“…After the introduction of Cr(III), most of the characteristic peaks were similar to PPP, demonstrating that the main functional groups were not changed after complexation with Cr(III). How-ever, the peaks of stretching vibration of O-H showed a red shift from 3380 to 3394 cm −1 , indicating the formation of a coordination bond between O-H and Cr(III) [13]. Furthermore, the new characteristic absorption peak of Cr-O appeared at 534 cm −1 in PPP-Cr(III), showing that Cr(III) participated in the complexation reaction [18].…”

“…However, Zhang et al, (2020) reported that the relative molecular weight of Fritillaria ussuriensis polysaccharide remains unchanged basically after zinc modification [34]. Jia et al, (2021) reported that the Mw of corn silk polysaccharide was significantly increased compared with its iron, zinc, or chromium complexes, which showed that metal ions, like a binder, promoted the connection of polysaccharide [13]. In this work, the initial pH was ~3.9, and the final pH was 6.8 using a 1 mol/L NaOH solution, which may be due to introducing NaOH solutions to cleave the glycosidic linkages adjacent to methoxy groups of GalA units of polysaccharides to decrease Mw.…”

Additionally, this difference in molecular weight may be related to the characteristics of different polysaccharides and their complexes [13].…”

“…In addition, the absorbance of PPP-Cr(III) solution was higher than PPP solution in the range of 200-250 nm, indicating that O-H and C=O in polysaccharides maybe participated in the complex formation with Cr(III) and oxygens might be the ligating atoms between Cr(III) and polysaccharides (o→Cr and oxo→Cr) (Figure 1A) [35,36]. In contrast, the absorbance of Cr(III) and corn silk polysaccharide complex was decreased distinctly, which may be because the complex of corn silk polysaccharide and Cr(III) caused a reduction in the conjugated system [13]. Thus, it is speculated that the complexing forms of Cr(III) and different polysaccharides are different.…”

“…In recent years, polysaccharides have been widely used as a nanocarrier for oral delivery systems due to their low toxicity and high biocompatibility [11]. Furthermore, some studies have also confirmed that the biological activities of polysaccharides can be improved after chemical modification, such as selenium, chromium, zinc, and iron complex formation [12,13]. Chromium (Cr) is an essential component in humans and animals, which is involved in the metabolism of carbohydrates, proteins, lipids, and nucleic acids in the body [14].…”

The aim of our study was to synthesize a pumpkin peel polysaccharide (PPP)-Cr(III) complex and investigate its hypoglycemic activity. Firstly, a novel PPP-Cr(III) complex with a Cr content of 23.77 mg/g was synthesized and characterized. Physicochemical characterization indicated that PPP-Cr(III) had some changes in chemical composition, monosaccharide composition, and morphological structure compared with PPP. The molecular weights of PPP-Cr(III) and PPP were 1.398 × 106 g/mol and 3.386 × 106 g/mol, respectively, showing a lower molecular weight after the introduction of Cr(III). Fourier transform infrared spectroscopy showed that a new characteristic absorption peak of Cr-O appeared at 534 cm−1 in PPP-Cr(III), indicating that Cr(III) was successfully complexed with PPP. Secondly, the hypoglycemic activity of PPP-Cr(III) based on α-glucosidase inhibitory and insulin resistance (IR)-HepG2 cells was evaluated. Compared with PPP, PPP-Cr(III) exhibited a more significantly α-glucosidase inhibitory activity. The IR-HepG2 cells confirmed an obvious increase in glucose consumption. Western blot analysis demonstrated that the treated IR-HepG2 cells were able to increase the protein levels of p-AMPK and p-GSK-3β, indicating that IR-HepG2 cells exerted hypoglycemic activity via the AMPK/GSK-3β signaling pathway. These results suggested that PPP-Cr(III) had good hypoglycemic activity, which could provide theoretical support for the development of novel hypoglycemic products.

The objective of this study is to employ an adsorption technology to remove methylene blue from the aqueous solution. Methylene blue is one of the dyestuffs that are discharged to wastewater after being used extensively in the industry and creating pollution. A residue of an agricultural product called corn silk was employed in the adsorption process, along with corn silk that had been sulphuric acid‐treated. Using methods like FT‐IR, SEM, EDX, and TGA, the structures of crude corn silk (CCS) and modified corn silk (MCS) were clarified. The ideal adsorption conditions for both adsorbents were found to be equilibrium contact period, pH, the dose of adsorbent, and beginning methylene blue concentration. At 293, 313, and 333 K, adsorption kinetic and isotherm experiments were conducted. It was determined that both adsorptions were compatible with the pseudo‐second‐order kinetic model kinetically and the Freundlich isotherm model isothermally with higher R2 values. At 333 K, the maximum adsorption capacities (qm) of CCS and MCS were calculated to be respectively 59.5 mg g−1 and 400 mg g−1. The findings demonstrated that although crude corn silk adsorbs methylene blue, sulphuric acid treatment greatly increases its adsorption ability.

Iron 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.
