Background: Temperature is an essential condition in red ginseng processing. The pharmacological activities of red ginseng under different steam temperatures are significantly different. Methods: In this study, an ultrahigh-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry was developed to distinguish the red ginseng products that were steamed at high and low temperatures. Multivariate statistical analyses such as principal component analysis and supervised orthogonal partial least squared discrimination analysis were used to determine the influential components of the different samples. Results: The results showed that different steamed red ginseng samples can be identified, and the characteristic components were 20-gluco-ginsenoside Rf, ginsenoside Re, ginsenoside Rg1, and malonyl-ginsenoside Rb1 in red ginseng steamed at low temperature. Meanwhile, the characteristic components in red ginseng steamed at high temperature were 20R-ginsenoside Rs3 and ginsenoside Rs4. Polar ginsenosides were abundant in red ginseng steamed at low temperature, whereas higher levels of less polar ginsenosides were detected in red ginseng steamed at high temperature. Conclusion: This study makes the first time that differences between red ginseng steamed under different temperatures and their ginsenosides transformation have been observed systematically at the chemistry level. The results suggested that the identified chemical markers can be used to illustrate the transformation of ginsenosides in red ginseng processing.

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.

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.

This study was devised to observe the inhibitory effects of 3 kinds of petroleum ether extracts (percolation by petroleum ether) from Korean red ginseng, Chinese red ginseng and American white ginseng on a lipolytic action of Toxohormone-L which has been known as lipolytic and anorexigenic factors. Toxohormone-L was obtained by partial purification of the ascites fluid from mice which had been Inoculated with sarcoma-180. The yields of petroleum ether extract from Korean red ginseng, Chinese red ginseng and American white ginseng were 0.64, 0.47 and 0.58 and respectively, indicating that the yield of Korean red ginseng was the highest. In vitro, at the concentration of 2 mg /ml, the inhibition rate of lipolysis by the petroleum ether extract of Korean red ginseng, Chinese red ginseng and American white ginseng were 55.1, 50.0 and 44.9% respectively, and the total inhibitory activity per gram of ginseng material were 18, 12 and 13 unit respectively, indicating that the Korean red ginseng was the most effective in the inhibition of the lipolysis.

Red ginseng is a medicinal herb widely used in East-Asia for a long time. Recently there have been a lot of studies about the effect of red ginseng on the immune responses. We investigated the differences between Korean red ginseng and Chinese red ginseng in the lymphocyte proliferation and cytokine production. The rats were divided into 3 groups, KRG(Korean Red Ginseng) group, CRG(Chinese Red Ginseng) group, and the Control group. Experimental groups were administered with Korean and Chinese red ginsengs for three months respectively. Then we obtained the lymphatic cells from spleen and compared the ability of KRG on the lymphocyte proliferation and the cytokine production after mitogen-stimulated culture to CRG. The proliferation of lymphocyte and level of $IL-1{\alpha}$ were significantly increased only in KRG group. There were significant increases in the level of $INF-{\gamma}$ in both KRG and CRG groups. There were no significant differences in the level of IL-2 and $TNF-{\alpha}$. These results indicate that KRG can induce infection-relevant immune responses much faster and higher than CRG. Furthermore, functional activation of CD8+ T-cell may be activated by red ginsengs.

In order to compare the physical property of the rhizome of the Korean ginseng with the Chinese ginseng, the break intensity of the ginseng rhizome was measured using a rheometer (FVDOH RHEO METER, Rheotech Co.). The intensities for the Korean red ginseng were 10.0$\pm$ 2.1 kg/cm2(n=72), while the intensities for the Chinese red ginseng were 4.0$\pm$2.4 kg/cm2(n=142) which were significantly lower than those for the Korean red ginseng at 1% level. The intensities for the Korean white ginseng were 9.9$\pm$2.0 kg/cm2 (n=97), while the intensities for the Chinese deied ginseng were 4.5$\pm$2.7 kg/cm2(n=138) which were significantly lower than those for the Korean white ginseng at 1% level. These results suggest that the rhizome of the Chinese ginseng might be much more easily broken than the rhizome of the Korean ginseng. Conclusively the break intensity of the ginseng rhizome is thought to be useful for differentiating the Chinese ginseng with the Korean ginseng.

In order to screen out indicators for the discrimination of ginseng habitat, some physical and chemical characteristics of Korean red ginsengs (94 kinds) and Chinese red ginsengs (50 kinds) were analyzed by using a rheometer, an electronic nose system, a combined technique of solid phase micro-extraction (SPME) and gas chromatograph equipped with an electron capture detector (GC/ECD), an X-ray fluorescence spectrometer (XRF), an inductively coupled plasma mass spectrometer (ICP/MS), a near infrared spectrometer (NIRs) and high performance liquid chromatography equipped with evaporative light scattering detector (HPLC/ELSD). The results are summarized as follows: (i) The rhizome strengths of Korean red ginsengs were significantly higher than those of Chinese red ginsengs. (ii) The electronic nose patterns of Korean red ginsengs were significantly different from those of Chinese red ginsengs. (iii) Some unidentified peaks were detected not in the headspace of Korean red ginsengs but in the headspace of Chinese red ginsengs when the headspace volatiles prepared by the SPME technique were analyzed by GC/ECD. (iv) Either the content ratios of K to Ca or Mn to Fe were significantly different between Korean red ginsengs and Chinese red ginsengs. (v) The reflectance ratios of NIRs wavenumbers such as $904\;cm^{-1}\;to\;1088\;cm^{-1}$ for Korean red ginsengs were significantly different from those for Chinese red ginsengs. (vi) The content ratios of ginsenoside-Rg to ginsenoside-Re of Korean red ginsengs were significantly higher than those of Chinese red ginsengs. These results indicate that the rhizome strength, the electronic nose pattern, the occurrence of ECD-sensitive headspace volatile components, the content ratios of K to Ca and Mn to Fe, the NIRs pattern and the content ratio of ginsenoside-Rg to -Re may be indicators for the discrimination of ginseng habitat.

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.

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.
