Pumpkin Polysaccharide Extracted by Subcritical Water: Physicochemical Characterization and Anti‐Diabetic Effects in T2DM Rats

Molecular Nutrition & Food Research (2022)

Yongrui Ti Weizhen Wang Xiaoxiao Wang Yüqian Ban Peng Wang

This study aims to optimize the extraction of pumpkin polysaccharide by subcritical water, investigates the physicochemical properties and biological activities of pumpkin polysaccharide.Subcritical water is used to extract pumpkin polysaccharide. The structure and composition of pumpkin polysaccharide are analyzed by infrared spectroscopy, gel filtration chromatography, and high-performance liquid chromatography. The hypoglycemic and hypolipidemic potential of pumpkin polysaccharide aere determined by the physicochemical indexes, pathological, and immunohistochemical analysis in T2DM rats induced by STZ + high-fat diet. The optimal conditions for subcritical water are 1:15, 150°C, and 10 min. Pumpkin polysaccharide has α-configurations and are mainly composed of seven different monosaccharides, and it exhibits good free-radical scavenging ability and inhibition of α-amylase, α-glucosidase, and pancreatic lipase activities. Pumpkin polysaccharide treatment in T2DM rats significantly decreases the concentrations of blood glucose, insulin, TC, TG, LDL-C, and MDA; increases the levels of HDL-C; and enhances the antioxidant enzymes activities (SOD and CAT). Histopathology and immunohistochemical analyses reveal that pumpkin polysaccharide has protective effects on kidney and pancreatic organs in T2DM rats.Pumpkin polysaccharide extracted by SWE shows great potential as functional food ingredients and candidates for T2DM treatment.

A magnetic nanocomposite combined with cinnamic acid for capture–inhibition–separation of Aspergillus fumigatus

Food Frontiers (2023)

Zihan Song Yanli Zhang Yongrui Ti Huitian Qiao Chen Niu

Abstract To prevent the generation of drug‐resistant fungi from long‐term exposure to microorganisms, cinnamic acid (CA), a natural effective antifungal agent, was successfully coupled with poly‐dopamine magnetic nanoparticles (CA–DMPs). Due to the low solubility of CA, the saturated solution of CA (1.61 mg/mL, 45°C) had no antifungal effect. Contrarily, CA–DMPs showed a good antifungal effect. The resulting heat‐stable and reusable antifungal CA–DMP composite particles were superparamagnetic (49.79 emu g −1 ) and had an average diameter of 25.01 ± 1.36 nm. The novel composites showed good antifungal activity and excellent recycling performance, the sterilization rate of CA–DMPs remained above 96% after seven consecutive running cycles. CA–DMP composites could damage the fungal cell wall and membrane system, leading to the leakage of cell inclusions. Furthermore, transcriptome analysis of Aspergillus fumigatus treated with composites showed that 466 differentially expressed genes were primarily associated with cell wall membrane, membrane transporters, energy metabolism, genetic expression, and oxidation–reduction. The effect of CA–DMPs in inducing mitochondrial membrane dysfunction might result in the disruption of energy metabolism and REDOX homeostasis. Overall, the results reported herein provide new insight into the potential antifungal nanomaterials. In vitro antifungal experiments performed on cherry tomatoes confirm the application potential of the synthesized material in the field of fruit and vegetable preservation.

Systematic evaluation on the physicochemical characteristics of a series polysaccharides extracted from different edible lilies by ultrasound and subcritical water

Frontiers in Nutrition (2022)

Zihan Song Yanli Zhang Yulin Luo Yongrui Ti Weizhen Wang

A series polysaccharide samples extracted from three edible lilies (Lilium davidii var. willmottiae, Lilium brownii var. viridulum, and Lilium lancifolium) by subcritical water and ultrasound-assisted extraction were systematically compared. The results showed that extraction method was a more important factor than lily species. Subcritical water extracted lily polysaccharides (S-LP) with higher yield, molecular weight, neutral glucose and uronic acid content as well as apparent viscosity. Ultrasound-assisted extracted lily polysaccharides (U-LP) with higher reducing sugars and protein content. Moreover, due to the degradation of glycosidic bonds, ultrasonic extraction was easier to obtain lower molecular weight polysaccharides. In addition, the extraction method significantly affected the monosaccharide proportion of polysaccharides, but had no effect on type. Glucose was the main component in S-LP, and glucose and mannose were the main components in U-LP. The micromorphology of different polysaccharide samples was similar, and the scanning electron microscope (SEM) images showed regular/irregular particle clusters with different particle sizes. Overall, the relationships between extraction methods, lily species and polysaccharide properties were preliminarily elucidated, providing a reference for the targeted extraction of specific lily polysaccharides (LP).
