Effect of Extraction and Evaporating Conditions on the Free SuEar in Contents Ginseng Extract
Journal of Ginseng Research, volume 6, issue 2, 1982, Pages 115~122
This studies were conducted to investigate the effect of extraction and evaporating conditions on the free sugar in ginseng extracts. Raw ginseng roots were extracted with water or various concentration of water-ethanol solutions. Then the extracts were evaporated by boiling or vacuum evaporated at 50
. The results are as follows Sucrose and maltose contents were 7.95% and 12.8% in water extracts and 19.96%, 0.34-0.93% in 90% ethanol extracts, respectively. On the otherhand, glucose and fructose contents were not affected by the solvents. Evaporating conditions, such as temperature, were rarely effected to the sugar contents.

Journal of Ginseng Research, volume 6, issue 2, 1982, Pages 123~130
Studies were carried out to clarify the effect of ginsenoside-Rbl -Rbr and acid hydrolyzatps of ginsenoside-Rbl, -Rb2 (HRbl, HRbf) on lipolysis and lipogenesis induced by epinephrine, glucagon, ACTH (adrenocorticotrophic hormone), TSH (thyroid-stimulating hormone) and insulin in rat adipose tissilr. HRbl , HRb2 slightly inhibited lipolysis induced by epinephine. glucagon and TSH. ACTH-induced lipolysis in fat tissue slices was significantly inhibited by ginsenoside -Rbl, -Rb2, HRbl and HRb2, particulary HRb2. None of ginsenoside-Rbl, -Rb2, HRbl and HRb2 accelerated insulin-stimulated lipogenesis in fat calls. Among ginseng products, extract powder (freeze dried), extract powder (spray dried), red ginseng powder inhibited ACTH-induced lipolysis in adipose tissue slices, but red ginseng extract not affect them

Journal of Ginseng Research, volume 6, issue 2, 1982, Pages 131~137
The effect of red ginseng residue on the several enzyme activities of the koji and alcohol fermentation were investigated. The koji showed maximum values of amylase and cellulase activity when it was prepared by 30% red ginseng residue and 70% wheat bran, and of protease activity when it was prepared by 40% red ginseng residue and 60% wheat bran-
amylase activity of the koji during its fermentation was increased rapidly until 4 days and there after it was increased slowly, but
-amylase was rapidly increased after 3 days fermentation. During the preparation of the koji, the acidic, neutral protease and cellulase activities showed the maximum value after 3 days fermentation and the alkaline protease showed the maximum value within 4-6 days fermentation. On the otherhand, fermented broth, containing 6%(v/v) alcohol, could be obtained when the substrate was saccharified by the koji, based on 25% red ginseng residue and 75% wheat bran, prior to alcohol fermentation.

The composition and concentration of ginsenosides and the free sugars in panax ginseng(Korea ginseng), panax quinquefolium (American ginseng) and panax pseudoginseng var. notoginseng (Sanchi ginseng), were investigated. The major ginsenosides and the order of their amount in panax ginseng are Rbl, Rc Rgl, Re, Rb2 Rd and these are about 90% of total ginsenosides, but major ginsenosides of American and Snachi ginseng art Rbl, Re, Rg1 (about 91% of total) ansi Rgl, Rbl, Re (about 93% of total) respectively. Sanchi ginseng was observed in higher concentration of panaxatriol than panaxadiol unlike panax and American ginseng. Free sugars in white ginseng are fructose, glucose, maltose and sucrose. Whereas, in red ginseng rhamnose and xylose were also detected as free sugar.

This study was conducted to investigate to select the optimum condition for the sterilization of white ginseng powder. The powder heated at 100-121
for 1-30 minutes in a autoclave and irradiated at 2450 MHz microwave for 0.5-3.0 minutes was significantly changed in it's color density and become coagulated state, but their sterilizing effect on a general bacteria and 5. coli group were negligible. Meanwhile W- irradiation to the powder with thickness 1.5-10.5mm for 120 minutes was no changes in it's color. coagulated state and sterilizing effect, but 60Co-
ray irradiation at various dose with 0.1-2.0 Mrad was significant effect for sterilization and stability of the powder during the storage for 4 months at 25
. The optimum dose of 60Co-
ray irradiation was 0.5-0.7 Mrad.
Studies on the Optimum Light Intensity for Growth of Panu ginseng (II) Study on the difference of the optimum light intensity for the growth of ginseng Plant accordingto the root age
Journal of Ginseng Research, volume 6, issue 2, 1982, Pages 149~153
To investigate the effect of light intensity on the growth of shoots and roots, water and chlorophyll contents in the ginseng leaf were determined at 5%, l0%, 20%, 30% light transmittance rate (LTR) with 1,2 and 4 year-old ginseng plants in the field. Stem length, size of the leaf, water and chlorophyll contents were decreased as the increase of the light intensity in all ages of ginseng plants. The degree of decrease was severe in the one year-old ginseng compared to that of 2, or 4 year-old ginseng, while there was no difference between the 2 and 4 year-old plants. Root weight per plant was highest at 5% LTR in the one year-old plants, while it was at 20% LTR in the 2 and 4 year-old plants. Generally, demand of light for the growth of one year-old ginseng was lower than those of 2 or 4 year-old plants there was no difference of it among the ginseng plants older than 2 years.

To determine the effects of mulching with the hulls of rice on the growth of the ginseng plant and changes of its growing environment-soil moisture content. subterranccan temperature and soil hardness- were investigated under different light intensity such as 5%, 10%, 20%, and 30% light transmittance rate(LTR). The results obtained were as follows; 1. Soil moisture content under the shading was decreased as the increase of light intensity, whereas it was increased about 1.5% in each plot of LTR by the mulching. 2. Suberranccan temperature under the shading was increased as the increase of light intensity. It was decreased on a hot day by the mulching but increased on a cold day. 3. Soil hardness was decreased by the mulching. 4. Sprouting date of the ginseng plants was acclerated for 7 days and sprout periods were shortened for f days by mulching compared to the non-mulching treatment. 5. Missing plant rate was increased severely as the increase of light intensity more Than 20% LTR In the non-mulching plots but did not severe in the mulching plots. Missing plant rate was decreased remarkably by the mulching. The degree of decrease was larger as the increase 6f light intensity. 6. Root yield was increased in the mulching plots compared to the non
mulching plots. The degree of increase was larger as the increase of light intensity. The highest yield was obtained at 20% LTR with mulching.

Calli and leaflets of ginseng (Panax ginseng C.A. Meyer) were cultured on 1/2MS media supplement. with kinetin, 2 iP, NAA, 2,4-D and IBA to assess their capacity to regenerate embryoids and organs. Root calli produced numerous embryoids and shoots in 1/2MS medium supplemented with 2 mg/l NAA and 2mg/s 2iP, and the combination of 2 iP and NAA was more effective than the combination of kinetin and NAA in induction of embryoid and shoot from root calli. Culture of leaflet in the medium supplemented with IBA resulted in profuse root regeneration.
Water Physiology of Panax ginseng III. Soil moisture, physiological disorder, diseases, insects and quality
Journal of Ginseng Research, volume 6, issue 2, 1982, Pages 168~203
Effects of soil moisture on growth of Panax ginseng, of various factors on soil moisture, and of moisture on nutrition, quality, physiological disorder, diseases and insect damage were reviewed. Optimum soil moisture was 32% of field capacity with sand during seed dehiscence, and 55-65% for plant growth in the fields. Optimum soil moisture content for growth was higher for aerial part than for root and higher for width than for length. Soil factors for high yield in ginseng fields appeared to be organic matter, silt, clay, agreggation, and porosity that contributed more to water holding capacity than rain fall did, and to drainage. Most practices for field preparation aimed to control soil moisture rather than nutrients and pathogens. Light intensity was a primary factor affecting soil moisture content through evaporation. Straw mulching was best for the increase of soil moisture especially in rear side of bed. Translocation to aerial part was inhibited by water stress in order of Mg, p, Ca, N an Mn while accelerated in order of Fe, Zn and K. Most physiological disorders(leaf yellowing, early leaf fall, papery leaf spot, root reddening, root scab, root cracking, root dormancy) and quality factors were mainly related to water stress. Most critical diseases were due to stress, excess and variation of soil water, and heavy rain fall. The role of water should be studied in multidiciplinary, especially in physiology and pathology.
