The effects of water extracts and powder of Korean ginseng on the division of Saccharomyces cerevisiae were studied. 1. The addition of several doses of water extracts and powder of ginseng to the yeast medium of Moyer and Coghill showed various promoted division of Saccharomyces. 2. The optimal dose of ginseng on tile division of Saccharomyces (0.08% dry ginseng medium solution per $10\;cells/mm^3$) could be recognized. 3. On the culture for 24 hours at $18^{\circ}C$, the cell number of control group was $13.25{\times}10^3\;cells/mm^3$ and that of the optimal dose group of water extracts of ginseng was $23.20{\times}10^3\;cells/mm^3$. On the culture, for 24 hours at $25^{\circ}C$, the cell number of control group was $16.85{\times}10^3\;cells/mm^3$ and that of the optimal dose group was $30.20{\times}10^3\;cells/mm^3$. The increasing rate of cell divison by the ginseng was about twice than that of control group. The optimal dose treatment of ginseng at $18^{\circ}C$ was more effective than control group at $25^{\circ}C$. 4. On the culture for 24 hours at $18^{\circ}C$, the increasing rate of water extracts of ginseng was 75.1%, and the rate of ginseng powder was 7.6%. On the culture for 24 hours at $25^{\circ}C$, the rate of water extracts of ginseng was 79.8%, and the rate of ginseng powder was 57.2%. Therefore water extracts of ginseng was more effective than ginseng powder of same dry weight, and the promoted effect of ginseng powder at $25^{\circ}C$ was more effective than at $18^{\circ}C$.

The effects of ginseng on the penetration of glucose into Saccharomyces cerevisiae were studied by determining the amount of glucose in the supernatant of the glucose broth medium in which some dose of water extracts of ginseng or saponin were added and the yeast was cultured for 1 hour. 1. In the 1 hour culture with 0.04%, 0.08%, 0.16%, 0.32% and 0.64% dry ginseng glucose broth medium, the penetration rate of glucose into yeast was increased 4.76%, 7.96%, 10.09%, 9.08% and 7.48% respectively. 2. In the 1 hour culture with $10^{-6}%,\;10^{-5}%,\;10^{-4}%,\;10^{-3}%,\;and\; 10^{-2}%$ of saponin glucose broth medium, the penetration rate of glucose into yeast was increased 3.05%, 6.57%, 5.595, 4.44%. and 2.87% respectively. 3. Since the highest increasing percentage of penetration of ginseng and saponin were 10.19% and 5.89% respectively, the increasing rate of the ginseng was about twice that of the saponin. Therefore it could be concluded that the saponin contained in ginseng and other unkown components of ginseng affect the cell permeability.

1. To know the site of saponin synthesis in this plant, 4-years old Panax ginseng C.A. Meyer was administered with 1, 2-l4C-acetate (Na salt, 10 ucilplant) by stem injection and was continued to grow for 3 weeks and the distribution of the radioactivity in leaf, stem and root part was identified. The percentage of radioactivity recovered was about 3.99%. 2. The sliced roots or leaf discs (2g) were bathed in the reaction mixture containing sugar, ATP, NADPH, and the distribution of the radioactivity of the fractions (sugar, saponin, sapogenin) was identified. 3. It seemed that major synthesized saponins in roots and leaves are dial and triol-type, respectively. Although both types of saponins are synthesized in roots, the main saponins seemed to be dial saponins and a significant portion of triol saponins are supplied from leaves through stem.

The effects of saponin and histamine solution on the division of Saccharomyces cerevisiae were compared with the effects of ginseng on the division. 1. $10^{-2},\;10^{-3}%$ saponines were inhibitory on the division but $10^{-5}%$ saponin increased slightly the division, however its increasing rate was much less than that of ginseng. 2. 0.5% histamine was inhibitory on the division but $10^{-2}%$ histamine increased the division, however its increasing rate was higher than that of saponin and lower than that of ginseng. 3. Although some doses of saponin and histamine were inhibitory on the division, the increasing dose of saponin or histamine on the division could be recognized as shown in the case of the optimal dose of ginseng.

In the screening of those components with comparatively strong xanthine oxidase inhibition activities from Panax ginseng folium. trifolin. panasenoside. kaempferol and so far unconfirmed phenol whose chemical structure still without elucidation have been discovered as such components. Specific inhibitors of xanthine oxidase are thought to be therapeutically useful for the treatment of gout. Such opinion is considered to be useful to support the thought that ginseng folium is effective for the adjustment of gout. Although trifolin. panasenoside. and kaempferol are well known flavonoids. further studies on unidentified new phenols should be continued.

Crude ginseng saponin fraction reduced the production of thromboxane $A_2$in the lipopolysaccharide-stimulated macrophages. Several kinds of crude saponins showed variant potency that might be caused by the compositional difference of ginseng saponins. From the metabolic labeling experimental data, this reduction of thromboxane $A_2$formation, at least in part, resulted from the reduction of protein synthesis of inducible isozyme of cyclooxygenase(COX-2). This activity may be resulted from the fact that ginseng saponins have steroidal moiety in their structures.

Panax ginseng C.A. Meyer(Araliaceae) has been traditionally used as an expensive and precious medicine in oriental countries for more than 5, 000 years. Ginseng saponin isolated from the root of Panax ginseng have been regarded as the main effective components responsible for the pharmacological and biological activities. Such as antiaging effects. antidiabetic effects anticancer effects. Protection against physical and chemical stress. Analgesic and antipyretic effects. Effects on the central nervous system, tranquilizing action and others. Thirty kinds of ginsenosides have been so far isolated from ginseng saponin and their chemical structures have been elucidated since 1960's. Among which protopanaxadiol type is 19 kinds. protopanaxatriol type. 10 kinds and oleanane type, one. Since ginsenosides are generally labile under acidic conditions ordinary acid hydrolysis is always accompanied by many side reactions, such as epimerization. hydroxylation and cyclization of side chain of the sapogenins Especially. it is well known that C-20 glycosyl linkage of ginsenoside was hydrolysed on heating with acetic acid to give an equilibrated mixture of 20(S) and 20(R) epimers. And also, the chemical transformations of the secondary metabolites have appeared during the steaming process to prepare red ginseng. Indicating demalonylation of malonyl ginsenosides, elimination of glycosyl residue at C-20 and isomerization of hydroxyl configuration at C-20. But these studies have not provided a comprehensive picture in explaning how these ginsenosides showed val'iotas pharmacological activities of ginseng. Though some of them have been involved in the mechanism of pharmacological actions. Recently, non-saponin components have received a great deal of attention for their antioxidant, anticancer antidiabetic, immunomodulating. anticomplementary activities and so on. To meet the demand for such wide applications, studies on the non-saponin components play an important role in providing a good evidence of pharmacological and biol ogical activities. Among the non-saponin constituents of Korean ginseng, polyacetylenes, phenols. Sesquiterpenes, alkaloids. polysaccharides oligosaccharides, oligopeptides and aminoglycosides together with ginsenosides of terrestrial part are mainly described.

This study was carried to investigate the effect of illite addition on the growth, bioactive components and volatile compounds of leaf on Saururus chinensis Baill cultivation in greenhouse. Illite addition on Saururus chinensis Baill cultivation resulted no significant effects on the aerial part. However, the root part was highest in 5% illite addition group. Crude oil and ash amount increased as illite additives was increased. Ca of inorganics and free sugars contents were highest in 5% and 20% illite addition, respectively. Hyperoside and isoquercetin of available component on leaf were highest in 5% illite addition group, 4.02mg/g and 4.31mg/g, respectively. The volatile compounds in Saururus chinensis Baill leaf cultured with illite addition amounts were isolated by solid-phase microextraction fiber (polydimethysiloxane $65{\mu}m$) and identifed by gas chromatogtaphy mass spectrometry. As the results, the 22 volatile compounds were identified from in Saururus chinensis Baill leaf and major volatile compounds were the ${\alpha}$-cadinol (18.50%), myristicin (16.46%), methyl-9-methyl-tetradecanoate (10.22%), and ${\gamma}$-muurolene (9.75%). Especially, the content of ${\alpha}$-cadinol was highest in 5% illite addition group and ${\gamma}$-muurolene on overall illite addition group was lower than no addition group.

This experiment was carried out to select suitable organic matter in To-jik nursery (self soil nursery) for complement To-jik nursery's defects that are deterioration of raw material by poor quality of seed ginseng and reduction of the quantity in seed ginseng production. Organic matter used were Yacto, rice bean, defatted rice bran, soybean cake and their mixture. As follows, bulk density in soil physical property by treating organic composts was the greatest in soybean cake and the next was followed by mix, Yacto, defatted rice bran, and rice bran treatment in order. Soil pore space ratio was totally the opposite; that was rice bran the first and followed by defatted rice bran, Yacto, mix and soybean cake treatment. The incidence rate of damping off by treating organic composts was 1.5% in both soybean cake and mix while the others was 1.0%. Emergence time was the same among treatment on April 16 and Emergence rate was the highest at 73% in Yacto. There was no significant differences among treatment in the growth of aboveground part but it was a little better in defatted rice bran treatment. In Yacto treatment, the growth of underground part, total root number per kan, rate of first grade ginseng seedling, and rate of usable ginseng seedling etc. were entirely higher but there was little differences. Using defatted rice bran was slightly lower in productivity compared to Yacto, but the possibility was high as a alternative for Yacto in a view of managing cost down.

This study was carried out to determine changes in general chemical composition, free sugars, physicochemical properties of extract, and ginsenoside contents depending upon processing methods. Ginseng roots harvested from the same field were employed for the processing into white ginseng (WG), taegeuk ginseng (TG), red ginseng A (RGA, steamed one time), and red ginseng B (RGB, steamed three times). The fat content decreased by increasing duration of treatment and number of steaming treatment. On the other hand, there was no significant variation in contents of ash and carbohydrate depending on processing methods. Contents of sucrose and maltose was higher in Taegeuk and red ginseng than those of white ginseng. Steamed ginseng root (taegeuk and red ginseng root) showed higher amount of water extractable solid than the unsteamed white ginseng, but the variation of crude saponin content was not distinctive depending on processing methods. The contents of total ginsenosides increased by the order of white, taegeuk, red A, and red B root. In summary, chemical composition and total ginsenoside content were different according to part of root and processing methods, thus implies the importance of quality control as well as pharmacological activity of ginseng root.
