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.

This study was carried out to determine the differences of essential oil components among Korean, Chinese and Japanese red ginseng, and Korean white ginseng (Panax ginseng C.A Mayer) , American and Canadian ginseng (P. Quinquefolium), and sanchi ginseng (P notoginseng). The steam distilled oils of these ginsengs were analyzed by GC and GC-MS, and 22 sesquiterpenes, 8 sesquiterpene alcohols, 8 monoterpenes, 5 aldehydes, 4 esters, 3 acids, 2 alcohols and 5 miscellaneous components were identified. The major oil components of Korean, Chinese and Japanese red ginseng were $\beta$-panasinsene, $\beta$-caryophyllene, $\alpha$-panasinsene, $\alpha$-neoclovene, selina-4,11-diane, bicyclo-ger-macrene and spathulenol. The contents of $\beta$-panasinsene, $\alpha$-neoclovene, $\alpha$-basabolene and spathulenol were higher in Korean red ginseng than Chinese and Japanese red ginseng. The contents of $\alpha$-cubebene, selina-4,11-diene and ledol were higher in Chinese red ginseng than Korean and Japanese red ginseng, but those of selina-4,11-diene and spathulenol were lower in Japanese red ginseng than Korean or Chinese red ginseng. On the other hand, the GC patterns of the oils from American, Canadian and sanchi ginseng were different from that of Korean white ginseng.

Chemical studies of nitrogen compounds of Panax ginseng seem relatively rare, Probably due to the isolation difficulties, subsequently the investigations of biological activities are little. The experimental conditions were established for highly complete extraction of peptides (basic, acidic and neutral) from Panax ginseng. This task was achieved by applying the follow isolation procedure: 1 , the sequential extraction with water, 0.1% TFA in 20% acetonitril and buffer pH 6.5 (water-pyridine-acetic acid 100:3:900) : 2, fractionation by ultrafiltration : 3, n-butanol extraction 4, cation- and anion-exchange chromatography : 5, chromato-electrophoresis. The comparison of red ginseng (xylem Sl pith part) and red ginseng inside white (xylem Sc pith part) was also provided. To analyze the peptide mixture the chromato-electrophoresis method of separation was applied. Optimal conditions for peptides mapping of sample were explored. Our experiments revealed the quantitative difference of peptide between xylem & pith and phloem & cortex part. We have also found the qualitative difference in the composition of polypeptides between normal red ginseng (xylem Sc pith part) and red ginseng inside-white (xylem St pith part)

Total polysaccharide contents in Panax ginseng roots were evaluated by a spectrophotometry, utilizing the complex formation of ginseng polysaccharide with alcian blue dye in 50 mM ammonium biphosphate, pH 4.2. The total polysaccharide content in red ginseng was about three times higher than that in fresh ginseng when both were extracted with water, and was increased about two times when red ginseng was extracted with an alkaline solution. The determination of total polysaccharide in various parts of ginseng revealed that main roots contained the component more than fine roots. Fresh ginseng sections stained by the dye showed polysaccharide mainly found in cortex and cambium but not in epidermis. Pattern-analysis on total and acidic polysaccharides from fresh and red ginsengs exhibited that the chemical compositions of the polysaccharides extracted from both ginsengs quite differed from each other.

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.

한국백삼 및 홍삼에서 조다당체 획분을 분리하여 이의 이화학적 성질을 검토하였다. 분리된 조다당체 획분중 백삼에서 얻어진 회분은 95.1%의 glucose를 함유하고 있었고 홍삼에서 분리된 획분은 89.9%의 glucose를 함유하고 있었다. 홍삼에서 분리된 조다당체 획분의 양은 15.1%이었고 백삼에서 분리된 조다당체 획분의 양은 9.6%이었다 한편 홍삼에 함유된 산성 다당체의 함량은 4.3%이었고 백삼에 함유된 산성 다당체의 함량은 2.5%이었다. 조다당체 획분의 주요한 무기물 분석 결과 Na과 Ca은 백삼 및 홍삼에서 모두 높게 나타났으나 Cu, Zn, Fe, Mg 등의 무기물은 홍삼보다 백삼의 조다당체 획분에서 현저하게 높은 경향이었다.

Effects of red ginseng acidic polysaccharides (RGAP) on immune system were studied. The proliferation of spleen cells was induced by RGAP treatment per se. Cotreatment of lipopolysaccharide $(100\;{\mu}g/ml)$ or concanavalin A $(1\;{\mu}g/ml)$ with RGAP further stimulated the spleen cell proliferation. BALB/c mice treated with RGAP showed a slight splenic hyperplasia and increased antibody forming cell response to sheep red blood cells. Flow cytometry analysis revealed an influx of macrophages in the mice treated with RGAP.

Background: The chemical constituents of Panax ginseng are changed by processing methods such as steaming or sun drying. In the present study, the chemical change of Panax ginseng induced by steaming was monitored in situ. Methods: Samples were separated from the same ginseng root by incision during the steaming process, for in situ monitoring. Sampling was sequentially performed in three stages; FG (fresh ginseng) ${\rightarrow}$ SG (steamed ginseng) ${\rightarrow}$ RG (red ginseng) and 60 samples were prepared and freeze dried. The samples were then analyzed to determine 43 constituents among three stages of P. ginseng. Results: The results showed that six malonyl-ginsenoside (Rg1, Rb1, Rb3, Rc, Rd, Rb2) and 15 amino acids were decreased in concentration during the steaming process. In contrast, ginsenoside-Rh1, 20(S)-Rg2, 20(S, R)-Rg3 and Maillard reaction product such as AF (arginine-fructose), AFG (arginine-fructose-glucose), and maltol were newly generated or their concentrations were increased. Conclusion: This study elucidates the dynamic changes in the chemical components of P. ginseng when the steaming process was induced. These results are thought to be helpful for quality control and standardization of herbal drugs using P. ginseng and they also provide a scientific basis for pharmacological research of processed ginseng (Red ginseng).

Background: Skin microbiota is important for maintenance of skin homeostasis; however, its disturbance may cause an increase in pathogenic microorganisms. Therefore, we aimed to develop a red ginseng formulation that can selectively promote beneficial bacteria. Methods: The effects of red ginseng formulation on microorganism growth were analyzed by comparing the growth rates of Staphylococcus aureus, S. epidermidis, and Cutibacterium acnes. Various preservatives mixed with red ginseng formulation were evaluated to determine the ideal composition for selective growth promotion of S. epidermidis. Red ginseng formulation with selected preservative was loaded into a biocompatible polymer mixture and applied to the faces of 20 female subjects in the clinical trial to observe changes in the skin microbiome. Results: Red ginseng formulation promoted the growth of S. aureus and S. epidermidis compared to fructooligosaccharide. When 1,2-hexanediol was applied with red ginseng formulation, only S. epidermidis showed selective growth. The analysis of the release rates of ginsenoside-Rg1 and -Re revealed that the exact content of Pluronic F-127 was around 11%. The application of hydrogel resulted in a decrease in C. acnes in all subjects. In subjects with low levels of S. epidermidis, the distribution of S. epidermidis was significantly increased with the application of hydrogel formulation and total microbial species of subjects decreased by 50% during the clinical trial. Conclusion: We confirmed that red ginseng formulation with 1,2-hexanediol can help maintain skin homeostasis through improvement of skin microbiome.
