Abstract:
The Daucus carota polysaccharides were extracted by hot water extraction and alcohol precipitation, and the phosphorylated and carboxymethylated derivatives were prepared. Their structures were characterized by FT-IR, NMR, and SEM. The antioxidant activities of Daucus carota polysaccharide were enhanced by phosphorylation. However, carboxymethylated Daucus carota polysaccharide was not as good as unmodified one.
