A study was performed to compare the anticancer effects of Korean and Chinese red ginseng roots. The whole crude extracts or chloroform, methanol and acetone fractions of the crude extracts were added in the culture medium of three cancer cell lines, a mouse leukemia cell line ($P_{388}$), a human colon carcinoma cell line (HT-29) and a human rectal carcinoma cell line (HRT-18), to screen the growth inhibition effects. The results are summarized as follows : 1. Crude extracts of both Korean and Chinese red ginseng roots inhibited the proliferation of all the three cancer cell lines tested in a dose dependent manner. However, the growth inhibition effects of Korean red ginseng extracts were significantly greater than that of Chinese red ginseng. 2. An acetone fraction showed the greatest antiproliferative effects among the 11'hole crude extracts, chloroform, methanol and acetone fractions of the crude extracts. 3. These results suggest that the active antiproliferative components of the crude extracts are present mostly in the acetone fraction.

Three unknown ninhydrin positive substances (UK-I, UK-II and UK-III) were detected with an amino acid analyzer in a water extract of Korean red ginseng. One of them (UK-II) was isolated and determined to be maltulosyl arginine (Arg-Fru-Glc) on the basis of chemical and spectroscopic evidence. Another one (VK-III) was identified as Arg-Fru. Maltulosyl arginine, but not Arg-Fru, is a newly identified amino acid derivative. The Korean red ginseng was shown to contain more amount of maltulosyl arginine than the white ginseng. Maltulosyl arginine was found to be produced by the Mallard reaction of maltose with arginine during the heating process involved in preparation of the red ginseng. Maltulosyl arginine was found to inhibit maltase activity. Based on these results, the physiological significance of this new compound is discussed.

This study aims to analyze the differences of ginseng product consumers and segment Korean fresh ginseng and red ginseng root markets based on attributes for the purchase. As a result of analyzing survey data, the red ginseng root consumers had different aspects from fresh ginseng consumers. According to the result of cluster analysis, the fresh ginseng consumers were subdivided into three segments (safety-oriented consumption cluster, label centered consumption cluster, and high involvement consumption cluster), while the red ginseng root consumers were subdivided into four segments (convenience-oriented consumption cluster, high involvement consumption cluster, raw material's safety-oriented cluster, and raw material's information importance cluster). ANOVA and Crosstab were conducted to investigate characteristics of each cluster.

Effects of Korean red ginseng (KG) and western ginseng (WG) on body temperature, pulse rate, clinical symptoms and hematological changes in human were studied after administration p.o. with Korean red ginseng and western ginseng for 10-days. KG was more effective in keeping homeostsis in than western ginseng in the changes of body temperature and pulse rate. KG was more effective in low body temperature and SOEVMIN (소음인), while inducing tachycardia especially in SOYANGIN (소양인) and TAEEUMIN (태음인). WG tended to drop temperature abruptly and also descended pulse rate with greater range than KG. KG and WG could cause side effects such as headache and gastrointestinal syndromes and induce hypertension or hypotension abruptly in specific constitutions. However, KG and WG did not cause abnormal changes in urinalysis and hematology.

Background: Red-skin root disease has seriously decreased the quality and production of Panax ginseng (ginseng). Methods: To explore the disease's origin, comparative analysis was performed in different parts of the plant, particularly the epidermis, cortex, and/or fibrous roots of 5-yr-old healthy and diseased red-skin ginseng. The inorganic element composition, phenolic compound concentration, reactive oxidation system, antioxidant concentrations such as ascorbate and glutathione, activities of enzymes related to phenolic metabolism and oxidation, and antioxidative system particularly the ascorbate-glutathione cycle were examined using conventional methods. Results: Aluminum (Al), iron (Fe), magnesium, and phosphorus were increased, whereas manganese was unchanged and calcium was decreased in the epidermis and fibrous root of red-skin ginseng, which also contained higher levels of phenolic compounds, higher activities of the phenolic compound-synthesizing enzyme phenylalanine ammonia-lyase and the phenolic compound oxidation-related enzymes guaiacol peroxidase and polyphenoloxidase. As the substrate of guaiacol peroxidase, higher levels of $H_2O_2$ and correspondingly higher activities of superoxide dismutase and catalase were found in red-skin ginseng. Increased levels of ascorbate and glutathione; increased activities of $\text\tiny L$-galactose 1-dehydrogenase, ascorbate peroxidase, ascorbic acid oxidase, and glutathione reductase; and lower activities of dehydroascorbate reductase, monodehydroascorbate reductase, and glutathione peroxidase were found in red-skin ginseng. Glutathione-S-transferase activity remained constant. Conclusion: Hence, higher element accumulation, particularly Al and Fe, activated multiple enzymes related to accumulation of phenolic compounds and their oxidation. This might contribute to red-skin symptoms in ginseng. It is proposed that antioxidant and antioxidative enzymes, especially those involved in ascorbate-glutathione cycles, are activated to protect against phenolic compound oxidation.

The Chinese ginseng roots were collected at twelve places of Jilin Province and two places of Liaoning Province in China and their appearances were compared with those of the Korean ginseng roots. The color of the most of the Chinese red ginseng was brown or dark brown and the color of many of the Chinese dried ginseng was pale yellow and the root-age of the most of the Chinese red ginseng as well as the Chinese dried ginseng was evaluated five or six year regardless of the collection places, so it cannot be easily concluded that the color and the root-age of the Chinese ginseng roots are different from those of the Korean ginseng roots. However the rhizomes and the lateral roots of the Chinese ginseng roots were poorly developed and many of them did not have either rhizome or lateral roots. Moreover the rhizomes of the Chinese red ginseng as well as the Chinese dried ginseng were much more easily removed than those of the Korean red ginseng and the Korean white ginseng. Therefore it is thought that the development status of the rhizome and the lateral roots of the Chinese ginseng roots are quite different from those of the Korean ginseng roots.

To reduce the production cost of Lactobacillus, discarded red ginseng starch was collected from a factory of red ginseng extract in order to develop the Lactobacillus culture medium. According to the analysis of the gensenoside composition of red ginseng starch, the total gensenoside content of starch was 2.73 mg/g, and the gensenoside $Rb_1$, $Rb_2$ and $Rg_3$ contents were 0.1, 0.29 and 0.52 mg/g, respectively. For the preparation of the liquid media, red ginseng starch was added at rates of 0, 5, 10 and 20%. Further, Lactobacillus plantarum 15357 and Leuconostoc mesenteroides sub sp. strains were then inoculated to these prepared broths. With the red ginseng starch medium, the growth rates ($1.42{\times}10^7$ and $2.96{\times}10^{10}$ CFU/mL) and the final cell concentrations were higher than the MM medium ($1.0{\times}10^7$ CFU/mL). The optimal concentration of red ginseng starch and yeast extract as a medium were 20% and 10 g/L, respectively. Under these conditions, the cell mass of L. plantarum 15357 and L. mesenteroides sub sp. reached $5.11{\times}10^{10}$ and $8.17{\times}10^{10}$ CFU/mL. These results show a great possibility for the utilization of red ginseng starch as economic medium sources in the production of cell mass of lactic acid bacteria. This is the first trial of development of economic LAB growth medium using discarded red ginseng starch.

Background: The reports about valuable oligosaccharides in ginseng are quite limited. There is an urgent need to develop a practical procedure to detect and analyze ginseng oligosaccharides. Methods: The oligosaccharide extracts from ginseng were permethylated by solid-phase methylation method and then were analyzed by ultra-high-performance liquid chromatography-Q-Orbitrap/MS. The sequence, linkage, and configuration information of oligosaccharides were determined by using accurate m/z value and tandem mass information. Several standard references were used to further confirm the identification. The oligosaccharide composition in white ginseng and red ginseng was compared using a multivariate statistical analysis method. Results: The nonreducing oligosaccharide erlose among 12 oligosaccharides identified was reported for the first time in ginseng. In the comparison of the oligosaccharide extracts from white ginseng and red ginseng, a clear separation was observed in the partial least squares-discriminate analysis score plot, indicating the sugar differences in these two kinds of ginseng samples. The glycans with variable importance in the projection value large than 1.0 were considered to contribute most to the classification. The contents of oligosaccharides in red ginseng were lower than those in white ginseng, and the contents of maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, maltooctaose, maltononaose, sucrose, and erlose decreased significantly (p < 0.05) in red ginseng. Conclusion: A solid-phase methylation method combined with liquid chromatography-tandem mass spectrometry was successfully applied to analyze the oligosaccharides in ginseng extracts, which provides the possibility for holistic evaluation of ginseng oligosaccharides. The comparison of oligosaccharide composition of white ginseng and red ginseng could help understand the differences in pharmacological activities between these two kinds of ginseng samples from the perspective of glycans.

This study was conducted to develop a real-time internal quality evaluation technique for Korean red ginseng using NIR spectroscopy while they were moving to be graded. Internal qualities of Korean red ginseng were defined by color, amount of white core and cavity in the red ginseng. To evaluate the internal quality, PLS (Partial Least Square) model was developed. Spectrum saturation can be occurred when most red ginseng has a sound internal quality expressed by higher light transmittance ratio, but that could not found in the ginseng of internal white core under the same light situation. And, if spectrum saturation is obtained, it is hard to identify the exact information of internal quality. In order to evaluate of the internal quality regardless of having internal normal core or white core, an integral time controlled method was used to obtain traditional spectrum. This procedure was applied in real-time process when red ginseng was moving to be graded in the line. Among the 450 samples including 223 internal normal ginsengs and 227 internal white core ginsengs, 315 ginsengs (70%) were used to develop a calibration model and 135 ginsengs were spent to validate the model. The result of quality evaluation by the model was very good showing SEP and bias were 0.3573 and 0.0310, respectively, and the accuracy was 95.6%.

Codium fragile is an edible seaweed in Asian countries that has been used as a thrombolytic, anticoagulant, antioxidant, anti-inflammatory, and immune-stimulatory agent. Ginseng has also been known to maintain immune homeostasis and to regulate the immune system via enhancing resistance to diseases and microorganisms. In this study, anionic macromolecules extracted from C. fragile (CFAM) were orally administered with red ginseng extract (100 mg/kg body weight) to cyclophosphamide-induced immunosuppressed male BALB/c mice to investigate the immune-enhancing cooperative effect of Codium fragile and red ginseng. Our results showed that supplementing CFAM with red ginseng extract significantly increased spleen index, T- and B-cell proliferation, NK cell activity, and splenic lymphocyte immune-associated gene expression compared to those with red ginseng alone, even though a high concentration of CFAM with red ginseng decreased immune biomarkers. These results suggest that CFAM can be used as a co-stimulant to enhance health and immunity in immunosuppressed conditions.
