  • Ginseng is a popular medicinal plant highly valued throughout the world. Asian ginseng is one of the most common species of ginseng. It has long occupied a significant position in oriental medicine and has been justified its name as the 'king herb'. As a nutritional supplement, ginseng is an extremely common and popular herbal medicine in the United States and Canada in recent decades. The multiple constituents of ginseng possess equally multifaceted pharmacological actions as demonstrated by numerous studies. Ginseng root and its constituents influenced the central nervous system, endocrine, cardiovascular, gastrointestinal system, sexual, renal organ and immune system, etc. One important action is its anti-hyperglycemic effect. Previous studies on ginseng demonstrate that only the root of ginseng has been used in the treatment of diabetes, while the other parts of ginseng plant were always neglected. Recently, we analyzed the constituents of ginseng berry, leaf and discovered that ginseng berry, leaf extracts and its total ginsenosides have the ability to reduce hyperglycemia and body weight and increase the peripheral glucose utilization in obese or diabetic ob/ob or db/db mice. Our data suggest that all parts of ginseng plant, including root, berry, leaf and stem exhibit potent anti-hyperglycemic and anti-obese effects and may provide an opportunity to develop a novel class of anti-diabetic agents.

  • Background: The Panax ginseng berry extract (GBE) is well known to have an antidiabetic effect. The aim of this study is to evaluate and investigate the protective effect of ultrasonication-processed P. ginseng berry extract (UGBE) compared with GBE on liver fibrosis induced by mild bile duct ligation (MBDL) model in rats. After ultrasonication process, the composition ratio of ginsenoside in GBE was changed. The component ratio of ginsenosides Rh1, Rh4, Rg2, Rg3, Rk1, Rk3, and F4 in the extract was elevated. Methods: In this study, the protective effect of the newly developed UGBE was evaluated on hepatotoxicity and neuronal damage in MBDL model. Silymarin (150 mg/kg) was used for positive control. UGBE (100 mg/kg, 250 mg/kg, 500 mg/kg), GBE (250 mg/kg), and silymarin (150 mg/kg) were orally administered for 6 weeks after MBDL surgery. Results: The MBDL surgery induced severe hepatotoxicity that leads to liver inflammation in rats. Also, the serum ammonia level was increased by MBDL surgery. However, the liver dysfunction of MBDL surgery-operated rats was attenuated by UGBE treatment via myeloid differentiation factor 88-dependent Toll-like receptor 4 signaling pathways. Conclusion: UGBE has a protective effect on liver fibrosis induced by MBDL in rats through inhibition of the TLR4 signaling pathway in liver.

  • Background: Acute hepatic failure is a life-threatening critical condition associated with rapid deterioration of liver function and liver transplantation. Several studies have shown that Panax ginseng Mayer has antidiabetic and hepatoprotective effects. However, the hepatoprotective effect of ginseng berry is still unveiled. In this study, we evaluated the hepatoprotective effects of ultrasonication-processed ginseng berry extract (UGBE) on acute hepatic failure model in rats. Methods: Ginseng berry extract (GBE) was ultrasonically processed. The GBE, silymarin, and UGBE were orally administered to male Sprague-Dawley rats for 4 wk. Twenty-four h after the last administration, rats were challenged with D-galactosamine (D-GalN)/lipopolysaccharide (LPS). Results: After ultrasonication, the component ratio of ginsenosides Rg2, Rg3, Rh1, Rh4, Rk1, Rk3, and F4 in GBE had been elevated. Administration of UGBE significantly increased the survival rate of D-GalN/LPS-challenged rats. Pretreatment with UGBE significantly decreased serum alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels in D-GalN/LPS-challenged rats in a dose-dependent manner. The levels of enzymatic markers for oxidative stress (superoxide dismutase, glutathione peroxidase, catalase, and glutathione) were increased by UGBE treatment in a dose-dependent manner. Tumor necrosis factor alphalevel, inducible nitric oxide synthase activities, and nitric oxide productions were reduced by UGBE treatment. In addition, hemeoxygenase-1 levels in liver were also significantly increased in the UGBE-treated group. The protein expression of toll-like receptor 4 was decreased by UGBE administration. Hematoxylin and eosin staining results also supported the results of this study showing normal appearance of liver histopathology in the UGBE-treated group. Conclusion: UGBE showed a great hepatoprotective effect on D-GalN/LPS-challenged rats via the toll-like receptor 4 signaling pathway.

  • Ginsenosides in ginseng berry has been known as functional materials showing physiological effect to the human. Specially, ginseng berry contains plenty of ginsenoside Re, but the study of extraction processes were not enough performed. Accordingly, the purpose of this study was to establish the optimized extraction process for obtaining ginsenoside Re from ginseng berry. The extraction process of ginsenosides was performed in 250 mL extraction flask containing 150 solvent and 10 g of dried ginseng berry. The extracted ginsenoside Re, Rg1 and Rd and total crude ginsenosides from ginseng berry were evaluated by TLC according to the treated conditions (the ratio of alcohol to water, extraction temperature, extraction period, and extraction times). Optimized conditions for extraction was 70% to 30% of the ratio of alcohol to water, $80^{\circ}C$ of extraction temperature, 4 h of extraction period, and 2 times of extraction frequency. The amount of total crude ginsenosides of the extract obtained from the optimized process was 88.6 mg/g based on dried ginseng berry. The composition of ginsenosides from the extracted was 5.5% of Rb1, 5.2% of Rc, 14.3% of Rd, 51.5% of Re, 8.1% of Rf, and 15.7% of Rg1. A protopanaxtriol ginsenosides of whole ginsenosides extracted was about 80%.

  • The abolishment of the red ginseng monopoly act by the Korean government in 1996 resulted in a drastic change in the Korean ginseng industry, leading to a significant increase in the market size and consumption of ginseng products. Red ginseng is most popular type, with approximately 74% of harvested fresh ginseng being processed into various red ginseng products. Since 1997, there has been a substantial increase in the cultivation of ginseng for production of red ginseng, which, in turn, has contributed to the proliferation of ginseng processing companies. To investigate the products of ginseng manufacturing businesses, we select 200 companies primarily engaged in ginseng processing or specializing solely in ginseng. Our survey on the status of ginseng industry covered 8 different categories. 1) Root ginseng: There were 66 companies involved in manufacturing red ginseng root, accounting for 33.0% of all surveyed companies. This was followed by black ginseng root with 36 companies (18.0%) and red ginseng fine roots with 22 companies (11%). 2) Red ginseng products: A total of 144 companies were involved in manufacturing red ginseng pouches, making it the most common product category. This was closely followed by 142 companies producing pure(100%) red ginseng extract concentrate. 3) Fermented red ginseng products: Companies producing fermented red ginseng extract concentrate products were the most numerous, totaling 26. Following this, companies producing fermented red ginseng stick and pouch products were next in line. 4) Ginseng products: There were 15 companies involved in the production of ginseng products, with the majority focusing on ginseng tea. 5) Black ginseng products: Companies producing black ginseng extract concentrate were the most numerous, with 31 companies, followed by 26 companies producing black ginseng extract pouches. 6) Taegeuk ginseng products: Only 5 companies were involved in the production of taegeuk ginseng products. 7) Fermented black ginseng, and 8) Ginseng berry products: These categories are manufactured by less than 5 companies each. However, the variety in ginseng berry products suggests the potential for future growth. In the 2000s, a trend emerged with the development of new processed products aimed at enhancing the functional components of red ginseng, and these products have captured the attention of consumers. However, this study primarily focuses on black ginseng, fermented red ginseng/fermented black ginseng, and ginseng berry products as they have exerted a significant influence on the overall ginseng industry.

  • Background: Ginseng is a commonly used herbal medicine in treating various medical conditions. Chronic gut inflammation is a recognized factor for the development of colorectal cancer (CRC). In this project, Asian ginseng berry polysaccharide preparations were used to assess their effects on CRC and related immune regulation mechanisms. Methods: Ginseng berry polysaccharide extract (GBPE) and purified ginseng berry polysaccharide portion (GBPP) were used to evaluate their activities on human HCT-116 and HT-29 CRC cell proliferation. Interleukin-8 secretion analysis was performed on HT-29 cells. Naive CD4 cell isolation and T-helper cell differentiation were performed and determined using flow cytometry for Th1 and Treg in addition to cell cycle and apoptotic investigation. Results: GBPE and GBPP significantly inhibited interleukin-8 secretion and cancer cell proliferation, inhibited CD4+IFN-γ+ cell (Th1) differentiation, and decreased CD4+FoxP3+ cell (Treg) differentiation. Compared to the GBPE, GBPP showed more potent antiinflammatory activities on the malignant cells. This is consistent with the observation that GBPP can also inhibit Th1-cell differentiation better, suggesting that it has an important role in antiinflammation, whereas Treg cells hinder the body's immune response against malignancies. Supported by cell cycle and apoptosis data, GBPE and GBPP, at various degrees, remarkably enhanced the anticancer activities of 5-fluorouracil. Conclusion: Data from this project suggested that Asian ginseng berry potentially has clinical utility in managing enteric inflammation and suppressing CRC through immunomodulation mechanisms.
