Abstract
A monomeric polysaccharide isolated from-(), and a preparation method and use thereof are provided. The monomeric polysaccharide includes xylose, glucuronic acid, galactose, glucose, and mannose. The present disclosure further provides a structure and a preparation method of the monomeric polysaccharide isolated from, and the preparation method adopts a plurality of chromatographic techniques. The monomeric polysaccharide isolated fromin the present disclosure is high-acetyl glucuronoxylogalactoglucomannan. The monomeric polysaccharide can reduce percentages of eosinophils, neutrophils, and lymphocytes in a lung lavage solution of a SiOdust-induced silicosis model mouse, significantly reduce levels of oxidative and inflammatory factors such as SOD, HYP, IL-6, and TNF-α in a SiOdust-induced silicosis model group in a dose-dependent manner, exhibit a protective effect for an experimental SiOdust-induced silicosis model mouse.
