In this paper, Fritillaria pallidiflora schrenk polysaccharides were extracted with different methods and isolated by anion-exchange and gel-permeation chromatog. Physicochem. properties, structural characteristics and antioxidant activities were investigated for the first time. The polysaccharides composed of glucose, galactose, arabinose, xylose, mannose and rhamnose with different molar ratio and mol. weight Fourier transform IR spectroscopy and NMR anal. exhibited the presence of key functional groups of polysaccharides whereas SEM anal. revealed the characteristic morphol. of different fractions. The thermogravimetric anal. manifested the thermal stability of polysaccharides. The reducing power and antioxidant activities of polysaccharides were evaluated in vitro. Among them, the acidic fraction FPSP-H2-1 has a strong antioxidant effect against DPPH, hydroxyl and ABTS free radicals. The results revealed the polysaccharide’s important role as potential natural antioxidant agents during the investigation and application of bioactive polysaccharide.
