Physicochemical properties, structure, growth-promoting and antioxidant activities of Glycyrrhiza leaf polysaccharides modified by fermentation

Chemical and Biological Technologies in Agriculture, Journal Year: 2025, Volume and Issue: 12(1)

Published: Jan. 14, 2025

This study aimed to investigate the effects of fermentation on physicochemical properties and in vitro antioxidant activities Glycyrrhiza leaf, compare structures unfermented (GLP) fermented (FGLP) polysaccharides, assess their growth-promoting using zebrafish embryos. The results showed that polysaccharide content, extract yield, reduced sugar content leaf increased significantly after 36 h fermentation. In parallel, assays demonstrated for exhibited strong DPPH, hydroxyl radical scavenging, reducing power. Scanning electron microscope infrared spectroscopy analyses revealed differences surface morphology with both polysaccharides being acidic containing pyranose rings α-glycosidic bonds. molecular weight FGLP was lower than GLP, molar ratios guluronic acid, amino glucose, glucuronic xylose, arabinose were increased. model, promoted growth development embryos, most pronounced effect at a concentration 20 µg/mL superior protective against lipid peroxidation cell death induced by 2,2′-azobis (2-methylpropionamidine) dihydrochloride. findings could enhance utilization capacity. These opened avenues further research into bioavailability vivo offered valuable insights its potential as natural innovative antioxidant. Highlights

Chemical characterization, antioxidant activity and activation of macrophages RAW264.7 viaMAPK signaling pathway of the exopolysaccharide from Penicillium EF‐2

Journal of the Science of Food and Agriculture, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

Abstract BACKGROUND Microbial exopolysaccharides represent a significant source of polysaccharides, with their production unconstrained by temporal or spatial limitations. Penicillium , filamentous fungus widely recognized for its medicinal food applications, is known to produce that exhibit cancer‐inhibitory properties. RESULTS In the present study, from EF‐2 (EPS) were extracted and structurally characterized using ion chromatograph, infrared spectroscopy NMR. The in vitro antioxidant immunomodulatory activities also investigated. EPS has molecular weight 111.47 kDa, primarily composed mannose, glucose galactose, possesses crystalline region, exhibits excellent thermal free radical scavenging assays, demonstrated robust activity. Furthermore, activated mitogen‐activated protein kinase pathway, enhancing capacity macrophages. CONCLUSION biological activities. study provides theoretical basis utilization offers new ideas active sources fermented foods. © 2025 Society Chemical Industry.

Ultrasonics Sonochemistry, Journal Year: 2025, Volume and Issue: unknown, P. 107315 - 107315

Published: March 1, 2025

Konjac is a perennial herbaceous plant from the Araceae family's Amorphophallus genus. It has high nutritional, health, and pharmacological values. contains various bioactive components, most notable of which konjac glucomannan, several biological roles, including efficiently fighting diabetes, exerting prebiotic activity, containing antioxidant capacity, modulating immunological function, demonstrating anti-cancer potential. Currently, glucomannan (KGM) research mainly focuses on packaging film, gel characteristics, efficacy, evaluation. However, extraction, underlying portrayal, derivatization, action KGM are seldom detailed. Herein, utilization as an unrefined substance was surveyed, meaning to give extensive orderly recombinant data decontamination, structure, natural movement, use provide full play interesting gelatinate, biocompatibility, viscosity other properties KGM. provided theoretical basis for further developing food industry, pharmaceutical field, fields.

The antioxidant activity of shaddock peel polysaccharides

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 21, 2025

The shaddock peel polysaccharide (SPP) has various biological activities. This explored its antioxidant activity. In vitro tests, the two SPP components showed good DPPH, hydroxyl radical scavenging ability and anti-lipid peroxidation ability. At a concentration of 3.2 mg/mL, abilities polysaccharides were 21.65% 18.96%, respectively. SPP-3 had slightly stronger to scavenge radicals than SPP-2. When reached order polysaccharides' DPPH rates was SPP-2 > SPP-3. Therefore, strong activity could be used in antioxidant-related applications future.
