A pectic polysaccharide (named CMDP-4b) with a molecular weight of 31.97 kDa was extracted from Cucurbita moschata Duch and purified by column chromatography. On the basis of methylation, Fourier-transform infrared, monosaccharide composition, and one- and two-dimensional nuclear magnetic resonance spectroscopy analyses, the structure of CMDP-4b was determined to be composed of an α-1,4-linked homogalacturonan backbone, which was slightly acetylated and highly methyl-esterified, and branched at the O-3 position of the →4)-α-D-GalpA-6-OMe-(1→.
