|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Beneficial effects of neomangiferin on high fat diet-induced nonalcoholic fatty liver disease in rats.[Pubmed: 25661699]|
|This study was carried out to determine the effect and mechanism of action of Neomangiferin (NG) on high-fat diet-induced nonalcoholic fatty liver disease (NAFLD) in rats. NAFLD rats were randomly assigned into several groups of equal number. Neomangiferin (50, 25mg/kg·day(-1) BW) and lipanthyl (PT, 5mg/kg·day(-1) BW) were given to the NAFLD rats, respectively. In the study, serum lipids, metabolic rate, liver fat, liver lipids and histology were examined. To further investigate the molecular mechanism of the effect of Neomangiferin on NAFLD, expression levels of mRNA and protein for peroxisome proliferator-activated receptor α (PPARα), fatty acid transport protein 2 (FATP2), long-chain-fatty-acid - CoA ligase 1 (ACSL1) and carnitine palmitoyltransferase 1a (CPT1a) in the liver were determined by Real Time-PCR and western blot analysis, respectively. Neomangiferin administration significantly reduced the final body weight, liver fat accumulation, and serum triglyceride (TG), total cholesterol (TC) concentrations, low-density lipoprotein cholesterol (LDL-C), glucose (GLU) levels, and hepatic TG, TC, malondialdehyde (MDA) levels, but increased serum high-density lipoprotein cholesterol (HDL-C) and hepatic superoxide dismutase (SOD) levels. Neomangiferin upregulated the mRNA and protein expression of PPARα and CPT1a, but downregulated the mRNA and protein expression of FATP2 and ACSL1 in the liver. These results suggested that Neomangiferin can regulate NAFLD partly by modulating the expression levels of genes involved in FFA uptake and lipid oxidation.|

|Preparative isolation of neomangiferin and mangiferin from Rhizoma anemarrhenae by high-speed countercurrent chromatography using ionic liquids as a two-phase solvent system modifier.[Pubmed: 19950352]|
|A preparative high-speed countercurrent chromatography method for isolation and purification of Neomangiferin and mangiferin from Rhizoma anemarrhenae was successfully established by using ionic liquids as the modifier of the two-phase solvent system. Neomangiferin and mangiferin were purified from the crude extract of R. anemarrhenae by using ethyl acetate-water-[C(4)mim][PF(6)] (5:5:0.2 v/v) as two-phase solvent system. In total, 22.5 mg of Neomangiferin and 70.6 mg of mangiferin were obtained from 150 mg of the crude extract. The purities of Neomangiferin and mangiferin were 97.2 and 98.1%, respectively, as determined by HPLC. The chemical structures of the isolated compounds were identified by (1)H-NMR and (13)C-NMR.|

|On-line purity monitoring in high-speed counter-current chromatography: application of HSCCC-HPLC-DAD for the preparation of 5-HMF, neomangiferin and mangiferin from Anemarrhena asphodeloides Bunge.[Pubmed: 17349768]|
|An efficient on-line purity monitoring strategy based on on-line coupling of high-speed counter-current chromatography (HSCCC) with high-performance liquid chromatography-diode array detection (HPLC-DAD) was successfully applied for the first time to the isolation and purification of 5-hydroxymethyl-furancarboxaldehyde (5-HMF), mangiferin and Neomangiferin from the Chinese medicinal plant Anemarrhena asphodeloides Bunge, a plant used in the traditional Chinese medicine.From 600 mg partially purified extract, 165.6 mg Neomangiferin and 292.8 mg mangiferin with purities of 98.9 and 99.5%, respectively, were obtained with a two-phase solvent system composed of n-butanol-water (1:1, v/v) by increasing the flow-rate of the mobile phase stepwise from 1.0 to 2.2 ml min(-1) after 210 min. A 17.1mg 5-HMF with purity of 96.6% was also isolated for the first time.|

|Neomangiferin modulates the Th17/Treg balance and ameliorates colitis in mice.[Pubmed: 26926174 ]|
|Neomangiferin suppressed retinoic acid receptor-related orphan receptor gamma t (RORγt) and IL-17 expression in IL-6/transforming growth factor β-stimulated Th17 splenocytes and increased IL-10 expression in vitro. Mouse TNBS-induced colon shortening, macroscopic score, and myeloperoxidase activity were inhibited by Neomangiferin, which also reduced TNBS-induced activation of nuclear factor-κB and extracellular signal-regulated kinases, as well as expression of inducible nitric oxide synthase and cyclooxygenase-2. In addition, Neomangiferin inhibited TNBS-induced expression of tumor necrosis factor-α, IL-17, IL-6, and IL-1β, and increased IL-10 expression. Neomangiferin inhibited TNBS-induced differentiation to Th17 cells and promoted the development of Treg cells. Moreover, in IL-10(-/-) mice, Neomangiferin inhibited colonic myeloperoxidase activity, suppressed Th17 cell differentiation, and reduced levels of TNF-α and IL-17. CONCLUSION: Neomangiferin may restore the balance between Th17/Treg cells by suppressing IL-17 and RORγt expression and inducing IL-10 and forkhead box P3 expression, thus ameliorating colitis.|
