Abstract
AbstractPueraria lobata polysaccharides (PLPs) were obtained by hot water extraction using Pueraria lobata as raw material. Structural analysis revealed that PLPs may have a repetitive backbone units of →4) ‐α‐D‐Glcp (1→4‐α‐D‐Glcp (1→. Phosphorylated Pueraria lobata polysaccharides (P‐PLPs), carboxymethylated Pueraria lobata polysaccharides (CM‐PLPs) and acetylated Pueraria lobata polysaccharides (Ac‐PLPs) were obtained by chemical modifications of PLPs, respectively. The physicochemical properties and antioxidant activities of these four Pueraria lobata polysaccharides were studied in comparison. In particular, the clearance rate of P‐PLPs exceeded 80 %, and was expected to achieve the same effect as Vc. The results showed that the effects of different chemical modifications on the antioxidant activity of PLPs varied greatly.
