ISOLATION AND STRUCTURAL AND CHEMICAL ANALYSIS OF PECTINIC POLYSACCHARIDES FROM Amaranthus cruentus

摘要

Pectinic polysaccharides were isolated and characterized for the first time from the aerial part of Amaranthus cruentus L. The structural and chemical characteristics of the pectinic polysaccharides were analyzed by NMR, IR, HPLC, and AFM. It was shown that amaranth pectin had a linear α-1,4-D-galacturonan portion and branched rhamnogalacturonan regions. The neutral sugars were Rha, Ara, Gal, and Xyl.
