Lv, Qing-Qing published the artcileStructural characterization, α-amylase and α-glucosidase inhibitory activities of polysaccharides from wheat bran, Category: alcohols-buliding-blocks, the main research area is alphaamylase alphaglucosidase glucose galactose arabinose wheat bran; Polysaccharide; Structural characterization; Wheat bran; α-Amylase; α-Glucosidase.
In this study, two polysaccharide fractions were isolated from wheat bran by sequential extraction with water and alk. solution, DEAE Cellulose-52 chromatog. and Sephacryl S-400 gel permeation chromatog., they were named as WXA-1 and AXA-1, resp. Structural analyses indicated that both polysaccharide fractions were heteropolysaccharides, their average mol. weights were 193 kDa and 107 kDa, resp. The backbone of WXA-1 was → 4-β-D-Xylp-1→, which was substituted at O-3 positions by arabinose, glucose and galactose residues, while the backbone of AXA-1 was → 4-β-D-Xylp-1→, which was mainly substituted at O-3 positions by arabinose. AXA-1 exerted a stronger inhibitory effect on the activities of α-amylase and α-glucosidase compared with WXA-1. Moreover, AXA-1 exhibited a competitive inhibition of α-amylase and a mixed-type noncompetitive inhibition of α-glucosidase. These results suggest that AXA-1 can be used as α-amylase and α-glucosidase inhibitors.
