  • The antiobesity effect of the mixture of black garlic and Garsinia cambogia extracts (BGG) was investigated by measuring the Oil red O staining and the expressions of adipogenic genes during preadipocyte differentiation by real-time PCR in the 3T3-L1 adipocytes. BGG reduced contents of Oil red O dye in the 3T3-L1 adipocytes. mRNA expression levels of SREBP1c, C/EBPa, aP2/FABP4, and $PPAR{\gamma}$ which are adipogenic transcription factor, in cells treated with BGG were also significantly down regulated. Also, the phosphorylation of AMP-activated protein kinase (AMPK) in L6 cells was more increased by BGG. These results indicate that BGG seems to be more attractive compound for application of industry than individual extracts such as black garlic and Garsinia cambogia, considering it has two effects not only inhibit the preadipocyte differentiation but also activate the phosphorylation of AMPK unlike other two compound.

  • Resveratrol (3,5,4'-trihydroxy-trans-stilbene) has been considered to be as one of major antioxidants present in grapes responsible for beneficial effects of red wine consumption on coronary heart disease. This triphenolic stilbene has been suggested as a potential cancer chemopreventive agent based on its striking inhiitory effects on diverse cellular events associated with tumor initiation, promotion, and progression. The compound has strong antioxidative and anti-inflammatory activities which amy contribute to its chemopreventive/chemoprotective properties. In the present work, we have found that resveratrol reduces viability and DNA synthesis capability of cultured human promyelocytic leukemia (HL-60) cells. Likewise, the viability of human breast cancer cell line, MCF-7 was reduced by resveratrol treatment. The growth inhibitory and antiproliferative properties of resveratrol appear to be associated with its induction of apoptotic cell death as determined by morphological and ultrastructural changes, agarose gel electrphoretic analysis of internucleosomal DNA fragmentation, and in situ terminal end-labeling of fragmented DNA (TUNEL). This compound also inhibited the phorbol ester-induced expression of cyclooxygenase-2 (COX-2) protein in immortalized human mammary epithelial MCF-10A cells. These results suggest that resveratrol has the promising cancer therapeutic/chemopreventive potential.

  • In this study, we identified that the fermentation of Korean indigenous probiotics and red ginseng produced ginsenoside compound K (CK) from major ginsenosides. Based on whole genome sequencing of 19 probiotics species, β-glucosidase, α-arabinofuranosidase, β-xylosidase, and α-rhamnosidase related to bioconversion of ginsenosides are identified in the genome of 19 species, 3 species, 6 species, and 8 species, respectively. Among the 19 probiotics species, Bifidobacterium longum CBT BG7 converted from ginsenoside Rb1 to CK, and both B. breve CBT BR3 and B. lactis CBT BL3 converted ginsenoside Rb1 to Rd. The final concentration and yield of ginsenoside F2 and CK were higher in the fermentation with the nondisrupted cells than with disrupted cells. The combination of both CBT BG7 and BL3, and CBT BG7 and BR3 showed higher amounts of F2 than CBT BG7 only. CBT BG7 with adding α-amylase increased the amounts of F2. In this study, we identified that the fermentation of both Korean indigenous probiotic bacteria CBT BG7, BR3 and BL3, and red gingseng is able to produce CK, a bioactive compound that promotes health benefits.

  • This clinical study was performed to evaluate whether supplementation of proton pump inhibitor (PPI)-based triple therapy with Korean red ginseng can enhance Helicobacter pylori (H. pylori) eradication and reduce levels of halitosis-associated volatile sulfur compounds (VSCs) in the stomach. Seventy-six patients were randomized into an eradication regimen-only group (n=45) or an eradication regimen plus 10 weeks of Korean red ginseng supplementation group (n=31). The eradication regimen consisted of PPI b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.. for seven days. Korean red ginseng supplementation commenced on the last day of the eradication regimen. $^{13}C$-urea breath test and halimeter measurements were performed prior to protocol repetition. By intention-to-treat analysis, the H. pylori eradication rate in the Korean red ginseng group (77.4%, 24 of 31) was higher than that in the control group (45.0%, 26 of 45). However, by per protocol analysis, the eradication rate in the Korean red ginseng group was significantly higher than that in the control group (92.3%, 24/26 vs. 69.4%, 26/38; p<0.05). H. pylori infection was significantly associated with increased VSC levels. However, VSC levels decreased significantly in the Korean red ginseng group (p<0.05). In conclusion, supplementation of triple therapy with Korean red ginseng increased the H. pylori eradication rate and led to significant reductions in VSC levels, suggesting the usefulness of this substance in combating H. pylori infection.

  • Mahwang-Shin-Gung-San has been found inhibiting the mast cell-mediated anaphylactic reaction. This report describes an inhibitory effect of Mahwang-Shin-Gung-San (MSGS) on the immediate-type cutaneous allergic reactions. MSGS has concentration -dependently inhibited the ear swelling response induced by compound 48/80 in mouse by intradermal injection. The mast cells in mouse ear tissue undergone ear-swelling response by compound 48/80 were stained by alcian blue/nuclear fast red. MSGS significantly inhibited the compound 48/80-induced degranulation from mast cells in ear tissue. MSGS concentration-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80. We also studied the effect of MSGS on mast cell-dependent passive cutaneous anaphylaxis (PCA) activated by dinitrophenyl IgE antibody. MSGS showed potent inhibition of PCA by oral administration. These results indicate that MSGS inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

  • In this study red ginseng was extracted with ethanol and then fermented by yeasts including Lactobacillus casei and Bifidobacterium longum. Fermented red ginseng extracts(FRGE) were found to be more effective antioxidants in vitro with regards to 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activity than red ginseng extracts(RGE). In FRGE, the contents of ginsenosides $Rb_1$, $-Rb_2$ and -Rc were much lower than in RGE, however, the contents of ginsenosides 20(S)$-Rg_3$, 20(R)$-Rg_3$ and compound K were higher than RGE. FRGE was added to Yanggaeng(0, 5, 10, 15, 20%), and physicochemical and sensory evaluations of the Yanggaeng were conducted. The L and b values of Yanggaeng with added FRGE were decreased by increasing the ratio of FRGE, while the a value was increased. Sensory evaluations for, taste, color, flavor, texture and overall acceptability of Yanggaeng with addition of FRGE (10%) were applicable for improving the Yanggaeng product.

  • Red ginseng marc (RGM) has been used on primary industries using fertilizer or forage, and it mostly has been dumped. To improve utilization of RGM, the biological activities of RGM were examined. RGM was extracted and fractionated using various solvents and their biological activities were compared. The hexane fraction from the methanol extract of RGM (RGMMH) showed strong anti-cancer activity (58.56 ± 6.04% at 100 ㎍/mL) and anti-inflammatory effect (65.72 ± 1.33% at 100 ㎍/mL). But, oil extract of RGM extracted with hexane (RGMH) showed low activities (anti-cancer: 16.42 ± 3.33%, at 100 ㎍/mL, anti-inflammatory activity: 29.46 ± 2.10%, at 100 ㎍/mL). Their metabolites were analyzed using HPLC. Panaxydol known as anti-cancer compound of RGM was one of major compounds in RGMMH. Meanwhile, panaxydol was detected in trace amount in red ginseng marc oil (RGMH). In addition, RGMMH and RGMH showed big differences in HPLC profiling. This research suggests optimal extraction method of RGM oil.
