        To study on antioxidant effects in the liver of 40-week-old mouse, the sample were orally pretreated 5mg/kg/day for 5 days with red ginseng saponin components(total saponin, protopanaxadiol saponin, protopanaxatriol saponin, ginsenoside-Rd, ginsenoside-Re, compound-K) for 5 days. The ability of saponin to protect the mouse liver from oxidative damage was examined by determining the activity of superoxide dismutase(SOD), glutathione peroxidase(GPx) and the contents of glutathione, the level of malondialdehyde, The only protopanaxadiol among the ginseng saponin fractions was significantly increased the hepatic SOD activity(p<0.01). The red ginseng saponin induced a slight increase of GPx activity, especially ginsenoside Rd, compound K and protopanaxatriol treatments significantly increased its activity. The content of glutathione was significantly increased by total saponin, protopanaxadiol and ginsenoside Rd(p<0.01), but the oxidized glutathione level was lowered in all the red ginseng saponin. Finally, the level of malondialdehyde was significantly decreased by ginsenoside Rd and protopanaxadiol. In conclusion, protopanaxadiol and ginsenoside Rd among the saponin fraction were especially increased in the activity of hepatic antioxidative enzyme and decreased the lipid peroxidation that was expressed in term of MDA formation. This comprehensive antioxidant effects of red ginseng saponin seems to be by a certain action of saponin other than a direct antioxidant action.

        Background: Since the revised Ginseng Industrial Act was passed, ginseng sprouts have become a new medicinal vegetable for which there is high consumer demand. However, the existing amount of research and data on ginseng production has not kept pace with this changed reality. Methods and Results: In this study we analyzed the changes in the amounts of ginsenosides in different parts of growing ginseng sprouts during the period from when organic seedlings were planted in nursery soil until 8 weeks of cultivation had elapsed, which was when the leaves hardened. In the leaves, ginsenoside content increased 1.62 times with the panaxadiol (PD) system and 1.31 - 1.56 times with the panaxatriol (PT) system from 7 to 56 days after transplantation. During the same period, the total ginsenoside content of the stems decreased by 0.66 - 0.91 times, and those of the roots increased until the 21st day, and then underwent steep declines. The effect of fermented press cake extract (FPCE) and tap water (TP) on the total amount of ginsenoside per plant were similar, and could be represented with the equations y = 1.4330 + 0.2262x - 0.0008x2 and y = 0.9555 + 0.2997x - 0.0031x2 in which y = ginsenoside content x = amount of and on the total amounts of FPCE or TP, respectively after 26.4 days, however, the difference between ginsenoside content with FPCE and TP widened. Conclusions: These results suggested that the amounts of ginsenosides in different parts of ginseng varied with the cultivation period and nutrient supply. These findings also provide fundamental data on the distribution of ginsenosides among plant parts for 2- year-old ginseng plants in the early- growth stage.

        Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside- Re content of ginseng roots, which are used as food, medicine, or cosmetic materials. Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per 1.62㎡ ranged from 43.4 to 61.4, while the weight of berries per 1.62㎡ was the greatest when they were collected 49 days after flowering. The root fresh weight per 1.62㎡ was increased by 0.21 - 1.00 ㎏ compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering. Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.

        Background: In Korea, 6-year-old ginseng root is economically more important than 4 or 5-year-old roots. In general, the root age is determined by counting the number of stem vestiges. However, this method does not accurately estimate ginseng root age. Methods and Results: In this study, the stem vestige counting method was used to survey a total of 18,395 fresh ginsengs cultured in 2014, and 2015, to determine the accuracy of this method. The proportion of 6-year-old roots, with more than four stem vestiges, was 46.1% in 2014. For the cultivar Chunpoong cultivated in Eumseong and Goesan countries in 2015, the proportion of more than four stem vestiges was 55.9%, and 43.5%, respectively. The proportion of more than four stem vestiges for the Gumpoong cultivated in Eumseong and Yangpyeong countries was 67.0%, and 35.1%, respectively, whereas that for the cultivar Yunpoong was 36.0% and 61.0%, respectively. Moreover, it was confirmed that differences in the levels of Rg1 will enable root age determination. Conclusions: Root age determination by the stem vestige test was found to differ depending on the environmental and cultivation conditions. To determine the age of ginseng roots, a comprehensive method, such as counting stem vestiges and evaluating differences in ginsenoside levels, should be applied.

        Background : While the anti-inflammatory effects of 20 (S)-ginsenoside Rg3 (Rg3) have been studied, it remains unclear how Rg3 regulates lipid metabolism in inflammatory macrophages. Thus, in this study, we characterized some eicosanoids related to the anti-inflammatory effects of 20 (S)-ginsenoside Rg3 in murine macrophages. Methods and Results : UPLC-MS/MS was used to profile various eicosanoids from RAW264.7 cells treated with lipopolysaccharide (LPS) and Rg3. The profiling data were statistically analyzed by principal component analysis, hierarchical clustering analysis and analysis of variance. The anti-inflammatory effect of Rg3 was validated by assessing the levels of nitric oxide, tumor necrosis factor-α, and interleukin-6 in the activated macrophages treated with Rg3. A total of 69 eicosanoids were analyzed in RAW264.7 cells. Principal component and hierarchical cluster analyses differentiated control cells from cells treated with LPS, Rg3, or LPS + Rg3 for 12 or 24 h. Furthermore, some differentially regulated compounds were found between macrophages treated with LPS for 24 h and those treated with LPS + Rg3 for 24 h. Conclusion : Rg3 alters eicosanoid metabolism in activated macrophages treated with LPS. Furthermore, we identified several eicosanoids correlated with the anti-inflammatory activity of Rg3.
