This study compared the contents of ginsenosides depending on steaming conditions of red ginsengs to provide basic information for developing functional foods using red ginsengs. The red ginseng steamed eight times at $98^{\circ}C$ ranked atop the amounts of prosapogenins ever detected in red ginsengs (ginsenoside $Rg_2$, $Rg_3$, $Rg_5$, $Rg_6$, $Rh_1$, $Rh_4$, $Rk_1$, $Rk_3$, $F_1$, $F_4$, 1.15%) among red ginsengs steamed more than twice. When steamed eight times at $98^{\circ}C$, 2.7 times as much prosapogenins such as ginsenosides $Rg_2$, $Rg_3$, $Rg_5$, $Rg_6$, $Rh_1$, $Rh_4$, $Rk_1$, $Rk_3$, $F_1$, and $F_4$ as those steamed just once at $98^{\circ}C$ was collected. In addition, the red ginsengs steamed eight times at $98^{\circ}C$ contained more amounting ginsenoside $Rg_3$ (0.28%) than that in the red ginseng steamed several times at random. Accordingly, it is recommendable that red ginsengs steamed 8 times, which proved to be the optimal steaming condition, be used rather than those steamed 9 times (black ginsengs), in order to develop red ginseng products of high prosapogenin concentration and high functions.

Geochemical relationships between ginsengs and soils from three representative soil types, shale, phyllite and granite regions, from Keumsan were examined. High elements ere shown at the granite and shale areas of the weathered soils, the phyllite areas of he cultivated soils and the shale areas of the host rocks. T1 was enriched in ginsengs grown in the shale areas, Cs and B in the phyllite areas, and Be and Cd in the granite areas. Positive correlations were dominated by the shale areas. These relationships can be explained for mineral characteristics within the soils, and their behaviors related to the physio-chemical conditions. High elements were shown in the 2 year ginsengs of the hale areas, and 4 year ginsengs of the phyllite and granite areas in comparisons with ginsengs of the different ages from the same areas. These differences can be explained with ages of the ginsengs, solubilities of the minerals and physio-chemical differences within soils. The content differences of high elements such as Cs, T1 and Be were found between soils and ginsengs. Overall, these results suggest that components of ginsengs grown in the granite areas are chemically similar to the soils.

This study is for geochemical relationships between ginsengs and soils from three representative soil types from Keumsan, shale, phyllite and granite areas. For this study, ginsengs (2, 3 and 4 years), with the soils and their host rock, are collected and are analysed for the transitional elements. In the weathered soils, the shale area is high in the most of elements, but low in the granite area. High correlation relationships are shown in the shale area. In the field soils, the shale area is mainly high, but low in the granite area. Comparing with ages, most of elements are high in the 2 year soils, but low in the 4 year soils. Regardless of the localities, positive and negative correlations are dominant in the shale area. In the host rocks, high element contents are shown in the phyllite and shale areas. Positive and negative correlations are found in the shale and phyllite areas for large numbers of the element pairs. In the ginsengs, differences of the element contents with ages are not clear, but show high element contents in the 2 year ginsengs of the shale and phyllite areas, and low contents in the 4 year ginsengs of the granite area. Positive correlations are shown in the Cu-Zn pair in the shale and phyllite areas, and Co-Cu pair in the granite area. In the relative ratios(weathered soil/field soil), most of elements from the shale area are high, above I, suggesting high element contents in the weathered soils of the shale area relative to the granite and phyllite areas. In the relative ratios(weathered soil/host rock), most of elements are above 1, suggesting the high element contents in the weathered soils relative to the host rocks. Relative ratios (soil/ginseng) of the element contents are several to ten times. Regardless of the areas, big differences of the relative ratios are found in the Co and small differences are in the Cu and Zn, which suggest that differences between soils and ginsengs are big in the Co contents and small in the Cu and Zn contents. Regardless of the ages, differences among relative ratios are small in granite area relative to the shale area, which suggest more similar contents between ginsengs and soils in the granite areas.

Lipid and fatty acid compositions of the free lipids in Panax ginseng (Korea, Japan and China), Panax quinquefolium (America, Canada) and Panax notoginseng (China) were studied by means of silicic acid column chromatography, thin-layer chromatography and gas-liquid chromatography. Free lipid contents were 1.13 to 1.24% in panax ginseng and 0.87 to 1.18% in Panax quinquefolium and 0.39% in panax notoginseng. Neutral lipid fractions were 81.2 to 84.4%, while glycolipid fractions 8.01% to 14.47% and phospholipid fractions 3.49 to 5.74% in free lipid contents. The major components were triglycerides, free sterols, diglyceride, free fatty acids and sterol esters in neutral lipid fractions, sterol glucoside, monogalactosyl diglyceride, digalactosyl diglyceride, esterified steryl glucoside in glycolipid fractions and phosphatidyl glycerol, phosphatide, ethanolamine, phosphatidyl choline in phospholipid fractions. The contents and compositions of neutral lipids and glyclipids were some different among various ginsengs, whereas phospholipids showed relatively similar compositions in the contents. Seventeen fatty acids were analyzed in the four free lipid fractions from the various ginsengs and the main fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid. It was found that the amounts of some fatty acids were different among the various ginsengs, but the fatty acid patterns of these ginsengs were on the whole similar.

Comparative cytotoxic activities of petroleum ether soluble fraction from various ginsengs of Panax species were evaluated using A549 (human lung adenocarcinoma) and SK-OV-3(human ovary carcinoma) cancer cell lines. Korean red ginseng, Korean white ginseng, American ginseng and Canadian ginseng were found to show more potent cytotoxicitles on A549 and SK-OV-3 cell lines than Chinese red ginseng, Japanese red ginseng and Sanchi ginseng. It is noteworthy that especially, red ginseng prepared from the root of Panax ginseng cultivated in Korea shows relatively stronger cytotoxic activities than those cultivated in China and Japan.

We have compared the panaxadiol and panaxatriol contents of white ginsengs from different countries and red ginseng, by using gas and high-pressure liquid chromatographies. Oleanolic acid contents in various ginseng species were compared by gas liquid chromatography and densitometry. Korean ginseng was found to contain greater amount of panaxadiol and panaxatriol than those of any other countries. The ginsengs from other countries, especially Chikusetzu ginseng, were found to contain far greater amount of oleanolic acid than Korean ginseng.

This study is for geochemical relationships between ginsengs and soils from three representative soil types from Keumsan, shale, phyllite and granite. For these study, ginsengs, with the field and weathered soils were collected from the three regions, and are analysed for the major and trace elements. In the weathered soils(avg.), the granite and phyllite areas are high in the most of elements while the shale area is low. In the correlation coefficients, negative correlations are shown in the $Al_2O_3$-MgO pair while positive correlations, are shown in the Ba-Sr, Zr, Sr-Zr and Cs-Ge pairs. In the field soils(avg.), the granite and phyllite areas are, generally, high in the most of elements while the shale area is low. In the shale area, the major elements are high in the 4 year soils, but low in the 2 year soils. The LFS(Ba, Sr, Cs) and transitional elements are high in the 2 year soils, but low in the 4 year soils. The HFS(Y, Zr) is high in the 4 year soils. In the correlation coefficients, most of the elements from the 4 year show positive relationships. Positive correlations are shown in the $Al_2O_3$-CaO, MnO-MgO, V-Tl, and Ba-Sr pairs in all localities. In the ginseng contents, clear chemical differences with the ages are shown in the shale and granite ares, but not clear in the phyllite area. In the shale area Mn, Mg, Ba, Sr, and Y contents, increase with ages but decrease in Al, Cs, Be and Cd. In the correlation coefficients, degrees of the correlations for the major elements become low with the ages. Positive correlations are shown in the Al-Mn, Ti, Mn-Ti, Mg-Ca, Ca-K, Ba-Cs, Y and Cs-Y pairs. Comparisons with ginsengs of the same ages from the different areas suggest that generally, the 2 years in the shale and 3 and 4 years in the granite area are distinctive. Relative ratios(granite/ shale area) of the ginsengs are below 1 in the major elements except Mn in the 2 year ginsengs and above 1 in the other elements except Mg and Na in the 4 year. Relative ratios(granite/ phyllite area) of the ginsengs are high in the 3 year from the phyllite area. In the relative ratios(weathered/field soils) of the soils, numbers of the elements showing the ratios of above 1 increase from the shale, to phyllite and granite in the case of the major elements, but decrease in the case of the trace elements. These results suggest that major elements are high in the granite while trace elements are high in the shale area. In the relative ratios between field soils and ginsengs(field soils/ginseng), the shale area, regardless of the ages, show differences of several hundred times in the $Al_2O_3$, $TiO_2$, Y and Tl, of several ten times in the MnO, MgO and Ba and of several times in the CaO contents. These results suggest that ginseng contents are significantly different from the field soils in the $Al_2O_3$, $TiO_2$, Y and Tl, but similar in the CaO contents. The phyllite area, regardless of the ages, show differences of several hundred times in the $Al_2O_3$, $TiO_2$, Y, Tl and Be, of several ten times in the MnO, MgO, $Na_2O$ and Ba, and of several times to ten times in the CaO, $K_2O$ and Sr contents. These results suggest that ginseng contents are significantly different from those of the field soils in the $Al_2O_3$, $TiO_2$, Y, Tl and Be, but similar in the CaO, $K_2O$ and Sr contents. The granite area, regardless of the ages, show differences of several hundred times in the $Al_2O_3$, $TiO_2$, Tl and Be, of several ten times in the Ba, and of several times to ten times in the MgO and CaO contents. Of the other elements, differences of several times to ten times are shown in the MnO, $K_2O$ and Sr contents. These results suggest that ginseng contents are significantly different from those of the field soils in the $Al_2O_3$, $TiO_2$, Tl and Be, but similar in the $K_2O$ and Sr contents. Comparisons among the different ages from the same area suggest that, in the case of shale area, differences of several hundred times in the $Al_2O_3$ and $TiO_2$, of the several ten times in the MnO, MgO and Ba and several times in the CaO and $K_2O$ are shown in the 2 year ginsengs. Differences of several hundred times in the $Al_2O_3$, $TiO_2$, Cs, Y, Tl and Be, of above several ten times in the MnO, MgO, $K_2O$ and Ba, and of several times in the CaO and Sr are shown in the 3 year ginsengs. Differences of several hundred to thousand times in the $Al_2O_3$, of above several hundred times in the $TiO_2$, Cs and Y, and of several ten times in the MnO, MgO, $K_2O$ and Ba, and of several times in the $Na_2O$ are shown in the 4 year ginsengs. These relationships suggest that, regardless of the localities in the shale area, $Al_2O_3$ contents of the soils show big differences from those of the ginsengs. Regardless of the ages of ginsengs, comparisons with the overall average contents of each area show differences of several hundred times in the $Al_2O_3$, $TiO_2$, Cs and Tl and of several ten times in the MnO. These overall relationships suggest that the $Al_2O_3$, $TiO_2$, Cs and Tl contents of the soils are higher than those of the ginsengs, show big differences between two and low different contents are found in the MnO. In detail, differences of several hundred times in the Y, and ten times in the MgO and Sr, and of several times in the CaO, $Na_2O$, $K_2O$ in the case of shale area, are shown. These results suggest that the soils are higher than the ginsengs in the Y and significantly differences in Y, and moderately differences in the MgO and Sr, and low differences in the CaO, $Na_2O$ and $K_2O$ are shown between soils and ginsengs.

Different ages of the ginsengs were collected from the three soil areas, such as granite, phyllite and shale of Keumsan, with their field soils. Of the soils, phyllite and shale areas are high in the Ni, Cr, Co, Sc, V, As, Cu and Zn contents while the granite areas are low in the W, Pb, Th, U, Sn and Be contents. In the correlation coefficient of the soils, positive and negative relationships of the elements are mainly high in the shale and low in the granite area. Comparing between 2- and 3- year ginsengs, 2-year ginsengs are mainly high in most elements, especially for the granite and phyllite areas. In the regional comparisons among the same ages, the granite areas are mainly low and high in the shale area for the most of the elements. Comparisons among the parts of ginsengs suggest high contents in the most of the elements at the upper parts. In the comparisons between the top soils and ginseng compositions, top soils are mainly high and show similar increase/decrease trends between them. Following the transitional element contents, the granite area is best for the ginseng cultivation while , among the three areas, the shale area is worst.

This study is for geochemical relationships between ginseng and soil from three representative soil types from Keumsan, shale, phyllite and granite. In the weathered soils(avg.), shale area is high in the most of element, but low in the granite area. In the field soils(avg.), the shale area is mainly high, but low in the granite area and comparing with ages, most of elements are high in the 2 year soils, but low in the 4 year soils. In the host rocks(avg.), high average element contents are shown in the phyllite and shale areas. In the ginsengs, differences of the element contents with ages are not clear, but show high element contents in the 2 year ginsengs of the shale and phyllite areas, and low contents in the 4 year ginsengs of the granite area. In the relative ratios(weathered soil/field soil), most of elements from the shale area are high, above 1, suggesting high element contents in the weathered soils of the shale area relative to the granite and phyllite areas. In the relative ratios(weathered soil/host rock), most of elements Ewe above 1, suggesting the high element contents in the weathered soils relative to the host rocks. Relative ratios (soil/ginseng) of the element contents are generally several times to ten times. Among the ginsengs of different ages with the same area, the relative ratios are small in the Cu and Zn contents. Regardless of the areas, big differences of the relative ratios are found in the Co and small differences are in the Cu and Zn, which suggest that differences between soils and ginsengs are big in the Co contents and small in the Cu and Zn contents. Regardless of the ages, differences among relative ratios are small in granite area relative to the shale. area, which suggest more similarity of the granite soils with ginsengsrelativetotheshalearea.

Ginsengs(1-3 years old) from the Keumsan were analysed for the rare earth element(REE) contents and compared with their soils from the biotite granite(CR), phyllite(PH) and shale(SL) areas. In the soils, high REE contents and correlations were found in the SL. In the ginsengs, high element contents were shown in the SL. High correlations were found in the 3 year. In the upper parts, the 2 year of the GR was mainly high. Comparing with the same aged ginsengs, high elements were shown in the SL. Positive correlations were dominated and high correlations were shown in the 3 year ginsengs. In the root parts, the GR was high in the 2 year while the PH and SL were high in the 3 year. Comparing with the same ages, high elements were shown in the SL. High correlation relationships were found. Comparing between upper and root parts, the upper parts were mainly high, LREE showed big differences and relative ratios of the 2 year were mainly high. Comparing between soils and ginsengs, the soils were mainly high. Ratios between soils and root parts(soils/root parts) were higher than those of the upper parts. Ratios of the LREE showed big differences relative to those in the HREE and the ratios increased with ages. Overall results suggested that ginsengs of the SL were similar to those of soils and those of the PH showed big differences.
