The effect of extracting conditions on the content of inorganic compounds of red ginseng extract was studied with respect to the change in ethanolic concentration ranges of $0{\sim}90%$ and temperature of $70{\sim}100^{\circ}C$ during $1{\sim}5$ times of extraction. Each extraction time was taken 8 hours at given temperature. Little effect of temperature on inorganic compounds was observed, while higher ethanol concentrations, particularly higher than 70%, were resulted a significant decreased in their contents. The yield of inorganic compounds in water was shown 80% over after 3rd extraction, while content of crude ash was observed similar tendency and their contents were significant increased in water than in 70% ethanolic concentration. In the process of extraction with water, 1.55% of the potassium content was the highest value, and the smallest was 11ppm of the copper. But in the extraction ratio to raw mateirls, the highest ratio was 91.4% of the calcium, and smallest was 30.4.% of the magnesium.

Background: Red ginseng (RG) is processed from Panax ginseng via several methods including heat treatment, mild acid hydrolysis, and microbial conversion to transform the major ginsenosides into minor ginsenosides, which have greater pharmaceutical activities. During the fermentation process using microbial strains in a machine for making red ginseng, a change of composition occurs after heating. Therefore, we confirmed that fermentation had occurred using only microbial strains and evaluated the changes in the ginsenosides and their chemical composition. Methods: To confirm the fermentation by microbial strains, the fermented red ginseng was made with microbial strains (w-FRG) or without microbial strains (n-FRG), and the fermentation process was performed to tertiary fermentation. The changes in the ginsenoside composition of the self-manufactured FRG using the machine were evaluated using HPLC, and the 20 ginsenosides were analyzed. Additionally, we investigated changes of the reducing sugar and polyphenol contents during fermentation process. Results: In the fermentation process, ginsenosides Re, Rg1, and Rb1 decreased but ginsenosides Rh1, F2, Rg3, and Compound Y (C.Y) increased in primary FRG more than in the raw ginseng and RG. The content of phenolic compounds was high in FRG and the highest in the tertiary w-FRG. Moreover, the reducing sugar content was approximately three times higher in the tertiary w-FRG than in the other n-FRG. Conclusion: As the results indicate, we confirmed the changes in the ginsenoside content and the role of microbial strains in the fermentation process.

Background: Ginseng produced by hydroponics can be cultivated without using agricultural chemicals; thus, it can be used as a raw materials for functional foods, medicines, and cosmetics. This study aimed to determine the optimal harvesting time to obtain the highest levels of ginsenoside and ginseng, as this was not previously unknown. Methods and Results: One-year-old organic ginseng seedlings were transplanted and cultivated using hydroponics for 150 days in a venlo-type greenhouse, using ginseng nursery bed soil and a nutrient solution ($NO_3{^-}-N$; 6.165, P; 3.525, K; 5.625, Ca; 4.365, Mg; 5.085, S; $5.31mEq/{\ell}$). Ginsenoside content and fresh and dry weights were higher at 120 days after transplanting than at 30, 60, 90, and 150 days. Total ginsenoside content was 11.86 times higher in the leaf and stem than in the root at 120 days after transplanting. Ginsenosides F1, F2, F3, and F5 were detected in ginseng leaves and stems. These chemical compounds are known to be effective in altering skin properties, including whitening, anti-inflammation, and anti-aging. Conclusions: Optimal harvesting time for ginseng cultivated using hydroponics was 120 days after transplanting when the biomass and ginsenoside content were highest.

This study was conducted to find out the optimum composition of nursery soil for raising seedling of ginseng (Panax ginseng C. A. Meyer). Total 9 kinds of raw materials were used such as peat-moss, perlite, leaf mould, rice bran, gull's guano, castor-oil plant bark, palm bark, cow manure and chicken manure for optimum composition of nursery soil in ginseng. Occurrence of damping-off in ginseng was lowered about 50% in nursery soil type 1, 2 and 4 than in other types nursery soil in June, and occurrence rate of rusty root also lowest in nursery soil type 1. As the salinity of nursery soil increased, so did the occurrence of physiological disorder in ginseng seedling. The cause of salinity increasing in nursery soil has closely relation to $NO_3-N$, $P_2O_5$ and $Na^+$ content. Plant height, root length, diameter and weight were longer and heavier in nursery soil type 1 (mixing ratio of peat-moss, perlite and leaf mould was 50 : 20 : 30 based in volume) than in other types of nursery soil. So nursery soil type 1 was selected for raising seedling of ginseng. pH and electric conductivity (EC) of selected nursery soil type 1 was 5.55 and 0.13 dS/m. Contents of $NO_3-N$ and $P_2O_5$ were 21.0 and 40.0 mg/L, and $K^+$ 0.36, $Ca^{2+}$ 3.38, $Mg^{2+}$ 2.01 and $Na^+$ $0.09cmol^+/L$, respectively.

Healthy ginseng pudding was made with different doses of two gelling agents and stored at $37^{\circ}C$ for eight weeks. And then quality characteristics and palatability were measured. Sweetness and pH level increased in newly made ginseng puddings but decreased during storage. Acid taste decreased but increased during storage in A (pectin 0.2%+agar 0.6%). But it increased but subsequently decreased in B (agar 0.8%). Acidity in C (agar 1%) remained unchanged until six weeks but slightly increased at 8 weeks of storage. Texture increased in all specimens but subsequently decreased. Chromaticity value of L decreased in all specimens before increasing while the values of a and b increased and subsequently decreased. In texture examination, hardness and adhesion were higher in C (agar 1%) and lower in A (pectin 0.2%+agar 0.6%). There were no differences in elasticity among three specimens. Cohesion was higher in C (agar 1%) while it showed a similar level in A (pectin 0.2%+agar 0.6%) and B(agar 0.8%). Stickiness and chewiness were higher in C(agar 1%) but lower in A(Pectin 0.2%+agar 0.6%), compared with C(agar 1%) specimen. In sensory test, overall palatability was higher in A (Pectin 0.2%+agar 0.6%). In conclusion, ginseng pudding with 0.6% agar and 0.2% pectin exhibited better quality. And ginseng pudding has potential to be developed as healthy dessert considering ample physiological and functional properties.

The six phenolic-compound (ascorbic acid, maltol, esculetin,p-coumaric acid, cinnamic acid, and quercetin) contents of Panax ginseng c.A. Meyer were determined in this study. The results showed that the ascorbic acid, cinnamic acid, and esculetin contents of Panax ginseng C.A. Meyer are higher than those of the other ingredients. Among these compounds, ascorbic acid and cinnamic acid significantly inhibited LPS-induced nitric oxide production in the RAW 264.7 cells. Cinnamic acid also effectively inhibited the oxidative damages in the human neuroblastoma SH-SY5Y cells. Although this study examined the neuroprotective and anti-inflammatory activities using only one kind of cells, its results suggest that cinnarnic acid potently contributes to the neuroprotective and anti-inflammatory properties of Panax ginseng C.A. Meyer.

Background: Black ginseng (BG) is a type of Korean ginseng prepared by steaming and drying raw ginseng to improve the saponin content. This study examined the effects of BG on nonalcoholic fatty liver disease (NAFLD) in HepG2 cells and diet-induced obese mice. Methods: HepG2 cells were treated with free fatty acids to induce lipid accumulation before supplementation with BG. NAFLD-induced mice were fed different doses (0.5%, 1%, and 2%) of BG for 8 weeks. Results: BG significantly reduced lipid accumulation and expression of lipogenic genes, peroxisome proliferator-activated receptor gamma, CCAAT/enhancer-binding protein alpha, sterol regulatory element-binding protein-1c, and fatty acid synthase in HepG2 cells, and the livers of mice fed a 45% high-fat diet with 10% fructose in the drinking water (HFHF diet). BG supplementation caused a significant reduction in levels of aspartate aminotransferase and alanine aminotransferase, while antioxidant enzymes activities were significantly increased in 45% high-fat diet with 10% fructose in the drinking water diet-fed mice. Expression of proliferator-activated receptor alpha and carnitine palmitoyltransferase I were upregulated at the transcription and translation levels in both HepG2 cells and diet-induced obese mice. Furthermore, BG-induced phosphorylation of AMP-activated protein kinase and acetyl CoA carboxylase in both models, suggesting its role in AMP-activated protein kinase activation and the acetyl CoA carboxylase signaling pathway. Conclusion: Our results indicate that BG may be a potential therapeutic agent for the prevention of NAFLD.
