The aim of this study was to investigate whether the therapeutic effect theabrownin extracted from Qingzhuan tea (QTB) on metabolic dysfunction-associated steatosis liver disease (MASLD) is related regulation intestinal microbiota and its metabolite short-chain fatty acids (SCFAs). Mice were divided into four groups received normal diet (ND), high-fat (HFD) HFD+QTB (180, 360 mg/kg) for 8 weeks. results showed that QTB significantly reduced body weight HFD mice, ameliorated lipid...
The paradoxical effects of cobalt in biological processes have caused controversy regarding the application cobalt-based biomaterials. Cobalt has recently been shown to be a trace element that promotes bone growth. Qingzhuan Dark Tea polysaccharides (TPS) biomaterial with antioxidant and immunomodulatory effects. In order develop novel biomaterial, we synthesized polysaccharide complex (TPS-Co) prevent while maintaining its beneficial effects, evaluated morphology, structure, activity....
Several vascular embolization materials are commonly used in clinical practice, however, having application defects of varying degrees, such as poor intraoperative imaging and easy recanalization embolized blood vessels, they challenging for during Transcatheter arterial (TAE). Thus, an visible material with good effect biocompatibility can improve transcatheter efficacy to some extent. Our study aimed synthesize a novel that achieve complete trunks peripheral namely poly (N-isopropyl...
Anaemia, caused by iron deficiency, is a common disease in some parts of the world. A traditional medicine for treating anaemia resulting from deficiency inorganic iron, which represented ferrous sulfate. However, serious irritation to gastrointestinal tract one side effects iron. We extracted tea polysaccharide (TPS) Qingzhuan Dark Tea and employed green technology prepare polysaccharide–iron [TPS-Fe(III)] complex. further characterised structure through thermogravimetric analysis,...
To produce Qingzhuan dark tea polysaccharide–zinc (TPS–Zn), polysaccharides (TPS) were isolated from and complexed with a zinc salt in the present study. The thermogravimetric analysis, molecular weight atomic absorption spectrum, Fourier transform infrared ultraviolet scanning electron microscope, X-ray diffraction, photoelectron spectroscopy, mechanical microscope used for qualitative quantitative characterisation. findings demonstrated verified that complex reactions between ions TPS had...
Qingzhuan dark tea polysaccharides (QDTP) have been complexed with Zinc (Zn) to form the polysaccharides-Zinc (QDTP-Zn) complex. The present study investigated protective effects of QDTP-Zn on ulcerative colitis (UC) in mice. UC mouse model was induced using dextran sodium sulfate (DSS), followed by oral administration (0.2 and 0.4 g kg
The effective selenylated polysaccharides (refer as TPS-Se) with an average molecular weight (MW) of 3.109 × 104 Da was synthesized by the reduction sodium selenite ascorbic acid in presence Qingzhuan Dark Tea (TPS). selenium (Se) content TPS-Se up to 37.05%. differences between TPS and were compared morphology, structure, antioxidant activity, using FT-IR, Raman spectroscopy, X-ray diffraction (XRD), photoelectron spectroscopy (XPS), SEM, AFM, Integrated thermal gravimetric analysis....
To establish a fast, sensitive and accurate high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for determining the monosaccharide content of Qingzhuan Dark Tea polysaccharides in different years (2 years, 5 11 years).The optimised chromatographic conditions were achieved on C18 column (5.0 μm, 250 mm × 4.6 inner diameter). The mobile phase flow rate was 0.9 mL/min temperature set to 27°C. aqueous A (5 mM ammonium acetate) organic B (acetonitrile) used elute...
Tea polysaccharides was one of the active ingredients Qingzhuan dark tea, which had antioxidant, anti-tumor, and immune-enhancing effects. The complexation metal ions tea current research hotspots. It can combine advantages their complexed trace elements, great potential development. In this study, element-copper required by human body used for with polysaccharides, structure characterized various chemical methods. copper complexes were UV spectroscopy, FT-IR, thermogravimetric analysis,...
Iodized oil has an excellent X-ray imaging effect, but it shows poor embolization performance. When used as embolic agent, is easily washed off by the blood flow and eliminated from body. Therefore, essential to use iodized in combination with solid agents such gelatin sponge or perform multiple procedures achieve therapeutic effect. In present study, a poly(N-isopropyl acrylamide)-co-acrylic acid (PNCAA) temperature-sensitive nanogel was synthesized emulsion polymerization; then emulsified...
Fractures occur commonly with multiple injuries, and their incidence has increased in recent years. Trace amounts of cobalt are necessary for many living organisms as it stimulates hematopoiesis improves bone health. However, is also toxic, might cause allergic reactions tissue destruction. These factors limit the application some medical fields. We studied tea polysaccode-cobalt complex (TPS-Co) prepared from Qingzhuan Dark Tea polysaccharides. used 6-week-old Sprague-Dawley rats to...
