Preparation and Performance Evaluation of Polysaccharide-Iron Complex of Eucommia ulmoides.

An innovative iron supplement crucial for treating iron-deficiency anemia was developed in this study. Polysaccharide was extracted from Eucommia ulmoides leaves using a microwave-assisted hot water method, and subsequently, the polysaccharide-iron complex was synthesized through co-thermal synthesis with FeCl3. The physicochemical properties, structure, and thermal stability of the complex were analyzed using FE-SEM, SEC-MALLS, FT-IR, XRD, and DSC techniques. Furthermore, the antioxidant activity of the polysaccharide-iron complex was evaluated through an experiment in vitro. The results revealed that the polysaccharide-iron complex had an iron content of 6.1% and an average particle size of 860.4 nm. The microstructure analysis indicated that the polysaccharide-iron complex possessed a flaky morphology with smooth and compact surfaces. Moreover, the formation of the Fe3+ complex did not alter the structural framework of the polysaccharide; instead, it enhanced the polysaccharide's thermal stability. Compared to traditional iron supplements, the E. ulmoides-derived polysaccharide-iron complex demonstrated significant antioxidant activity. Therefore, this novel compound exhibits significant potential as a viable iron supplement.

Preparation of Rehmanniae Radix Praeparata Polysaccharide Iron(III) Complex and Evaluation of Its Biological Activity.

This study extracted and purified a polysaccharide from Rehmanniae radix praeparata (RGP) with an average molecular weight. The structural characteristics of RGP and its iron (III) complex, RGP-Fe(III), were examined for their antioxidant properties and potential in treating iron deficiency anemia (IDA). Analysis revealed that RGP comprised Man, Rha, Gal, and Xyl, with a sugar residue skeleton featuring 1→3; 1→2, 3; and 1→2, 3, 4 linkages, among others. RGP-Fe(III) had a molecular weight of 4.39×104 Da. Notably, RGP-Fe(III) exhibited superior antioxidant activity compared to RGP alone. In IDA rat models, treatment with RGP-Fe(III) led to increased weight gain, restoration of key blood parameters including hemoglobin, red blood cells, and mean hemoglobin content, elevated serum iron levels, and decreased total iron-binding capacity. Histological examination revealed no observable toxic effects of RGP-Fe(III) on the liver and spleen. These findings suggest the potential of RGP-Fe(III) as a therapeutic agent for managing IDA and highlight its promising antioxidant properties.

The total clinical efficacy was higher in study group (p &lt; 0.05), and the incidence of adverse pregnancy outcomes was lower (p &lt; 0.05).Conclusions: The combination of PIC with vitamin C significantly improves the hematological indices, enhances iron metabolism, and reduces adverse pregnancy outcomes compared to PIC alone in pregnant women with IDA. Further studies with larger sample sizes are warranted to validate these results.

Efficacy of polysaccharide iron complex in IDA rats: A comparative study with iron protein succinylate and ferrous succinate

Iron deficiency anemia (IDA) is the most common nutrient-related health problem in the world. There is still a lack of comprehensive comparative study on the efficacies of commonly used iron supplements such as polysaccharide iron complex (PIC), iron protein succinylate (IPS) and ferrous succinate (FS) for IDA. In this study, we compared the PIC, IPS and FS efficacies in IDA rats via intragastric administration. The results showed that the three iron supplements had similar efficacies. PIC/IPS/FS at a dose of 15 mg Fe/kg/d for 10 d increased the hematological and serum biochemical parameters to 2.15/2.12/2.18 (Hb), 1.71/1.67/1.69 (RBC), 2.10/2.11/2.12 (HCT), 1.26/1.22/1.22 (MCV), all 1.34 (MCH), 1.15/1.15/1.14 (MCHC), 1.94/1.82/1.91 (SF), 9.75/9.67/9.53 (SI), and 23.30/22.68/21.64 (TS) times, and reduced TIBC to 0.42/0.43/0.44 times, compared to untreated IDA rats. PIC performed slightly better than IPS and FS in restoring MCV level. Meanwhile, the heart, spleen and kidney coefficients reduced to 67%/74%/65% (heart), all 59% (spleen) and 87%/88%/88% (kidney), and the liver coefficient increased to 116%/115%/116%, compared to untreated IDA rats. The liver iron content was found to be more affected by IDA than the spleen iron content. PIC/IPS/FS at 15 mg Fe/kg/d increased organ iron contents to 4.20/3.97/4.03 times (liver) and 1.36/1.24/1.41 times (spleen) within 10 d compared to untreated IDA rats, and PIC-H and FS were slightly better than IPS in restoring spleen iron content. The results of this study can provide useful data information for the comparison of three iron supplements, PIC, IPS and FS.

Preparation, Biological Activities, and Application of Plant Polysaccharide Iron Complexes: A Review

AbstractIron is an essential trace element in the human body. Iron deficiency can lead to iron deficiency anemia (IDA) and induce various diseases. Hence, it is urgent to find an iron supplement with minimal side effects and good iron supplementation effect. Natural polysaccharides from plants have various biological activities such as antioxidant, hypoglycemic, immunomodulatory, etc. Increasing research has shown that polysaccharides modified with iron can enhance their biological activities. Among them, polysaccharide iron complex (PIC) has significant anti‐anemia activity. With the powerfully development of PIC, increasing research has found that PIC showed some advantages, including good water solubility, high bioavailability, low gastrointestinal irritation, and high iron content. Therefore, PIC has received widespread attention. Currently, PIC is widely used in various fields such as agriculture, animal husbandry, and clinical treatment. However, there are limited reports on the preparation, biological activities, and applications of PIC. This paper systematically reviews the preparation methods, iron content determination methods, biological activities, and applications of PIC. The results provide important references for the deep development and utilization of PIC.

Flammulina velutipes polysaccharide-iron(III) complex used to treat iron deficiency anemia after being absorbed via GLUT2 and SGLT1 transporters

Iron deficiency anemia (IDA) is a common nutritional problem, but traditional iron supplements cause many adverse reactions. Thus, the development of a novel iron supplement might be significant for the treatment of IDA. This study aimed to study the transport mechanism of Flammulina velutipes polysaccharide-iron complex (FVP1-Fe(III)) in Caco-2 cells and the therapeutic effect on IDA rats, as well as the influence on gut microbiota in vivo. These results showed that in vitro, the uptake of FVP1-Fe(III) was mediated by sodium-dependent glucose transporter-1 (SGLT1) and facilitated glucose transporter-2 (GLUT2) and GLUT2 played a dominant function. The multidrug resistance-associated protein-2 (MRP-2) was involved in the efflux of FVP1-Fe(III) across the Caco-2 cells. In vivo, FVP1-Fe(III) had a better restorative effect on blood parameters and iron status indicators in rats with IDA as compared with FeSO4 and exerted this effect by downregulating the expression of hepcidin. FVP1-Fe(III) could also regulate gut microbiota dysbiosis in iron deficiency rats by returning the relative abundance of gut microbiota to the normal level. Besides, as a dietary factor, vitamin C (vit C) could enhance the therapeutic effect of FVP1-Fe(III). These present findings showed that FVP1-Fe(III) could be exploited as a novel iron supplement to treat IDA.

Preparation, characterization, antioxidant and antianemia activities of Poria cocos polysaccharide iron (III) complex

As a new natural antioxidant with high safety and non-toxic side effects, polysaccharide can also be used as a critical macromolecular carrier to form a stable iron complex with Fe3+. Our previous study has extracted and purified the homogeneous polysaccharide (PCP1C) from Poria cocos. In this study, the PCP1C-iron (III) complex was synthesized by co-thermal synthesis with PCP1C and ferric trichloride. The chelating capacity, iron releasing capacity, and qualitative identification of complex were evaluated. The complex was characterized by scanning electron microscope-energy dispersive spectrometer (SEM-EDS) analysis, particle size distribution, and fourier transform infrared (FTIR) spectroscopy. The antioxidant and iron supplement effects of the complex were also studied in vitro and in the iron deficiency anemia (IDA) rat model. The results showed that the iron content in the PCP1C-iron (III) complex was 28.14% with no free iron, and the iron release rate was 95.3%. The structure analysis showed that the iron core of the PCP1C-iron (III) complex existed in the form of β-FeOOH and the surface of the complex become smooth and particle size increased, which indicated the high iron content of polysaccharide iron and slow release. Furthermore, we found that the PCP1C iron (III) complex had positive scavenging effect on DPPH, ABTS, MDA, and hydroxyl radical in vitro study and significantly increased the levels of red blood cell (RBC), Hemoglobin (Hb), and red blood cell specific volume (HCT) in IDA rat model. Therefore, our results suggested that the PCP1C-iron (III) complex is expected to develop into a new comprehensive iron supplement and antioxidant.

Antioxidant and Biological Activities of the Lotus Root Polysaccharide-Iron (III) Complex.

In this study, the synthesis parameters of the lotus root polysaccharide iron complex (LRPF) were determined and optimized by response surface methodology. Under the optimum preparation conditions, the pH of the solution was 9, the ratio of M (trisodium citrate): m (lotus root polysaccharide) was 0.45, the reaction time was 3 h. UV spectroscopy, thermogravimetry, FT-IR spectroscopy, X-ray diffraction, CD, and NMR were used for the characterization of the LRPF. LRPF has good stability and easily releases iron ions under artificial gastrointestinal conditions. LRPF exhibited antioxidant activity in vitro and can significantly improve the antioxidant activity in vivo. In addition, LRPF has a good effect in the treatment of iron deficiency anemia in model mice, impacts the gut microbiome, and reduces the iron deficiency-induced perniciousness by regulating steroid hormone biosynthesis. Therefore, LRPF can be used as a nutritional supplement to treat and prevent iron-deficiency anemia and improve human immunity.

Structural characterization and biological activities of polysaccharide iron complex synthesized by plant polysaccharides: A review.

Iron deficiency anemia can lead to a variety of functional disorders, which is one of the highest incidence of nutrient deficiency diseases. The direct addition of iron to food will not only brings difficulties to the production of products, but also brings damages to human body. In recent years, international studies have shown that polysaccharide iron complex (PIC) not only has a variety of pharmacological activities of polysaccharide itself, but also has the function of supplementing iron, so it is a good iron supplement. With the advantages of good solubility, high iron content, low gastrointestinal irritation and high bioavailability, PIC is an effective iron supplement for iron deficiency anemia and has attracted more and more attention. In this paper, the different preparation methods, structural characterization, biological activities and clinical applications of PIC synthesized by natural polysaccharides from plant were reviewed, in order to provide theoretical basis for the development and application of PIC.

Characterisation and antioxidant activity of polysaccharide iron (III) complex in Qingzhuan Dark Tea

Anaemia, caused by iron deficiency, is a common disease in some parts of the world. A traditional medicine for treating anaemia resulting from iron deficiency is inorganic iron, which is represented by ferrous sulfate. However, serious irritation to the gastrointestinal tract is one of the side effects caused by inorganic iron. We extracted the tea polysaccharide (TPS) from Qingzhuan Dark Tea and employed a green technology to prepare a polysaccharide–iron [TPS-Fe(III)] complex. We further characterised the structure through thermogravimetric analysis, molecular weight analysis, atomic absorption spectroscopy, Fourier-transform infrared spectroscopy, ultraviolet spectroscopy (UV), 1H nuclear magnetic resonance spectroscopy, scanning electron microscopy, X-ray diffraction analysis, X-ray photoelectron spectroscopy, and atomic mechanics microscopy. We performed a comparative evaluation of the antioxidant properties of the TPS-Fe(III) complex and TPS. The results indicated that the antioxidant activity of the TPS-Fe(III) complex is superior to that of TPS. The scavenging activity was determined using 2,2-diphenyl-1-picrylhydrazyl, hydroxyl, superoxide anion, and 2,2'-azobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity assays and malondialdehyde inhibition assay. The structure of the TPS-Fe(III) complex formed by the complexation of the tea polysaccharide with iron ions was highly stable, which significantly improved its antioxidant activity in vitro. Thus, the TPS-Fe (III) complex can provide additional health benefits compared with other typical non-antioxidant iron nutritional supplements.

Efficacy and safety of polysaccharide iron complex capsules compared with iron sucrose in hemodialysis patients: study protocol for a randomized, open-label, positive control, multicenter trial (IHOPE)

BackgroundAnemia is one of the main complications of chronic kidney disease especially kidney failure, which includes treatment with erythropoiesis-stimulating agents and iron supplementation, including intravenous and oral iron. However, intravenous iron may pose limitations, such as potential infusion reactions. Oral iron is mainly composed of divalent iron, which can excessively stimulate the gastrointestinal tract. Iron polysaccharide complex capsules are a novel oral iron trivalent supplement with higher iron content and lower gastrointestinal irritation. However, since high-quality evidence-based medicinal support is lacking, it is necessary to conduct clinical studies to further evaluate the effectiveness and safety of oral iron polysaccharide complex in chronic kidney disease patients.MethodsThis randomized controlled trial uses an open-label, parallel group design, where the efficacy and safety of maintenance hemodialysis (MHD) participants is evaluated. The experimental group is assigned erythropoietins and iron polysaccharide complex (two capsules each time, bid), and the control group is assigned erythropoietin and sucrose iron (100mg, 2w) injection. Participants (aged 18–75 years) undergoing maintenance hemodialysis were considered for screening. Inclusion criteria included hemoglobin (Hb) ≥110g/L and < 130g/L, transferrin saturation (TSAT) > 20% and < 50%, and serum ferritin (SF) > 200μg/L and < 500μg/L. Exclusion criteria included acute or chronic bleeding, serum albumin < 35g/L, hypersensitive C-reactive protein (HsCRP) > 10 mg/L, and severe secondary hyperparathyroidism (iPTH ≥ 800 pg/mL). Full inclusion and exclusion criteria are described in the “Methods” section. The primary endpoint is TSAT of the participants at week 12. Secondary endpoints include Hb, SF, hematocrit (Hct), HsCRP, pharmacoeconomic evaluation, drug costs, quality of life, and indicators of oxidative stress. The treatment will last for 24 weeks with a follow-up visit at baseline (within 7 days prior to initial treatment) and weeks 4, 8, 12, 16, 20, and 24 after initial treatment. This clinical research includes 9 hemodialysis centers in mainland China and plans to enroll 186 participants.DiscussionIt is expected that it will provide strong evidence to reveal the clinical efficacy and safety of oral iron in the treatment of chronic CKD-related anemia in MHD patients through this clinical trial.Trial registrationChinese Clinical Trial Registry ChiCTR2000031166.

A water extraction and alcohol precipitation method was applied to extract polysaccharides from Codonopsis pilosula (CPP), response surface methodology was used to optimize the extraction conditions and synthesis of C. pilosula polysaccharide iron (CPPI), and the properties of CPPI were evaluated. The optimum extraction conditions for CPP were as follows: liquid-solid ratio of 29.39 mL/g, time of 1.25 h and temperature of 62.84 °C. The optimum synthesis conditions for CPPI were pH 8.9, temperature 70.30 °C and the ratio of citric acid to CPP1 of 2.95. An HPSEC-MALLS-RID system, UV spectroscopy, FT-IR spectroscopy and NMR were used for characterization of the polysaccharide. CPPI exhibited antioxidant activity in vitro and a relatively strong inhibitory effect on A2780 cells growth. After CPPI treatment, the reactive oxygen species increased, the mitochondrial membrane potential decreased, and DNA damage was observed in A2780 cells. Therefore, CPPI should be explored as a potential antioxidant and an antitumor drug in a clinical setting.

Cyclic voltammetry: a simple method for determining contents of total and free iron ions in sodium ferric gluconate complex

&lt;p class="PaperAbstract"&gt;Sodium ferric gluconate complex (SFGC) is the third generation of iron supplement of polysaccharide iron (III) complex (PIC). For evaluation of technological level and application value of the prepared SFGC, it would be of great significance to determine the iron content in SFGC in a simple but effective way. This paper introduces the cyclic voltammetry (CV) method for determination of iron content in SFGC. Under established optimal experimental conditions, the content of free iron ions can be directly scanned and calculated, while the total iron content can also be determined by completely acidifying SFGC into Fe&lt;sup&gt;3+&lt;/sup&gt; ions. After optimizing and screening, the optimal scanning conditions are determined as pH 3 and 0.05 V/s of the scanning rate. Prior CV measurements, 0.4 V of the enrichment potential, and 3 min of the enrichment time are found optimal. It has also been verified that CO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;2-&lt;/sup&gt; ions present in the solution show little interference in the system within the experimental range of investigation. The contents of free Fe&lt;sup&gt;3+&lt;/sup&gt;, Fe&lt;sup&gt;2+&lt;/sup&gt; ions and the total iron determined after acid-hydrolysis of SFGC can be accurately calculated according to the corresponding linear relationships between peak currents and iron concentrations. In this paper, the repeatability and accuracy of the method are verified, and its feasibility as a convenient and effective method to determine the iron supplements is confirmed.&lt;/p&gt;

Structural characteristics and antioxidant activity of polysaccharide-iron complex from Glehniae Radix

ABSTRACT The preparation conditions of Glehniae Radix polysaccharide-iron complex (GLP80-Fe) were optimized and the physicochemical properties were characterized by Ultraviolet-visible spectroscopy (UV-Vis), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), Transmission electron microscope (TEM), Thermogravimetric analyzer, and Differential scanning calorimetry (TGA-DSC), respectively. The stability and reducibility of GLP80 and GLP80-Fe were analyzed, and the monosaccharide composition was determined by gas chromatograph (GC). In vitro antioxidant activity of GLP80 and GLP80-Fe were evaluated by determining the radical (DPPH and hydroxyl radical) scavenging abilities. The results showed that the highest iron content of GLP80-Fe (15.61%±0.04) was obtained at the optimum conditions: reaction temperature was 38.0°C, reaction time was 3.0 h, FeCl3 addition was 2.9 mL and pH was 9. GLP80-Fe was a complex with β-FeOOH as the core and polysaccharides on its surface, and it was stable at pH 3 ~ 14. GC showed that the major monosaccharides were mannose (Man) and galactose (Gal) with a ratio of 1:5.15. In vitro free-radical scavenging activity of GLP80-Fe was significantly better than GLP80. The IC50 of GLP80-Fe against DPPH and hydroxyl radical were 3.785 mg/mL and 1.460 mg/mL, respectively.

Preparation and Characterization of a Novel Polysaccharide-Iron(III) Complex in Auricularia auricula Potentially Used as an Iron Supplement.

Iron deficiency anemia has been a widespread disease. As an effective and stable iron supplement, the physiochemical properties of the polysaccharide iron complex have been widely studied. In this study, we characterized a novel polysaccharide-iron(III) complex extracted in an edible fungal species Auricularia auricular (AAPS-iron(III)). The highest iron content (28.40%) in the AAPS-iron(III) complex was obtained under the optimized preparation conditions including an AAPS to FeCl3∙6H2O ratio of 2:3 (w/w), a pH value of 8.0 in solution, a reaction temperature of 50°C, and a reaction time of 3 h. The physical and chemical properties of the AAPS-iron(III) complex were characterized by qualitative and quantitative analyses using scanning electron microscope, particle size distribution, thermogravimetric analyzer, Fourier transform infrared spectroscopy, circular dichroism, and 1H nuclear magnetic resonance. Result showed that, although the iron was bound to the polysaccharide, it was released under artificial gastrointestinal conditions. The AAPS-iron(III) complex exhibited high stability (under 50-256°C) and water solubility. The AAPS-iron(III) complex also showed high antioxidant activity in vitro, demonstrating an additional health benefit over other typical nonantioxidant iron nutritional supplements. Furthermore, the AAPS-iron(III) complex showed high efficiency on the treatment of the iron deficiency anemia in the model rats. Therefore, the AAPS-iron(III) complex can be used as a nutritional fortifier to supply iron in industrial processing and to assist the treatment of iron deficiency anemia.

Antioxidant, immunomodulatory, oxidative stress inhibitory and iron supplementation effect of Astragalus membranaceus polysaccharide-iron (III) complex on iron-deficiency anemia mouse model.

As iron supplement, the antioxidant activities of APS-iron (III) complex were comprehensively evaluated by 5-axe cobweb charts, which indicated the APS-iron (III) complex had a certain antioxidant activity and been weaker than that of APS. The results of immunological activity experiments indicated the stimulation index increased with APS-iron (III) complex concentration increase. When the concentration of the APS-iron (III) complex was 50 μg/mL, the lymphocytes proliferation increased by 35.7% compared with APS. APS-iron (III) complex also had better complement fixing activity than APS, 0.589 mg/mL of which achieved 50% complement fixing activities. Through the iron supplement experiments on iron-deficiency anemia mouse model, we found the APS-iron (III) complex faster increased hemoglobin concentration, SOD, CAT and faster decreased MDA to the normal level than Niferex and ferrous sulfate. Histological results revealed that the tissue sections were clear without obvious pathological changes and bone marrow had most hematopoietic cells from APS-iron (III) complex rat group, which also proved the APS-iron (III) complex had no significant side effects. Therefore, APS-iron (III) complex may be developed as a multifunctional iron supplement for clinical application.
