Effects of Ethanol Concentrations on Primary Structural and Bioactive Characteristics of Dendrobium officinale Polysaccharides

Nutrients, Journal Year: 2024, Volume and Issue: 16(6), P. 897 - 897

Published: March 20, 2024

Ethanol fractional precipitation can initially separate polysaccharides according to the structure, which exhibits strong correlation with biological activities. This study aimed investigate impact of varying ethanol concentrations on structural characteristics, and antitumor antioxidant activities derived from Dendrobium officinale through precipitation, as well their internal relationships. The acquired by absolute alcohol additions at a final liquor-ethanol volume ratio 1:1, 1:2, 1:4 were named DOP-1, DOP-2, DOP-4, supernatant was DOP-S. results analysis revealed that increase in resulted reduction molecular weights acetylation degree polysaccharides, decrease mannose content an glucose content. In vitro experiments demonstrated DOP-S exhibited optimal Animal further confirmed suppressed growth solid tumors significantly, enhanced lymphocytes, mediated immune ability, improved activity enzymes. These findings would establish theoretical foundation provide technical support for advances applications D. fields food medicine.

Immunomodulation of Glycyrrhiza Polysaccharides In Vivo Based on Microbiome and Metabolomics Approaches

Foods, Journal Year: 2025, Volume and Issue: 14(5), P. 874 - 874

Published: March 4, 2025

Glycyrrhiza uralensis Fisch. is a medicinal herb that can be added to food provide therapeutic effects and reduce the burden of medications. Herein, immunomodulatory polysaccharides (GPs) were verified illustrated by intervening immunocompromised rats treated with different doses GPs, which reflected for adjusting composition structure intestinal microbiota altering metabolic profile. The GPs exerted regulating microenvironment. In particular, could promote growth probiotic bacteria Allobaculum, norank__o_Clostridia_UCG-014, Dubosiella, g__norank_o___RF39 curb harmful Enterococcus. results showed had prebiotic effect, contributed improving environment maintaining health. addition, content beneficial differential metabolites was up-regulated, especially short-chain fatty acids, alanine, aspartate, glutamate metabolism; arginine biosynthesis; glyoxylate dicarboxylate metabolism being most enriched pathways. These pathways imply process effector it are focused. Overall, purpose this article lies in providing support application immune function.
