摘要
The antioxidant activities of polysaccharide from balsam pear were studied. It was determined by gel permeation chromatography that the molecular weight distribution of purified polysaccharide was concentrated near 33582 Da. It indicated that the monosaccharide components were rhamnose, galacturonic acid, galactose, xylose and arabinose. Fourier transform infrared spectroscopy, nuclear magnetic resonance and Congo red experiments showed that there are C1, C2, C3, C5 links, and stable β-triple helix conformation in aqueous solution. It was found that polysaccharide had good scavenging effect on free radicals. So, balsam pear polysaccharide should be a potential antioxidant.
