Background: Fermented black ginseng (FBG) is produced through several cycles of steam treatment of raw ginseng, at which point its color turns black. During this process, the original ginsenoside components of raw ginseng (e.g., Re, Rg1, Rb1, Rc, and Rb2) are altered, and less-polar ginsenosides are generated (e.g., Rg3, Rg5, Rk1, and Rh4). The aim of this study was to determine the effect of FBG on wound healing. Methods: The effects of FBG on tube formation and on scratch wound healing were measured using human umbilical vein endothelial cells (HUVECs) and HaCaT cells, respectively. Protein phosphorylation of mitogen-activated protein kinase was evaluated via Western blotting. Finally, the wound-healing effects of FBG were assessed using an experimental cutaneous wounds model in mice. Results and Conclusion: The results showed that FBG enhanced the tube formation in HUVECs and migration in HaCaT cells. Western blot analysis revealed that FBG stimulated the phosphorylation of p38 and extracellular signal-regulated kinase in HaCaT cells. Moreover, mice treated with $25{\mu}g/mL$ of FBG exhibited faster wound closure than the control mice did in the experimental cutaneous wounds model in mice.

This study was conducted to investigate changes in composition of ginsenosides and color of processed ginsengs prepared by different steaming-drying times. Processed ginsengs were prepared from white ginseng with skin by 9-time repeated steaming at $96^{\circ}C$ for 3 hours and followed by hot air-drying at $50^{\circ}C$ for 24 hours. As the times of steaming processes increased, lightness (L value) decreased and redness (a value) increased in color of ginseng powders. Crude saponin contents and ginsenosides compositions in processed ginsengs prepared by different steaming-drying times were investigated using the HPLC method, respecively. Crude saponin contents according to increasing steaming-drying times decreased in some degree. In the case of major ginsenosides, the contents of $Rb_1$, $Rb_2$, Rc, Rd, Rf, Re, $RG_1$, Re were decreased with increase in steamimg times, but those of $Rh_1$, $Rg_3$, $Rk_1$ were increased after especially 3 times of steaming processes. Interestingly, in black ginseng were prepared by 9 times steaming processes, the content of ginsenoside $Rg_3$ was 8.20 mg/g, approximately 18 times higher than that (0.46 mg/g) in red ginseng. In addition, the ratio of the protopanaxadiol group and protopanaxatiol group (PD/PT) were increased from 1.9 to 8.4 due to increasing times of steamming process.

두뇌기능을 활성화시킬 수 있는 새로운 기능성 김치를 개발하기 위하여 다양한 농도의 흑삼추출물을 첨가한 배추김치를 제조한 후 $4^{\circ}C$에 30일간 저장하면서 경시적으로 김치의 물리화학적 생물학적 관능적 품질을 측정하였다. 0.5~5% 흑삼추출물을 첨가한 김치의 색도를 측정한 결과, 대조구보다 L 값은 감소하고 a 값과 b 값은 증가하여 김치의 색은 암갈색~흑색을 나타내었다. 1~5%의 흑삼추출물을 첨가한 김치는 대조구보다 pH 감소 및 산도 증가가 늦게 나타났고, 경도의 감소 경향도 낮았으며 젖산균 및 효모 증가도 더디게 나타났다. Acetylcholinesterase 활성 저해정도를 측정하였을 때, 흑삼처리구는 대조구보다 약 2배 정도 높은 저해도를 나타내었으며 흑삼의 첨가 농도가 높을수록 저해 정도가 높았다. 김치의 최적 숙성 적기를 전후하여 관능검사를 실시한 결과, 1~3% 흑삼처리구는 흑삼농도가 높을수록 관능특성이 높았으나, 5% 흑삼처리구는 김치에서 흑삼의 맛과 향이 강하여 관능특성이 대조구보다 낮았다. 김치를 제조할 때에 흑삼추출물을 첨가하면 처리농도에 비례하여 김치의 가식기간이 약 15일 정도 연장되었다. 따라서 두뇌기능활성화 효과가 있는 김치를 제조할 때에는 3%의 흑삼추출물을 첨가하는 것이 가장 효율적인 것으로 사료되었다.

Background: Ginseng (Panax ginseng) is a widely used traditional herbal supplement that possesses various health-enhancing efficacies. Various ginseng products are available in market, especially in the Korean peninsula, in the form of drinks, tablets, and capsules. The different ginseng types include the traditional red ginseng extract (RGE), white ginseng, and black red ginseng extract (BRGE). Their fermented and enzyme-treated products are also available. Different treatment regimens alter the bioavailability of certain compounds present in the respective ginseng extracts. Therefore, in this study, we aimed to compare the antioxidant and immune-stimulating activities of RGE, BRGE, and fermented red ginseng extract (FRGE). Methods: We used an acetaminophen-induced oxidative stress model for investigating the reduction of oxidative stress by RGE, BRGE, and FRGE in Sprague Dawley rats. A cyclophosphamide-induced immunosuppression model was used to evaluate the immune-stimulating activities of these ginseng extracts in BALB/c mice. Results: Our results showed that most prominently, RGE (in almost all experiments) exhibited excellent antioxidant effects via increasing superoxide dismutase, catalase, and glutathione peroxidase activities in the liver and decreasing serum 8-hydroxy-2'-deoxyguanosine, aspartate aminotransferase, and lactate dehydrogenase levels compared with the groups treated with FRGE and BRGE. Moreover, RGE significantly increased the number of white blood cells, especially T and B lymphocytes, and antibody-forming cells in the spleen and thymus, and it also activated a number of immune cell subtypes. Conclusion: Taken together, these results indicate that RGE is the best supplement for consumption in everyday life for overall health-enhancing properties.

The metabolic profiles of Panax quinquefolius and its associated therapeutic values are critically affected by the repetitious steaming times. The times-dependent steaming effect of P. quinquefolius is not well-characterized and there is also no official guideline on its times of steaming. In this paper, a UPLC-Q-TOF-MS/MS method was developed for the qualitative profiling of multi-parametric metabolic changes of raw P. quinquefolius during the repetitious steaming process. Our method was successful in discriminating the differentially multi-steamed herbs. Meantime, the repetitious steaming-inducing chemical transformations in the preparation of black American ginseng (American ginseng that was subjected to 9 cycles of steaming treatment) were evaluated by this UPLC-Q-TOF-MS/MS based chemical profiling method. Under the optimized UPLC-Q-TOF-MS/MS conditions, 29 major ginsenosides were unambiguously identified and/or tentatively assigned in both raw and multi-steamed P. quinquefolius within 19 min, among them 18 ginsenosides were detected to be newly generated during the preparatory process of black American ginseng. The mechanisms involved were further deduced to be hydrolysis, dehydration, decarboxylation and addition reactions of the original ginsenosides in raw P. quinquefolius through analyzing mimic 9 cycles of steaming extracts of 14 pure reference ginsenosides. Our novel steaming times-dependent metabolic profiling approach represents the paradigm shift in the global quality control of multi-steamed P. quinquefolius products.

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.

The purpose of this study is to prepare black Panax ginseng leaf (PGL) and evaluate its antioxidative effect. In order to make black PGL, the raw PGL was successiely steamed at $95^{\circ}C$ for 3 hr nine times. The antioxidant activities of total saponins (Sa) from PGL and black PGL against peroxyl radicals and peroxynitrites were determined by the total oxy-radical scavenging capacity (TOSC) assay. Specific TOSC values for black PGL-Sa against peroxyl radicals and peroxynitrites were 2.3-fold and 2.1-fold of PGL-Sa, respectively, and 2.2-fold and 5.2-fold of glutathione, a positive control antioxidant, respectively. The black PGL-Sa exhibited stronger antioxidative effect than PGL-Sa. The main ginsenosides of black PGL were $Rg_3,\;Rk_1\;and\;Rg_5$. Among the saponins in black PGL, the amount of ginsenoside $Rg_3$ was examined by HPLC. 22.12 mg of ginsenoside $Rg_3$ was obtained from 1g of dried black PGL.
