Objectives : This study aims to analyze the anti-obesity effect of Syzygium aromaticum L. (SA) in obese mice made by a 60% high-fat diet (HFD). Methods : The antioxidant activities of SA were evaluated in vitro. To assess the anti-obesity effect of SA, male C57BL/6 mice were divided into five groups: Normal, Control, GC100 (Garcinia cambogia 100 mg/kg/day), SA100 (SA 100 mg/kg/day), SA200 (SA 200 mg/kg/day). All groups underwent a 6-week regimen of HFD and oral administration, except for the Normal group. Subsequently, we performed blood analysis, western blotting, and histopathological staining. Results : SA demonstrated effectiveness in antioxidant measurements. SA treatment resulted in a significant decrease in body weight gain, along with reductions in liver and epididymal fat weights. Serum triglyceride (TG), total cholesterol (TC), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and leptin levels were reduced with SA treatment. Moreover, in the SA100 group, the reduction of both TG and TC synthesis was caused by inhibiting the sterol regulatory element-binding transcription factor 1 (SREBP-1) and sterol regulatory element-binding transcription factor 2 (SREBP-2) through the Sirtuin 1 (Sirt1)/phospho-AMP-activated protein kinase (p-AMPK) pathway. Furthermore, SA treatment at a dose of 100 mg/kg reduced the accumulation of lipid droplets in the liver and the adipocyte size of the epididymal fat. Conclusion : Our research reveals the anti-obesity effects of SA by demonstrating its ability to inhibit body weight gain and lipid accumulation, suggesting that SA might be promising for obesity treatment.

Arctii Fructus (AF), which contains arctigenin (ARC) as a major constituent, is traditionally used as an anti-inflammatory medicine to treat inflammatory sore throat. Although several studies have proven its anti-inflammatory effects, there have been no reports on its use in inflammation related disorders such as obesity, cancer metastasis, and allergic responses. This study investigated the anti-obesity effect and anti-metastasis effect of AF and ARC. AF and ARC inhibited weight gain by reducing the mass of white adipose tissue in high fat diet (HFD)-induced obese mice. Serum cholesterol levels were also improved by AF and ARC. In in vitro experiments, AF and ARC decreased differentiation of white adipocytes. Furthermore, AF induced differentiation of brown adipocytes, which are able to consume surplus energy through non-shivering thermogenesis. Also, AF and ARC inhibited colon cancer and lung metastasis of colon cancer. They suppressed not only colorectal cancer cell progression by inhibiting cell growth, but also prohibited lung metastasis by regulating epithelial-mesenchymal transition (EMT), migration, and the invasion. These effects were confirmed in an experimental metastasis mouse model. In addition, AF and ARC inhibited mast cell mediated allergic responses. Collectively, our study suggests that AF and ARC might show inhibitory effects on inflammation related diseases, including obesity, cancer, cancer metastasis, and allergic responses.

Objectives We performed the simultaneous analysis for three compounds in Cheongsimyeonja-tang (CSYJT) and evaluated its anti-obesity effect. Methods The column for separation of three compounds was used Gemini $C_{18}$ column and maintained at $40^{\circ}C$. The mobile phase for gradient elution consisted of two solvent systems. The analysis was carried out at a flow rate of 1.0 mL/min with PDA detection at 275 nm. The injection volume was $10{\mu}L$. 3T3-L1 preadipocytes were differentiated into adipocytes by adding insulin, dexamethasone and 3-isobutyl-1-methylxanthine (IBMX) for 8 days in the absence or presence of CSYJT. Anti-obesity effects of CSYJT were evaluated by Oil Red O staining, glycerol-3-phosphate dehydrogenase (GPDH) activity, triglyceride contents, and leptin production. Results Calibration curves were acquired with $r^2$ >0.9999. The contents of baicalin, wogonoside and baicalein in CSYJT were 14.54-14.65 mg/g, 5.24-5.27 mg/g and 0.01-0.02 mg/g, respectively. CSYJT showed inhibitory effect on lipid accumulation and GPDH activity in the differentiated 3T3-L1 cells. Furthermore, CSYJT significantly decreased contents of triglyceride and leptin production in 3T3-L1 adipocytes. Conclusions These results will be helpful to improve quality control and anti-obesity effect of Taeeumin CSYJT.

To investigate the effect of the frequently used anti-obese medicine GyeongshinhaeGihwan 1 (GGT1), in food intake, body weight and food efficiency ratio for high fat diet induced obese male rats. Also, to value the diffences between GyeogshinhaeGihwan 1 and FDA approved Sibutramine in anti-obesity effect. High fat diet induced obese male rats were classified into four groups - positive control group, negative control group, GyeongshinhaeGihwan 1 group and Sibutramine group - and their food intake and body weight were observed for eight weeks. Anti-obesity effect was estimated with food efficiency ratio which is calculated by weight inclose divided by food intake. The result shown in Fig. 2 suggests that the GyeongshinhaeGihwan 1 group is more effective on food intake control than the Sibutramine group. Average weight variation shows an increase in both positive/negative control group and medication group. Also, the result in Fig. 3 indicates that average food efficiency ratio decreases contrary to the average weight variation. In addition, repeatedly estimated variance analysis on average food efficiency ratio of the GyeonushinhaeGihwan 1 group shows (1) the result corollary to the time of observation of food efficiency ratio was effective under 0.05 variance (P-value 0.000). The differences between each groups were not shown under 0.05 variance. Compared to the control group, medication groups were visually more effective on food intake control. Although both groups had a tendency of weight increasing, food efficiency ratio considering food intake and weight variation rate showed a decrease. Especially, the medication group variated less than the control group corollary to the point of time, proving the individuals react less sensitive to the medicine. Moreover, there were no differences in the anti-obesity effect between GyeongshinhaeGihwan 1 group and Sibutramine group studied by repeatedly estimating variance analysis(P-value: 0.610). When considering Sibutramine as an anti-obesity medicine approved by FDA, the point of being classifed in the same group proves the effect of GyeongshinhaeGihwan 1 as an anti-obesity medicine.

Resveratrol (3,4,5-trihydroxy-trans-stilbene), a phytoalexin found in grape skin, grape products, and peanuts as well as red wine, has been reported to have various biological and pharmacological properties. The purpose of this study was to investigate the anti-obesity effect of resveratrol-amplified grape skin extracts on adipocytes. The anti-obesity effects of grape skin extracts were investigated by measuring proliferation and differentiation in 3T3-L1 cells. The effect of grape skin ethanol extracts on cell proliferation was detected by the MTS assay. The morphological changes and degree of adipogenesis of preadipocyte 3T3-L1 cells were measured by Oil Red-O staining assay. Treatment with extracts of resveratrol-amplified grape skin decreased lipid accumulation and glycerol-3-phosphate dehydrogenase activity without affecting 3T3-L1 cell viability. Grape skin extract treatment resulted in significantly attenuated expression of key adipogenic transcription factors, including peroxisome proliferator-activated receptor, CCAAT/enhancer-binding proteins, and their target genes (FAS, aP2, SCD-1, and LPL). These results indicate that resveratrol-amplified grape skin extracts may be useful for preventing obesity by regulating lipid metabolism.

Rhodosporidium toruloides, an oleaginous yeast, can be used as a fast and reliable evaluation tool to screen new natural lipid-lowering agents. Herein, we showed that triglyceride (TG) accumulation was inhibited by 42.6% in 0.1% red radish coral sprout extract (RRSE)-treated R. toruloides. We also evaluated the anti-obesity effect of the RRSE in a mouse model. The body weight gain of mice fed a high-fat diet (HFD) with 0.1% RRSE (HFD-RRSE) was significantly decreased by 60% compared with that mice fed the HFD alone after the 8-week experimental period. Body fat of the HFD-RRSE-fed group was dramatically reduced by 38.3% compared with that of the HFD-fed group.

Objectives : Adipogenesis was defined as a differentiation process of preadipocytes into the adipocytes. Thus, to control of this process can be one of the most important strategies to prevent obesity. Korean ginseng(Panax ginseng C.A. Meyer) is one of the most widely used medicinal herbs. Although multiple biological activities of Korean ginseng, particularly ginsenosides, have been known, the anti-adipogenic role and function of polysaccharides from Korean ginseng are still unclear. In this study, we examined anti-adipogenic activity of polysaccharides and its molecular basis mechanisms are further investigated.Methods : The cytotoxicity of KGP in 3T3-L1 was evaluated by MTT assay. Anti-adipogenic effect of KGP was examined by Oil Red O (ORO) staining and microscopy observation in 3T3-L1 mature adipocytes. The mRNA expression levels of adipogenic transcriptional factors were analyzed by reverse transcription-polymer chain reaction (RT-PCR). To elucidate the adipogenic molecular mechanism of KGT, SB431542 (TGF-β specific inhibitor) was used.Results : We found that polysaccharides showed no effect on the viability of 3T3-L1 preadipocytes. Dose dependent inhibitory effect of polysaccharides on 3T3-L1 adipogenesis was observed as judged by ORO staining and microscopic image analysis. To obtain further mechanistic insight into anti-adipogenic function of polysaccharides, we then tested the effect of polysaccharides treatment on the adipogenic marker genes. The mRNA expressions level of C/EBPα, PPARγ, C/EBPβ, and fatty acid synthase (FAS) were dose-dependently inhibited by KGP treatment in 3T3-L1 mature adipocytes.Conclusions : In conclusion, these findings suggest that the KGP could be used in treatment of obesity and overweight related diseases.
