Structural Characterization and Antioxidant Properties of a Novel Polysaccharide Isolated from .

In this investigation, a novel heteropolysaccharide, denoted as PS-HW1, is isolated from . The achieved PS-HW1 polymer exhibits a molecular weight of 1.22 × 10 kDa and composes the residues of d-glucose, d-fructose, and d-galactose in a 1:1:2 ratio.

An insight into the antioxidant activities and the exploration of record high quantities of quercetin and luteolin in the plant parts of (wall.) Blume.

This study attempts to reveal antioxidants in the plant parts of (Wall.) Blume using antioxidant assays and LC-MS/MS analysis. Methanol is the most effective solvent for collecting antioxidants.

Rich d-Fructose-Containing Polysaccharide Isolated from Roots toward a Superior Antioxidant Biomaterial.

The presented study attempts to unveil and evaluate the antioxidant activity of a novel heteropolysaccharide separated from the roots of (denoted as PS-MSR). The molecular weight of PS-MSR is found to be 1.88 × 10 Da and contains two principal sugars, which are d-glucose and d-fructose, in the backbone.

Structural Characterization of Mannoglucan Isolated from and Its Antioxidant Activities.

A novel polysaccharide structure (PS-T80) was collected from biomass and characterized via a combination of chemical and spectral analyses. Employing high-performance gel permeation chromatography (HPGPC), the average molecular weight is proven to be 7.4 × 10 Da.
