The ethyl acetate fraction did not show any inhibitory effect on the RNA polymerase and SDH activity at the concentrations of 0.Imgfml and 0.2mglml, but inhibited malate dehydrogenase activity by 12.3% and 15.5%, at the same concentrations, respectively. The fraction also inhibited all the three enzymes at higher concentrations tested, but stimulated the succinate dehydrogenase activity at 0.024mg/ml to increase the enzyme activity by 14.6%. The petroleum ether fraction activated the SDH activity by 12.9% and 20.8%, at the concentration of 0.1mg/ml and 0.2mg/ml respectively. But the fraction did not affect the MDH activity at the same concentration. The fraction, however, inhibited the MDH activity and activated the SDH activity by 13.5% and 18.2%, at the concentration of 0.8mg/ml respectively.
Studies on the Volatile Flavor Components of Fresh Ginseng
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 22~31
Volatile flavor components of fresh ginseng (Panax ginseng C.A. Meyer.) were studied. Steam distillate of fresh ginseng was extracted with ethyl ether and the extract was separated into four fraction: neutral, phenolic, acidic and basis fractions. The ethyl ether concentrates and neutral fraction were analyzed by a combination of SE-54 fused silica capillary gas chromatography and mass spectrometry. Major flavor components of fresh ginseng were predominantly mono(n +2) and sesquiterpenes(n +3) in over two hundred constituents. Of these, 28 were newly identified in volatile flavor components of fresh ginseng by GC-MS.
Study on of Extraction Methods of Saponin in Ginseng Products
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 32~37
In order to shorten the extraction time of saponin in ginseng products, election with Extrelut column and phase-separation methods were compared. The results obtained are as follows. 1. Saponin of ginseng products was extracted completely within 3 hours by election method with Extrelut column, and the rate of removing glucose by the column was increased with increasing glucose content in ginseng products. 2. Stirring method was superior to refluxing method for removing sugars from ginseng products, and removing rate was deceased in the order of lactose, sucrose and glucose. 3. Extraction rate of ginsenoside from ginseng extracts by the elution method was nearly same as that of phase-separation method; however, the former was much higher than the latter in the case of ginseng teas. Therefore, the elution by Extrelut column is to be improper for extraction of saponin in ginseng tea which contains much sugar. It was necessary to remove lipophilic compounds for extraction of saponin from ginseng extracts by elution with Extrelut column.
Influences of Gamma Ray Radiation Doses on Fatty Acid Contents in Ginseng
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 38~44
In order to investigate the influence of gamma-irradiation on fatty acids in ginseng, ginseng were irradiated with various radiation doses(0-50 Mrads). The results are as follows. 1. With increasing dose, standard fatty acids were decreased in the order of linolenic acid, linoleic acid and oleic acid, and their contents in the presence of oxygen were decreased more t than that in the absence of oxygen. 2. Changes of lipid content in white ginseng by gamma irradiation were varied with the samples, but the changes of crude lipid and purified lipid in a sample were showed same fashion. 3. The fatty acid contents in white ginseng were decreased by gamma irradiation in the order of linolenic acid, linoleic acid, oleic acid, stearic acid and palmitic acid.
Characteristics of Flower Organ, Inflorescence and Flowering in Panax ginseng and Panax quinquefolium
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 45~56
This study was carried out to obtain the basic information on the development of flower bud and to clarify the characteristics of flower organ and flowering in Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolium). The formation of flower bud in the dormancy bud of Korean ginseng was initiated about the middle of June and completed late in September. The ovary, style and anther of Panax ginseng, violet-stem and yellow-berry variants, were formed earlier than those of Panax quinquefolium. Panax ginseng, therefore, flowered earlier by one month in comparison with Panax quinquefolium. As for the effect of temperature on the flowering of ginseng, both species, Panax ginseng and Panax quinquefolium, grown at 20
flowered earlier than those at 15
and field conditions, but did not flower at 30
. Seed characters were better in Panax ginseng than in Panax quinquefolium and the amount of seeds showed the highly significant positive correlation coefficient with peduncle length in both Panax ginseng and Panax quinquefolium.
Effect of Seedling Characters on the Growth of Ginseng Plant on Field. .1. Relationship between Seedling Weight and the growth of ginseng plant on field.
Journal of Ginseng Research, volume 8, issue 1, 1984, Pages 57~64
In order to clarify an effect of seedling weight on the growth pattern of ginseng, seedlings ranged from 0.4g plant to 1.8g plant were transplanted, and then the characters of 5- and 6-year-old ginseng were investigated. The characters of root and leaf, such as length and diameter of main root, root weight, leaf area, and leaf dry weight of 5- and 6-year-old ginseng originated from large seedlings were superior as compared with those from small seedlings, and percentage of missing plant was increased with the increase of seedling weight. There were, however, no significant difference in stem length, stem dry weight, number of seeds per plant and number of palmate leaves and leaflets per plant in 5- and 6-year-old ginseng and these characters were not affected by the weight of seedings transplanted. Root field per unit area was higher in seedings of above 0.6g/plant than in small seedlings.

This experiment was carried out to study the effects of light intensity and soil water regimes on the growth of ginseng seedling. The results were as follows: 1. The maximum light intensity and optimum temperature in 1,le photosynthesis of ginseng seedling were 10,000 lux and 23
. Respiration rate was increased at high temperature. 2. Air and soil temperature under the shading were increased as the increase of light intensity but soil water contents were decreased as the increase of light intensity, whereas air and soil temperature were decreased as the increase of precipitation under the shade b5: soil water contents were increased as the increase of precipitation under the shade. 3. The higher the transmittance of the shade, the greater the specific leaf weight (S.L.W.) and stomatal density. In contrast, however, the contents of total chlorophyll, chlorophyll a and b, and stomatal length was decreased. There was no any significant difference light intensity of the a/b ratio of chlorophyll. 4. The highest photosynthesis was occurred in ginseng leaves grown under the shade 5% L.T.R. and net photosynthesis rates increased with increasing soil water contents. 5. Optimum condition for usable seedling yield were 5% L.T.R. and 3.3% precipitation under the shade. Useless seedling increased with increasing precipitation under the shade.
