Li, Lingyu published the artcileStructural characterization and antioxidant activities of one neutral polysaccharide and three acid polysaccharides from the roots of Arctium lappa L.: A comparison, Computed Properties of 59-23-4, the main research area is Arctium root polysaccharide antioxidant; Antioxidant ability; Arctium lappa L.; Comparison; Polysaccharide; Structural characterization.
In this work, we comparatively analyzed the structure and antioxidant activities of different polysaccharide fractions from Arctium lappa L. A total of four water-soluble polysaccharide fractions (ALP-1, ALP-2, ALP-3 and ALP-4) were obtained from the roots of Arctium lappa L. They differed in monosaccharide composition, mol. weight and linkage mode. ALP-1 and ALP-2 mainly consisted of fructose, with average mol. weights of 2.676 x 103 and 2.503 x 104 g/mol, resp. ALP-3 and ALP-4 were mainly composed of fructose, arabinose and galactose, with average mol. weights of 9.709 x 104 and 6.790 x 104 g/mol, resp. Furthermore, Fourier transform IR spectrometry, methylation anal. and NMR spectroscopy suggested that the main polysaccharide ALP-1 had a linear chain of (1 → 2)-linked β-D-Fructofuranosyl backbone (n ≈ 15) linked to a terminal (1 → 2)-linked α-D-Glucopyranosyl at the non-reducing end. All five polysaccharides displayed high antioxidant ability, especially ALP-4 in H2O2-induced HepG2 cell model and ALP-1 in metronidazole [MET]-induced zebrafish model. These findings provided comparative information on the structure and biol. activity of different burdock polysaccharides and highlighted their potential as antioxidants in functional foods.
