Qi Kang, Guangda Xia, Gangliang Huang, Hualiang Huang
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.
