Summary: This study investigated the cellulase-assisted extraction of Chinese yam polysaccharides and determined the optimal conditions. Three polysaccharide fractions were purified and analyzed, with CYP3 showing the strongest antioxidant activity. Methylation and NMR analysis were used to elucidate the detailed structure of CYP3. The results suggest that CYP3 could be utilized as an antioxidant in food processing, pharmaceuticals, and other applications.

Summary: Selenylation Astragalus polysaccharides (Se-APS) were successfully prepared using an optimized microwave-assisted method. The Se-APS exhibited high selenium content and showed improved antioxidant capacities compared to Na2SeO3. The release of selenium from Se-APS was higher in intestinal fluid than in gastric fluid.

Summary: The traditional Chinese medicine Notopterygium incisum is commonly used to treat rheumatoid arthritis, and polysaccharides from N. incisum may be its main active components. In this study, a novel polysaccharide named NIP was extracted from N. incisum, which showed potential anti-inflammatory and anti-oxidative stress effects. In vitro and in vivo experiments demonstrated NIP's ability to inhibit inflammatory factors, activate signaling pathways, and restore intestinal flora imbalance, suggesting that NIP could be recommended as a functional food for rheumatoid arthritis.

Summary: In this study, two homogeneous polysaccharides (APS-A1 and APS-B1) were isolated from Astragalus membranaceus and their chemical structures were characterized. APS-A1 had a 1,4-alpha-D-Glcp backbone with a 1,4,6-alpha-D-Glcp branch every ten residues, while APS-B1 was a heteropolysaccharide composed of glucose, galactose, and arabinose. Bioactivity assays showed that both APS-A1 and APS-B1 exhibited potential anti-inflammatory activity.

Summary: Microwave-assisted enzymatic extraction (MAEE) was used to separate polysaccharides from micro-Chlorella. The extraction conditions were optimized using Box-Behnken design and response surface methodology. The optimal condition for extracting crude polysaccharides (CSCP) from Chlorella sp. was found to be at 50 degrees C for 2.3 h with 380 W of microwave power and 0.31% of enzyme dosage. The extraction yield of CSCP reached 0.72% under these conditions. Additionally, the modification conditions with α-amylase were optimized, and the enzyme-modified CSCP showed a typical heteropolysaccharide composition.

Summary: Phellinus spp., an important medicinal fungus mushroom cultivated and consumed in East Asia for over 2000 years, has polysaccharides as major bioactive macromolecules with multiple health-promoting effects. While extraction and purification methods, structural characteristics, and pharmacological activities of these polysaccharides have been extensively studied, there is limited knowledge on their structures and bioactivity relationship, toxicologic effects, and pharmacokinetic profile. This review systematically summarizes recent progress in the isolation and purification, chemical structures, bioactivities, and underlying mechanisms of PPs, providing insights for their further development as therapeutic agents and functional foods.

Summary: This study characterized IDF from three sources and found that they have different morphologies and compositions. Carrot IDF showed stronger water holding capacity, enoki mushroom IDF had better glucose adsorption, and oat IDF had stronger cholesterol adsorption. None of the three IDFs significantly inhibited starch digestion.
