Abstract:

The aim was to isolate and purify the polysaccharide components in Dangsengwujia, analyze the structure of the components through experiments, and analyze their antioxidant bioactivity. The polysaccharides named ASP were isolated and purified from the stems of Acanthopanax sessiliflorus, and their structural characteristics were studied and analyzed by high performance liquid chromatography, gas chromatography-mass spectrometry, Fourier transform infrared, ultraviolet-visible spectroscopy, 1H NMR and 13C NMR. The antioxidant activities and iron ion reduction ability of polysaccharide of ASP to 1,2-dipicyl-2-trinitrophenylhydrazine (DPPH), and 2,2-biazo-bis (3-ethyl-benzothiazol-6-sulfonic acid) ammonium salt (ABTS) were evaluated. The experimental results show that the polysaccharide of ASP is composed of mannose, glucose, galactose and arabinose, and its structure is mainly composed of pyranose rings. It can effectively scavenge DPPH, ABTS cation free radicals, reduce iron ions, and show a certain antioxidant capacity. The polysaccharides from ASP have good antioxidant bioactivity.

Key words: Acanthopanax sessiliflorus, polysaccharide, anti-oxidation, structural analysis, bioactivity analysis
