To compare and analyze the improvement effects of white ginseng extract, red ginseng extract, and black ginseng extract on cognitive dysfunction and memory impairment caused by scopolamine in rats. In the cognitive behavioral test, the tendency of the SCOP+B group to overcome the escape time delay induced by scopolamine administration was observed, unlike the SCOP group. The frequency on plat form was significantly increased in the group treated with ginseng extracts compared to the SCOP group. As a result of measuring the duration time on goal quadrant, the time spent in the quadrant was significantly increased in the SCOP+B group compared to the SCOP group. In the hippocampus, the SCOP-treated group significantly decreased the activity of AChE compared to the normal group, but the ginseng extract-treated groups significantly increased it compared to the SCOP group. After sacrificing the rats after the behavioral test, the expression of PSD95 protein in the excised brain was significantly decreased in the SCOP group compared to normal, but it was observed that the SCOP+R and SCOP+B groups were significantly increased compared to the SCOP group. CREB1 protein expression was significantly increased in the SCOP+R group, and the expression of Cdk5 was significantly increased in the SCOP+B group. Ginseng extracts significantly restored the memory damaged by scopolamine suggesting that red ginseng increased the expression of CREB1 and PSD95 proteins, and black ginseng increased the protein expression of Cdk5 and PSD95 to induce memory recovery.

Acetaminophen(APAP) is one of the most extensively used analgesics and antipyreics worldwide. In order to investigate preventive effects of white and red ginseng extracts, male ICR mice pretreated with white or red ginseng extracts(50 or 250 mg/kg/day, for 5 days, orally) before treatment with acetaminophen(800mg/kg, i.p, single dose). In an attempt to elucidate the possible mechanism of hepatoprotective effect, superoxide dismutase(SOD), catalase(CAT), hydroperoxide, malondialdehyde(MDA) contents were studied. In pretreatment with red ginseng extract(250 mg/kg), the activities of SOD, CAT were generally highest and the hydrogen peroxide content was lowest. The levels of MDA were significantly lower in white and red ginseng extract groups than those in the APAP groups. By treatment with ginseng extract, high content of hydrogen peroxide and increased lipid peroxidatiion level caused by APAP could be lowered. Also, ginseng extracts were found to increase antioxidative enzyme activity. Finally, the results suggest that the antioxidant effects of (white and red) ginseng extracts prevent oxidative damage by direct antioxidant effects involving SOD, CAT and increasing the ability to synthesize endogenous antioxidants. It was concluded that ginseng can protect against APAP intoxication through its antioxidant properties.

This study was conducted to provide basic information on ginseng saponin of dried ginseng radices. In order to achieve the proposed objective ginsenoside compositions of dried ginseng radices extract with 70% ethyl alcohol were examined by HPLC. The total saponin content, the sum of all ginsenosides, showed that Wild simulated ginseng (WSG), White fine ginseng (WFG), Skin White ginseng (SWG), and White ginseng (WG) stood at 2.510%, 1.643%, 0.587, and 0.429%, respectively. WSG in PPD/PPT ratio was highest at 3.190, WFG (1.934), WG (1.600), SWG (1.386) in order. In the content of ginsenoside Rb1, one of the marker compounds of ginseng, WSG (1.095%) showed the highest content, and WFG (0.527%), SWG (0.246%), WG (0.133%) in this order. The content of ginsenoside Rb1 of WSG (1.095%) was 4.5 times higher than SWG (0.246%). WSG (0.230%) showed the highest content in ginsenoside Rg1, a marker compounds of ginseng, followed by WFG (0.180%), SWG (0.141%) and WG (0.086%). The content of ginsenoside Rg1 of WSG (0.230%) was 1.6 times higher than SWG (0.141%).

Comparison of the physico-chemical characteristics were investigated among white (WG), fermented (FG) and red ginseng (RG) extracts. We observed maximum contents of extractable solids in FG, but viscosity was lower than other ginseng extracts. The contents of ash and crude protein of FG were higher than those of other ginseng extracts. The contents of carbohydrate were similar, but component Na and cruid lipids were maximum in RG. we extended our study on comparison of the calories among WG, FG and RG. We noticed that comparison of the calories among WG, FG and RG showed insignificant difference.

Ginseng (Panax ginseng Meyer) has been used as traditional herbal drug in Asian countries. Ginsenosides are major components having pharmacological and biological efficacy like anti-inflammatory, anti-diabetic and anti-tumor effects. To control the quality of the components in diverse ginseng products, we developed a new quantitative method using LC-MS/MS for 13 ginsenosides; Rb1, Rb2, Rc, Rd, Re, Rf, 20(S)-Rh1, 20(S)-Rh2, Rg1, 20(S)-Rg3, F1, F2, and compound K. This method was successfully validated for linearity, precision, and accuracy. This quantification method applied in four representative ginseng products; fresh ginseng powder, white ginseng powder, red ginseng extract powder, and red ginseng extract. Here the amounts of the 13 ginsenosides in the various type of ginseng samples could be analyzed simultaneously and expected to be suitable for quality control of ginseng products.

We aimed to compare the content of ginsenosides and the pharmacokinetics after the oral administration of four different ginseng products at a dose of 1 g/kg in rats. The four different ginseng products were fresh ginseng extract, red ginseng extract, white ginseng extract, and saponin enriched white ginseng extract prepared from the radix of Panax ginseng C.A. Meyer. The ginsenoside concentrations in the ginseng product and the rat plasma samples were determined using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Eight or nine ginsenosides of the 15 tested ginsenosides were detected; however, the content and total ginsenosides varied depending on the preparation method. Moreover, the content of triglycosylated ginsenosides was higher than that of diglycosylated ginsenosides, and deglycosylated ginsenosides were not present in any preparation. After the single oral administrations of four different ginseng products in rats, only four ginsenosides, such as 20(S)-ginsenosides Rb1 (GRb1), GRb2, GRc, and GRd, were detected in the rat plasma samples among the 15 ginsenosides tested. The plasma concentrations of GRb1, GRb2, GRc, and GRd were different depends on the preparation method but pharmacokinetic features of the four ginseng products were similar. In conclusion, a good correlation between the area under the concentration curve and the content of GRb1, GRb2, and GRc, but not GRd, in the ginseng products was identified and it might be the result of their higher content and intestinal biotransformation of the ginseng product.

Free sugars in various ginseng products, Korean and Russian Acanthopanaxes were analyzed by gas liquid chromatography. Ginseng products included Korean red ginseng, white ginseng with skin produced in Korea, Canada, and America, and extracts of red and white ginseng. ${\alpha}-\;and\;{\beta}-fructoses,\;{\alpha}-\;and\;{\beta}-glucoses$, galactose, sucrose, and ${\alpha}-\;and\;{\beta}-maltoses$ were identified in Korean and American white ginsengs with skin, and in Korean red ginseng. However ${\alpha}-\;and\;{\beta}-maltoses$ were not detected in Canadian white ginseng with skin. Total amount of sugars identified in white ginseng with skin was higher than that in red ginseng. ${\alpha}-\;and\;{\beta}-fructoses,\;{\alpha}-\;and\;{\beta}-glucoses$, galactose, sucrose and ${\alpha}-\;and\;{\beta}-maltoses$ were identified in red and white ginseng extracts. Fructose was a major sugar in red ginseng extract while it was sucrose in white ginseng extract. ${\alpha}-\;and\;{\beta}-glucoses$, galactose, sucrose and ${\alpha}-\;and\;{\beta}-maltoses$ were identified in Russian Acanthopanax, and their patterns were similar to that of ginseng, while ${\beta}-fructose,\;{\alpha}-\;and\;{\beta}-glucoses$ and sucrose were identified in Korean Acantopanax and total amount of sugars was only one third of that in Russian Acanthopanax.

The anti-Helicobacter pylori activity, cytotoxicity, and anti-inflammatory activity of white ginseng extract (WGE) were investigated in vitro in this study. The antimicrobial effects of WGE toward H. pylori strains 52 J99, SSI, and 51 were tested using the disk diffusion method. Among these H. pylori strains, H. pylori 52 was the most sensitive, having the largest inhibition zone (19 mm), followed by J99, SSI, and 51. The zone of inhibition due to WGE increased significantly with increasing dosage. The cytotoxicity of WGE toward the human cancer cell lines A-549 (human lung carcinoma), HEC-1-B (human endometrial adenocarcinoma), HeLa (human uterin adenocarcinoma), and SW-156 (human kidney carcinoma) was measured using the 3-(4,5-dimethylthizol-2-yl)-2,5-diphenylate-tetrazolium bromide (MTT) assay. WGE exhibited an inhibitory effect on cell growth at 2.0 mg/mL for all tumor cell lines. An analysis of anti-inflammatory activity using the RAW 264.7 cell line showed that the inhibition of nitric oxide (NO) production increased as the WGE content increased. These results demonstrate the potential of WGE to be used as a health-promoting substance.
