  • In this study, we designed to confirm the dietary effect of anti-obesity of fermented soybean curd residue (FSCR; SCR-Meju; Biji-meju) by A. oryzae, which is well known as a Korean traditional meju microbe. We observed that body weight gain, serum and hepatic lipid profile, as well as the activity of ROS generating enzyme and ROS scavenging enzyme in high-fat diet induced obese mice fed experimental diet (SCR and SCR-meju). Body weight gain and epididymal fat weight of HC (high-fat diet control) was markedly higher than that of NC (Normal control). Conversely, body weight gain and epididymal fat weight of the SCR (Biji) and SCR-meju (Biji-meju) group was significantly lower than that of HC; these of the SCR-meju group was lower than that of the SCR group. Furthermore, serum TG and total-cholesterol and LDL-cholesterol contents of SCR and SCR-meju groups were lower than that of HC, and HDL-cholesterol level of the SCR-meju group was significantly higher than that of HC. In conclusion, although precise mechanisms of the antiobese effects of SCR-meju in this study are unknown, the present study provides an experimental evidence that SCR-meju may prevent obesity and obesity related metabolic syndromes, such as hyperlipidemia, hypertension and diabetes, and liver disease by high-fat diet. Nevertheless, further study in this filed will be needed.

  • This study was to investigate whether cultivated ginseng (CG), cultivated wild simulated ginseng (CWG) and cultivated red ginseng (CRG) extracts influences on the obesity. The saponin contents of 3 kinds of ginsengs were analysed by HPLC-ESI-TOF-MS. Total saponin contents were determined in CG on the most contents and since red ginseng has the highest PD (protopanaxadiol type) / PT (protopanaxatriol type) ratio, there may be differences between ginseng, wild ginseng, and red ginseng with respect to their pharmacological effects. Male C57BL/6J mice were fed a normal diet(N), HFD (60% Kcal fat, C), HFD with CG, CWG and CRG extracts (800 mg/kg) for 5 weeks. We observed change of total body weight, degree of hepatic lipid accumulation and immunohistochemical change of GLP-1 and insulin-secreting cells. Also this study attempts to use the physiological analysis method to analyze the changes of blood lipids, insulin and leptin concentration. The change of body weight and size of accumulated lipid droplets in liver lobules decreased in all of the experimental groups than the control(C) group. In the pancreas, the immunohistochemical density of insulin-secreting cells were significantly stronger in the CWG and CRG than C group. The levels of serum insulin and leptin significantly decreased 55.6%, 54.3% respectively in CWG and CRG. The changes of triglyceride, total cholesterol in serum decreased in CRG than the C group. Obesity related CG, CWG and CRG extracts might have contribute to improvement of obesity by regulating the levels of blood lipids and biochemical indicator of fat accumulation.

  • Agaricus blazei Murill (Almond mushroom) has many beneficial effects, such as anti-cancer, immuneenhancement, and anti-obesity. Also, its skin benefits have been reported for antioxidant, anti-inflammatory, and whitening. In order to elucidate these effects, many studies have been conducted. In this study, we reconfirmed the skin efficacy of the extract of the mushrooms mushrooms. The Agaricus blazei extract showed inhibition of melanin synthesis, enhancement of collagen synthesis, and up-regulation of gene expression (hyaluronan syntahase-2, 3 and aquaporin-3) at 100 ㎍/mL. and identified the ingredients from the extract. We further investigated them to find an applicability as cosmetic ingredients. The ingredients were confirmed comparison of their spectroscopic data with literature values. They were identified as being ergosterol (1), 5-dihydroergosterol (2), cerevisterol (3), cerebroside B (4), cerebroside D (5), adenosine (6), and benzoic acid (7). Among these compounds, we evaluated skin efficacy for two cerebrosides and three ergosterol derivatives that have not been reported its efficacy. As a result, 5-dihydroergosterol (2) inhibited melanogenesis in B16F10 and promoted collagen biosynthesis in human dermal fibroblast. In addition, cerevisterol (3), cerebroside B (4), and cerebroside D (5) inhibited NO production in RAW 264.7 cell. In particular, cerebroside D (5) increased the expression of hyaluronan synthase-2 and aquaporin-3 genes in HaCaT. These results suggest that Agaricus blazei extract and isolated compounds can be used as cosmetic ingredients.

  • The aim of the study was to investigate the anti-obesity effect of Coprinus comatus (CC) in high-fat diet-fed Zucker rat (fa/fa). Obesity was induced by feeding on high-fat diet (HFD) containing 60% kcal fat for 10 weeks, in which CC extracts were administrated through the gastrointestinal tract at a concentration of 200 mg/kg BW/day for 10 weeks. The total polyphenol and flavonoid contents of CC extracts were found to be $18.5{\pm}1.1mg$ of catechin equivalent/g, and $5.24{\pm}0.54mg$ of quercetin equivalent/g extract, respectively. The DPPH, ABTS, and hydroxyl radical scavenging activities of CC extracts were 15.34 %, 17.25%, and 16.18%, respectively. In animal study, CC administration significantly reduced the body weight, while there were no significant differences in the daily food intake between the HFD-fed Zucker rats and HFD plus CC-fed rats. CC treatment decreased epididymal and perirenal fat weights in HFD-fed Zucker rats. Significant decreases in the levels of triglyceride and total cholesterol in the serum and liver were observed in the CC-treated group compared with HFD-fed Zucker rats. Serum HDL-cholesterol levels in the CC-treated group were increased compared with the HFD-fed groups. Serum AST and ALT activities in the CC group were significantly lower than those of the HFD-fed group. Taken together, these data demonstrated that CC has potential in preventing high-fat diet induced obesity and is a good candidate for an anti-obesity agent.

  • This study investigate the effects of extracts of five species of Korean native forest plants on lipid accumulation and reactive oxygen species (ROS) production during the differentiation of 3T3-L1 cells. Our results show that Korean native forest plants extracts significantly reduced lipid accumulation and ROS production during adipogenesis in 3T3-L1 cells. Especially, Rubus coreanus Miq. was most effective in the inhibition of lipid accumulation and ROS production at a concentration of $100{\mu}g/mL$. Moreover, Rubus coreanus Miq. extracts significantly inhibited adipocyte differentiation, which is dependent on down-regulation of peroxisome proliferator-activated receptor gamma, CCAAT/enhancer-binding protein alpha, and adipocyte-specific fatty acid binding protein, a key adipogenic transcription factor. Therefore, these results suggest that Rubus coreanus Miq. might be a valuable source of bioactive compounds with anti-adipogenic activity.

  • Codonopsis lanceolata (Deoduk) was grown in East Asia, including Korea, China, Japan, and Russia, and the roots of C. lanceolata have been used as functional foods and traditional medicine to treat symptoms of cough, bronchitis, asthma, tuberculosis, and dyspepsia. The phytochemicals of C. lanceolata have been reported such as phenylpropanoids, polyacetylenes, saponins, and flavonoids that are involved in pharmacological effects such as anti-obesity, anti-inflammation, anti-tumor, anti-oxidant, and anti-microbial activities. Selecting marker substances of the main producing area by MS-based metabolomics analysis is important to ensure the beneficial effect of C. lanceolata without side-effects because differences in cultivated areas of plants were related not only to the safety of medicinal plants but also to changes in chemical composition and biological efficacy. In our present study, ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry combined with multivariate statistical analysis was applied to recognize the main producing area of C. lanceolata in South Korea. As a result of Principal Component Analysis and loading plot analysis of three groups, Inje (Kangwon-do), Hoengseong (Kangwon-do), and Muju (Jeonlabuk-do), several secondary metabolites of C. lanceolata including tangshenoside I, lancemaside A, and lancemaside G, were suggested as potential marker substances to distinguish the place of main producing area of C. lanceolata.

  • Polymethoxyflavones (PMFs) are flavonoids mainly found in citrus fruits and have been reported to exhibit a wide range of bioactivities, including anti-obesity, anti-cancer, and anti-inflammatory actions. To utilize PMFs as functional materials, it is necessary to develop a simple method of obtaining PMFs from citrus tissues containing a large amount of PMFs. It has been reported that Jinkyool (C. sunki Hort ex. Tanaka) peel contained a large amount of PMFs, but there are no studies on PMFs isolated from its leaves. In this study, we established a simple procedure for obtaining the PMF-rich fraction (PRF) from the leaves of Jinkyool and investigated the effects of PRF on lipid metabolism in 3T3-L1 cells. PRF inhibited lipogenesis during the differentiation of 3T3-L1 preadipocytes. It decreased the expression of peroxisome proliferator-activated receptor gamma (PPAR𝛾) and CCAAT/enhancer binding protein alpha (CEBP𝛼), FAS, and adipocyte fatty-acid-binding protein 2 (aP2). In mature 3T3-L1 adipocytes, PRF increases the phosphorylation of protein kinase A (PKA)/hormone-sensitive lipase (HSL), which are key factors involved in lipolysis. Moreover, it increases the phosphorylation of the AMP-activated protein kinase (AMPK)/acetyl-CoA carboxylase (ACC) involved in fatty acid oxidation. These results suggest that PRF from Jinkyool leaves can be used as an anti-obesity agent with the action of inhibiting lipogenesis and promoting lipolysis and fatty acid oxidation in 3T3-L1 adipocytes.

  • Objectives : The purpose of this study was to determine the anti-obesity effect and molecular mechanism of YY312, a herbal extract composed of Imperatae Rhizoma, Citri Unshius Pericarpium Immaturus, and Evodiae Fructus, on a high-fat diet-induced animal model and on 3T3-L1 cells. Methods : C57BL/6 mice were fed for 6 weeks with a normal diet or a high-fat diet (HFD). Then they orally administered daily with 300 mg/kg YY312 for next 10 weeks. Body weight and food consumption were recorded weekly and daily, respectively. Tissue weights, serum lipid, and glucose levels were analyzed at the end of the study. Additionally, the effects of YY312 on adipocyte differentiation in 3T3-L1 cells were examined. After differentiating 3T3-L1 cells were treated with YY312, Oil-red O staining, RT-PCR, and Western blotting were performed for lipid accumulation, mRNA expression of adipogenesis gene, and AMP-activated protein kinase (AMPK) phosphorylation, respectively. Results : YY312-administered mice showed a significant reduction of body weights and abdominal adipose tissue weights. YY312 also reduced the serum levels of triglycerides and total cholesterol, compared with the HFD group. Treatment with YY312 inhibited lipid accumulation and blocked expression of adipogenic transcription factors and lipogenesis genes, including peroxisome proliferator-activated receptor ${\gamma}$, CCAT/enhancer binding protein ${\alpha}$ and fatty acid synthase. YY312 increased AMPK phosphorylation in 3T3-L1 adipocytes. Conclusions : This study showed that herbal extract YY312 has an anti-obesity effect in vitro and in vivo. Thus, YY312 could be developed as a supplement for reduction of body weight gain induced by an HFD.

  • Objectives : AMP-activated protein kinase (AMPK) is a key metabolic regulator that reduces lipogenesis. AMPK is mainly activated via phosphorylation of liver kinase B (LKB) 1 under energy stress. Here, we highlighted the anti-obesity effect and underlying mechanism of Coix lacryma-jobi var. mayuen Stapf sprout water extract (CSW) sprout extract in connection with the LKB1/AMPK signaling pathway. Methods : C57BL/6 mice (20~25 g) fed HFD to induce obesity and at the same time administered CSW 100 mg/kg (CSWL; (CSWL; CSW low concentration) or CSW 200 mg/kg (CSWH; CSW high concentration) or Garcinia extract (Garcinia) 200 mg/kg orally for 6 weeks. Body weight and food intake were measured at the same time each day. After 6 weeks of CSW administration, liver tissue and serum were obtained through an autopsy. After the end of the experiment, biochemical analysis (triglycerides (TG), total cholesterol (TC), HDL-cholesterol, and LDL-cholesterol) was performed on the serum. And then, protein levels related to TG and TC synthesis were measured through western blot analysis in liver tissue. Results : As a result, serum TG, TC, and LDL-cholesterol levels were significantly increased in the control group and significantly decreased in the CSW administration group. On the other hand, the HDL-cholesterol level was increased in the CSW-administered group. And as a result of Western blot analysis, CSW significantly increased the phosphorylation of LKB1 & AMPK, and remarkably decreased the expression of factors related to TG and TC synthesis. Conclusions : Our findings suggest that CSW influences the TG and TC synthesis to positively affect HFD-induced obesity in C57BL/6 mice.

  • A controlled and double blinded trial was performed to evaluate the effects of OPE supplementation on blood circulation in healthy male smokers. The study population consisted of 92 healthy male smokers aged $44.4{\pm}7.8$ years. The supplement group (n=49) received OPE containing 100 mg quercetin/day for 10 weeks, while the control group (n=43) received placebo powders. The prothrombin time and activated partial thromboplastin time increased significantly after OPE consumption, indicating the attenuated blood clot formation by OPE. In conclusion, these results indicate that the daily consumption of OPE (containing 100 mg quercetin) for 10 weeks exerts significant health benefits through the modulation of physiological functions including the blood circulation in male smokers.
