Abstract
BACKGROUND Obesity, a global chronic disease, has been recognized as a severe risk to health. In our study, a novel polysaccharide named ARS was isolated and purified from aerial part of salviae miltiorrhizae radix. Our aim is to investigate the weight-reducing effect of a polysaccharide from salviae miltiorrhizae radix on mice fed a high-fat diet. RESULTS The novel polysaccharide ARS mainly consisted of glucose and galactose with a molar ratio of 0.59:1.00. We found that treatment with ARS could inhibit weight gain of mice fed a high-fat diet via modulating the intestinal bacteria. Moreover, we surveyed its mechanism in mice, and the gut microbiota sequencing results demonstrated that ARS can reverse or resist high-fat-diet-induced significant weight gain or obesity by increasing the diversity of gut microbiota and optimizing the ratio of Firmicutes to Bacteroidetes. Phylum and species analysis of gut microbiota demonstrated that obesity caused by a high-fat diet was accompanied by significant changes in the microbial communities, but ARS could reverse the disturbance of gut microbiota induced by the high-fat diet to maintain homeostasis. CONCLUSION Overall, our findings suggested a new function of ARS in regulating gut microbiota, which provides a theoretical basis for the development of high-quality ARS functional foods and the application of dietary supplements. © 2023 Society of Chemical Industry.

Abstract
Objective Various disease complications are a risk of overweight or obesity, so losing weight can reduce the risk of diseases caused by obesity. Binahong leaf ethanol extract (Anredera cordifolia) is a weight-loss herbal preparation. Aim This study aims to analyze whether A. cordifolia extract is effective in losing weight by affecting the mechanism of adipogenesis in an animal obesity model. Materials and Methods Animals were grouped into six groups as follows: the normal diet (K1), the negative control group (K2), the positive control group with Orlistat at a dose of 20 mg/kg BW (K3), an ethanol extract of A. cordifolia leaves at doses of 50 mg/kg BW (P1), 100 mg/kg BW group (P2), and 150 mg/kg BW (P3). All rats were fed a diet that consisted of high fat for eight weeks, except K1. Afterward, the treatments were given based on group distribution. Then, the rats were treated based on their groups for 4 weeks, and the high-fat diet was still given during the treatment for the control groups (K2). Anthropometric examinations such as body weight, length, and the circumference of the abdomen were measured. Metabolic parameters, including blood glucose, cholesterol levels, triglyceride levels, and abdominal fat weight, were measured using molecular parameters that measured PI3K levels and Extracellular signal-regulated kinase (ERK) in abdominal fat tissue samples using the ELISA method. Results ERK levels of abdominal fat were lowered in the treatment group using the extract of A. cordifolia (50 mg/kg BW (P1) and 100 mg/kg BW (P2)) compared to the control group that was given a high-fat diet without treatment. The control group, which was fed a high-fat diet without treatment, had an average ERK level of 10.17 ± 2.98 ng/ml, P1 (50 mg/kg BW). Furthermore, when ethanol extracts were used as opposed to the control group, which received a high-fat diet without treatment, there was an increase in phosphoinositide three-kinase (PI3K) levels (K2). The control group received 9.35 ± 2.87 ng/ml, the treatment group received 100 mg/kg BW (P2) 9.48 ± 1.54 ng/ml, and the treatment group received 150 mg/kg BW (P3) 7.87 ± 1.79 ng/ml. The weight of fat in the abdomen differed between the groups that received a high-fat diet without treatment (K2) and those that received a high-fat diet with treatment (P1, P2, P3; p < 0.05). Conclusion Anredera cordifolia extract possesses anti-obesity activities by decreasing ERK and increasing PI3K levels, as well as reducing abdominal fat weight.

Abstract
Erhuang Quzhi Granules (EQG), the Chinese herbal compound, has demonstrated significant clinical efficacy in treating non-alcoholic fatty liver disease (NAFLD). The mechanism of this treatment has been shown to involve the nuclear factor kappa B (NF-κB)/nod-like receptor thermal protein domain associated protein 3 (NLRP3) pathway. However, research on the material basis of EQG against NAFLD is still in its primary stages. Following these considerations, this study predicted and screened the active ingredients of EQG using the absorption, distribution, metabolism, and excretion (ADME) property evaluation tool and molecular docking. Then the levels of these active ingredients in EQG were measured using ultra-high-performance liquid chromatography (UHPLC). The efficacy of the active ingredients and their mechanisms were validated through both in vivo and in vitro experiments. The results indicate that the collected 12 components have favorable metabolic stability, are safe, and have drug-like properties. Aloe-emodin (AE), rhein (RH), curcumin (CUR), emodin (EM), and chrysophanol (CP) showed better binding affinity with TNF-α and Caspase-1 proteins. UHPLC analysis revealed that EQG contains AE, RH, CUR, EM, and CP. Cellular experiments proved that all these five ingredients reduce the accumulation of lipids and reactive oxygen species. In animal models of NAFLD, AE, and RH significantly improved the pathological symptoms of steatosis and fibrosis and reduced the levels of pro-inflammatory factors via the NF-κB/NLRP3 pathway. The results reveal the active ingredients of EQG for treating NAFLD based on the NF-κB/NLRP3 pathway and lay the foundation for the clinical promotion of EQG.

Abstract
Ginseng is a traditional medicine with health benefits for humans. Protopanaxadiol (PPD) is an important bioactive compound found in ginseng. Transgenic rice containing PPD has been generated previously. In the present study, extracts of this transgenic rice were evaluated to assess their antiadipogenic and anti-inflammatory activities. During adipogenesis, cells were treated with transgenic rice seed extracts. The results revealed that the concentrations of the rice seed extracts tested in this study did not affect cell viability at 3 days post-treatment. However, the rice seed extracts significantly reduced the accumulation of lipids in cells and suppressed the activation of CCAAT/enhancer-binding protein α (C/EBPα) and peroxisome proliferator-activated receptor γ (PPARγ), which in turn inhibited the expression of adipogenesis-related mRNAs, such as adiponectin, PPARγ, C/EBPα, sterol regulatory element-binding protein 1, glucose transport member 4, and fatty acid synthase. In adipocytes, the extracts significantly reduced the mRNA expression of inflammation-related factors following LPS treatment. The activation of NF-κB p65 and ERK 1/2 was inhibited in extract-treated adipocytes. Moreover, treatment with extract #8 markedly reduced the cell population of the G2/M phase. Collectively, these results indicate that transgenic rice containing PPD may act as an obesity-reducing and/or -preventing agent.

Tanshinone I specifically suppresses NLRP3 inflammasome activation by disrupting the association of NLRP3 and ASC. Mol Med 2023; 29:84. [PMID: 37400760 DOI: 10.1186/s10020-023-00671-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Abnormal activation of NLRP3 inflammasome is related to a series of inflammatory diseases, including type 2 diabetes, gouty arthritis, non-alcoholic steatohepatitis (NASH), and neurodegenerative disorders. Therefore, targeting NLRP3 inflammasome is regarded as a potential therapeutic strategy for many inflammatory diseases. A growing number of studies have identified tanshinone I (Tan I) as a potential anti-inflammatory agent because of its good anti-inflammatory activity. However, its specific anti-inflammatory mechanism and direct target are unclear and need further study. METHODS IL-1β and caspase-1 were detected by immunoblotting and ELISA, and mtROS levels were measured by flow cytometry. Immunoprecipitation was used to explore the interaction between NLRP3, NEK7 and ASC. In a mouse model of LPS-induced septic shock, IL-1β levels in peritoneal lavage fluid and serum were measured by ELISA. Liver inflammation and fibrosis in the NASH model were analyzed by HE staining and immunohistochemistry. RESULTS Tan I inhibited the activation of NLRP3 inflammasome in macrophages, but had no effect on the activation of AIM2 or NLRC4 inflammasome. Mechanistically, Tan I inhibited NLRP3 inflammasome assembly and activation by targeting NLRP3-ASC interaction. Furthermore, Tan I exhibited protective effects in mouse models of NLRP3 inflammasome-mediated diseases, including septic shock and NASH. CONCLUSIONS Tan I specifically suppresses NLRP3 inflammasome activation by disrupting the association of NLRP3 and ASC, and exhibits protective effects in mouse models of LPS-induced septic shock and NASH. These findings suggest that Tan I is a specific NLRP3 inhibitor and may be a promising candidate for treating NLRP3 inflammasome-related diseases.

Abstract
Obesity is an emerging concern globally with increasing prevalence. Obesity is associated with many diseases, such as cardiovascular disease, dyslipidemia, and cancer. Thus, effective new antiobesity drugs should be urgently developed. We synthesized SW20.1, a compound that induces activating transcription factor 3 (ATF3) expression. The results of Oil Red O staining and quantitative real-time polymerase chain reaction revealed that SW20.1 was more effective in reducing lipid accumulation in 3T3-L1 preadipocytes than the previously synthesized ST32db, and that it inhibited the expression of the genes involved in adipogenesis and lipogenesis. A chromatin immunoprecipitation assay indicated that SW20.1 inhibited adipogenesis and lipogenesis by binding to the upstream promoter region of resistin at two sites (-2861/-2854 and -241/-234). In mice, the intraperitoneal administration of SW20.1 reduced body weight, white adipocyte weight in different regions, serum cholesterol levels, adipogenesis-related gene expression, hepatic steatosis, and serum resistin levels. Overall, SW20.1 exerts antiobesity effects by inhibiting resistin through the ATF3 pathway. Our study results indicate that SW20.1 is a promising therapeutic drug for diet-induced obesity.

Abstract
BACKGROUND Tanshinone I (Tan I) is known as one of the important active components in Salvia miltiorrhiza. In recent years, Tan I has received a substantial amount of attention from the research community for various studies being updated and has been shown to possess favorable activities including anti-oxidative stress, regulation of cell autophagy or apoptosis, inhibition of inflammation, etc. PURPOSE: To summarize the investigation progress on the anti-disease efficacy and effect mechanism of Tan I in recent years, and provide perspectives for future study on the active ingredient. METHOD Web of Science and PubMed databases were used to search for articles related to "Tanshinone I" published from 2010 to 2022. Proteins or genes and signaling pathways referring to Tan I against diseases were summarized and classified along with its different therapeutic actions. Protein-protein interaction (PPI) analysis was then performed, followed by molecular docking between proteins with high node degree and Tan I, as well as bioinformactic analysis including GO, KEGG and DO enrichment analysis with the collected proteins or genes. RESULTS Tan I shows multiple therapeutic effects, including protection of the cardiovascular system, anti-cancer, anti-inflammatory, anti-neurodegenerative diseases, etc. The targets (proteins or genes) affected by Tan I against diseases involve Bcl-2, Bid, ITGA2, PPAT, AURKA, VEGF, PI3K, AKT, PRK, JNK, MMP9, ABCG2, CASP3, Cleaved-caspase-3, AMPKα, PARP, etc., and the regulatory pathways refer to Akt/Nrf2, SAPK/JNK, PI3K/Akt/mTOR, JAK/STAT3, ATF-2/ERK, etc. What's more, AKT1, CASP3, and STAT3 were predicted as the key action targets for Tan I by PPI analysis combined with molecular docking, and the potential therapeutic effects mechanisms against diseases were also further predicted by bioinformatics analyses based on the reported targets, providing new insights into the future investigation and helping to facilitate the drug development of Tan I.

Abstract
BACKGROUND Studies have shown that a high-fat diet (HFD) can alter gut microbiota (GM) homeostasis and participate in lipid metabolism disorders associated with obesity. Therefore, regulating the construction of GM with the balance of lipid metabolism has become essential for treating obesity. Salvia miltiorrhiza extract (Sal), a common traditional Chinese medicine, has been proven effective against atherosclerosis, hyperlipidemia, obesity, and other dyslipidemia-related diseases.
AIM To investigate the anti-obesity effects of Sal in rats with HFD-induced obesity, and explore the underlying mechanism by focusing on GM and lipid metabolism.
METHODS Obesity was induced in rats with an HFD for 7 wk, and Sal (0.675 g/1.35 g/2.70 g/kg/d) was administered to treat obese rats for 8 wk. The therapeutic effect was evaluated by body weight, body fat index, waistline, and serum lipid level. Lipid factors (cAMP, PKA, and HSL) in liver and fat homogenates were analyzed by ELISA. The effect of Sal on GM and lipid metabolism was assessed by 16S rRNA-based microbiota analysis and untargeted lipidomic analysis (LC-MS/MS), respectively.
RESULTS Sal treatment markedly reduced weight, body fat index, serum triglycerides (TG), total cholesterol (TC), low-density lipoprotein, glucose, free fatty acid, hepatic lipid accumulation, and adipocyte vacuolation, and increased serum high-density lipoprotein (HDL-C) in rats with HFD-induced obesity. These effects were associated with increased concentrations of lipid factors such as cAMP, PKA, and HSL in the liver and adipose tissues, enhanced gut integrity, and improved lipid metabolism. GM analysis revealed that Sal could reverse HFD-induced dysbacteriosis by promoting the abundance of Actinobacteriota and Proteobacteria, and decreasing the growth of Firmicutes and Desulfobacterita. Furthermore, LC-MS/MS analysis indicated that Sal decreased TGs (TG18:2/18:2/20:4, TG16:0/18:2/22:6), DGs (DG14:0/22:6, DG22:6/22:6), CL (18:2/ 18:1/18:1/20:0), and increased ceramides (Cers; Cer d16:0/21:0, Cer d16:1/24:1), (O-acyl)-ω-hydroxy fatty acids (OAHFAs; OAHFA18:0/14:0) in the feces of rats. Spearman’s correlation analysis further indicated that TGs, DGs, and CL were negatively related to the abundance of Facklamia and Dubosiella, and positively correlated with Blautia and Quinella, while OAHFAs and Cers were the opposite.
CONCLUSION Sal has an anti-obesity effect by regulating the GM and lipid metabolism.

Abstract
Conventional breeding of wild (Cucumis melo var. makuwa Makino (CM)) and cultivated (Cucumis melo var. reticulatus (CR)) melons is aimed at improving their biological traits. Here, we prepared a nontoxic, bioactive extract of vitalmelon (F1 hybrid) and evaluated its antiadipogenic and antiobesity effects in fully differentiated 3T3-L1 adipocytes and high-fat diet- (HFD-) induced obese C57BL/6 mice. In fully differentiated 3T3-L1 adipocytes, the vitalmelon extract reduced the DMI- (dexamethasone, 3-isobutyl-1-methylxanthine, and insulin-) induced increases in lipid droplet number and intracellular glucose and triglyceride levels. In addition, the extract inhibited 3T3-L1 preadipocyte differentiation by downregulating PPAR-γ and target genes LPL, CD36, HMGCR, and L-FABP. To investigate the inhibitory effects of the vitalmelon extract on lipid metabolism, we measured serum lipid, hormone, and cytokine concentrations; lipolytic activity; lipid accumulation; and adipogenesis in HFD-fed mice treated with the extract. The HFD+vitalmelon-fed mice showed lower blood cholesterol, free fatty acid, sugar, leptin, and insulin concentrations but higher blood adiponectin concentrations than the HFD-fed mice. Moreover, the HFD+vitalmelon-fed mice showed lower abdominal fat levels, smaller fat cells, lower weight, and fewer lipid droplets in the liver tissue than the HFD-fed mice. Therefore, in HFD-fed mice, vitalmelon regulated lipid metabolism through PPAR-γ, highlighting its potential as a promising antiobesity functional food.

Abstract
MicroRNAs are small non-coding RNAs that play important roles in gene regulation by influencing the translation and longevity of various target mRNAs and the expression of various target genes as well as by modifying histones and DNA methylation of promoter sites. Consequently, when dysregulated, microRNAs are involved in the development and progression of a variety of diseases, including cancer, by affecting cell growth, proliferation, differentiation, migration, and apoptosis. Preparations from the dried root and rhizome of Salvia miltiorrhiza Bge (Lamiaceae), also known as red sage or danshen, are widely used for treating cardiovascular diseases. Accumulating data suggest that certain bioactive constituents of this plant, particularly tanshinones, have broad antitumor effects by interfering with microRNAs and epigenetic enzymes. This paper reviews the evidence for the antineoplastic activities of S. miltiorrhiza constituents by causing or promoting cell cycle arrest, apoptosis, autophagy, epithelial-mesenchymal transition, angiogenesis, and epigenetic changes to provide an outlook on their future roles in the treatment of cancer, both alone and in combination with other modalities.

Abstract
AIM Increasing brown adipocytes activity and inducting browning of white adipocytes are potential therapeutic targets for the treatment of obesity. In the present study, we investigated the effects of Tanshinone 1 (Tan 1), a major compound from Salvia miltiorrhiza Bunge, on the activation of brown adipocytes and browning of white adipocytes in vivo and in vitro. MATERIALS AND METHODS Expression of genes associated with brown adipocyte function including thermogenesis, mitochondria biogenesis and fatty acid oxidation was examined in brown adipose tissue (BAT) and white adipose tissue (WAT) of high fat diet (HFD)-fed obese mice administrated with Tan 1 or in immortalized brown adipocytes (iBAs) and 3T3-L1 adipocytes treated with Tan 1. Mitochondria DNA (mtDNA) content, lipolysis and phosphorylated AMP-activated protein kinase (AMPK) were further assessed in Tan 1 treated-iBAs and 3T3-L1 adipocytes. KEY FINDINGS The administration of Tan 1 protected against HFD-induced obesity in mice, which was associated with enhanced expression of brown adipocyte function-related genes in BAT and WAT. Tan 1 treatment also upregulated brown adipocyte function-related genes in iBA and induced beige adipocytes genes in 3T3-L1 adipocytes, resulting in increased mtDNA content and lipolysis. Tan 1 activated AMPK in BAT and WAT of HFD-fed obese mice as well as in iBAs and 3T3-L1 adipocytes. Inhibition of AMPK by compound C prevented Tan 1-induced expression of beige adipocytes genes. SIGNIFICANCE These results indicate that Tan 1 activates brown adipocytes and induces browning of white adipocytes, which may contribute to anti-obesity activity of Tan 1.

Abstract
Obesity is not only viewed as a chronic aggressive disorder but is also associated with an increased risk for various diseases. Nonetheless, new anti-obesity drugs are an urgent need since few pharmacological choices are available on the market. Natural compounds have served as templates for drug discovery, whereas modified molecules from the leads identified based on in vitro models often reveal noncorresponding bioactivity between in vitro and in vivo studies. Therefore, to provide inspiration for the exploration of innovative anti-obesity agents, recent discoveries of natural anti-obesity compounds with in vivo evidence have been summarized according to their chemical structures, and the comparable efficacy of these compounds is categorized using animal models. In addition, several synthetic derivatives optimized from the phytochemicals are also provided to discuss medicinal chemistry achievements guided by natural sources.

Abstract
Pharmacological studies indicate that Salvia miltiorrhiza extract (SME) can improve cardiac and blood vessel function. However, there is limited knowledge regarding the effects (exerted through epigenetic regulation) of SME and newly derived single compounds, with the exception of tanshinone IIA and IB, on obesity-induced metabolic disorders. In this study, we administered SME or dimethyl sulfoxide (DMSO) as controls to male C57BL/J6 mice after they were fed a high-fat diet (HFD) for 4 weeks. SME treatment significantly reduced body weight, fasting plasma glucose, triglyceride levels, insulin resistance, and adipogenesis/lipogenesis gene expression in treated mice compared with controls. Transcriptome array analysis revealed that the expression of numerous transcriptional factors, including activating transcription factor 3 (ATF3) and C/EBPα homologous protein (CHOP), was significantly higher in the SME group. ST32db, a novel synthetic derivative similar in structure to compounds from S. miltiorrhiza extract, ameliorates obesity and obesity-induced metabolic syndrome in HFD-fed wild-type mice but not ATF3−/− mice. ST32db treatment of 3T3-L1 adipocytes suppresses lipogenesis/adipogenesis through the ATF3 pathway to directly inhibit C/EBPα expression and indirectly inhibit the CHOP pathway. Overall, ST32db, a single compound modified from S. miltiorrhiza extract, has anti-obesity effects through ATF3-mediated C/EBPα downregulation and the CHOP pathway. Thus, SME and ST32db may reduce obesity and diabetes in mice, indicating the potential of both SME and ST32db as therapeutic drugs for the treatment of obesity-induced metabolic syndrome.

Abstract
The escalation in the global prevalence of obesity has focused attention on finding novel approaches for its management. Ziziphus jujuba Mill. (ZJL) leaf extract is reported as a traditional remedy for diverse pathological conditions, including obesity. The present study investigated whether ZJL affects adipogenic differentiation in human adipocytes. Additionally, following metabolite profiling of the extract, apigenin (APG), betulinic acid (BA) and maslinic acid (MA) were selected for biological activity evaluation. The possible interactions between APG, BA, MA and target proteins with a central role in adipogenesis were assessed through molecular docking. The potential mechanisms of ZJL, APG, BA and MA were identified using transcriptional analysis through real-time quantitative PCR and protein abundance evaluation by Western blotting. The obtained results revealed a concentration-dependent reduction of accumulated lipids after ZJL, BA and MA application. The key adipogenic transcription factors peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT-enhancer-binding protein alpha (C/EBPα) were strongly decreased at a protein level by all treatments. Moreover, the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway was found to be involved in the anti-adipogenic effect of ZJL, APG and BA. Collectively, our findings indicate that ZJL and its pure compounds hampered adipocyte differentiation through PI3K/AKT inhibition. Among the selected compounds, BA exhibits the most promising anti-adipogenic activity. Furthermore, being a complex mixture of phytochemicals, the ZJL extract could be utilized as source of yet unknown bioactive leads with potential implementation in obesity management.

Abstract
Objective Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. As a traditional medicine, Salvia miltiorrhiza (S. miltiorrhiza) has been widely used in the treatment of many gynecological diseases, but the efficacy of S. miltiorrhiza in women with PCOS has not been assessed. The purpose of this systematic review and meta-analysis was to evaluate the effectiveness and safety of S. miltiorrhiza in women with PCOS. Methods We conducted searches in PubMed, Embase, the Cochrane Library, the China National Knowledge Infrastructure, the Wanfang Database, the Chinese Scientific Journal Database, and the Chinese BioMedical database from inception to December 23, 2020, to identify studies that met the inclusion criteria. The quality of the evidence was estimated using the Cochrane Reviewer Handbook 5.0.0, and the meta-analysis was performed using RevMan 5.3.5 software. Results Six randomized controlled trials (RCTs) involving 390 patients with PCOS were included. The studies suggested that S. miltiorrhiza extract combined with letrozole (LET) was more effective in improving pregnancy rate (RR: 2.60, 95% CI: 1.06 to 6.39, P=0.04) compared to LET alone. S. miltiorrhiza extract was associated with decreased fasting blood glucose (MD: –0.25, 95% CI: –0.37 to –0.13, P < 0.0001), fasting insulin (MD: –1.16, 95% CI: –1.74 to –0.58, P < 0.0001), total cholesterol (TC) (MD: –0.58, 95% CI: –0.72 to –0.43, P < 0.00001), and triglycerides (TG) (MD: –0.31, 95% CI: –0.35 to –0.26, P < 0.00001) compared with placebo, but not with improvements in body mass index or waist-to-hip ratio (MD: –1.41, 95% CI: –4.81 to 2.00, P=0.42; MD: –0.02, 95% CI: –0.05 to 0.01, P=0.16, respectively). There was a significant difference between S. miltiorrhiza extract combined with cyproterone acetate (CPA) and CPA alone in terms of decreasing TC (MD: –0.77, 95% CI: –0.89 to –0.65, P < 0.00001), TG (MD: –0.43, 95% CI: –0.65 to –0.20, P < 0.0001), and low-density lipoprotein cholesterol (MD: –0.49, 95% CI: –0.66 to –0.33, P < 0.00001) and increasing high-density lipoprotein cholesterol (MD: 0.30, 95% CI: 0.20, 0.40, P < 0.00001). In addition, S. miltiorrhiza extract also decreased testosterone, follicle-stimulating hormone, and luteinizing hormone. The studies did not mention any adverse events with S. miltiorrhiza extract. Conclusion The current studies indicate that S. miltiorrhiza has beneficial effects on reproduction and glucose and lipid metabolism in patients with PCOS, and it is generally safe for clinical application. However, more prospective RCTs with large samples, multiple centers, and longer intervention duration are needed in the future to obtain more reliable conclusions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Obesity is one of the growing public health problems in Turkey, as well as all over the world, threatening people of almost all ages. Turkey has a large potential for research on this topic due to owning broad ethnomedicinal experience and the richest flora (34% endemic) of Europe and the Middle East. Herbs that they have utilized for centuries to treat and prevent obesity can provide useful options to overcome this issue. AIM OF THE STUDY This survey was carried out to disclose the inventory of plant taxa that the people of Turkey have been using for a few centuries in treating obesity without any side effects or complications, and to compare them with experimental studies in the literature. MATERIALS AND METHODS The research was achieved in two phases on the matter above by using electronic databases, such as Web of Science, ScienceDirect, Scopus, ProQuest, Medline, Cochrane Library, EBSCO, HighWire Press, PubMed and Google Scholar. Both results were shown in separate tables as well as the regional comparative analysis. RESULTS 117 herbal taxa belonging to 45 families were identified among the selected 74 studies conducted in the seven regions of Turkey. However, only 49 (41.9%) of them were found to be subjected to worldwide in vitro and in vivo research conducted on anti-obesity activity. Quercetin (9.1%), gallic acid (6.1%) and ferulic acid and epigallocatechin gallate (4.5%) have been recorded as the most common active ingredients among the 66 active substances identified. Prunus avium (32.4%) and Rosmarinus officinalis (25.7%) were identified as the most common plants used in Turkey. Also, Portulaca oleracea and Brassica oleracea emerged as the most investigated taxa in the literature. CONCLUSION This is the first country-wide ethnomedical review conducted on obesity treatment with plants in Turkey. Evaluating the results of the experimental anti-obesity research conducted in the recent years in the literature, it was determined that forty-nine plants were verified. This clearly shows that these herbs have a high potential to be a pharmacological resource. Moreover, 68 (41.9%) taxa, which haven't been investigated yet, are likely to be a promising resource for national and international pharmacological researchers in terms of new natural medicine searches.
