- •
A novel polysaccharide from pulp tissues of Annona squamosa.
- •
The structural characterization of ASPW80-1 was conducted.
- •
A novel modified polysaccharide namely ASPW80-M1 was also synthesized.
- •
The ultrastructure of ASPW80-1 and ASPW80-M1 was investigated by scanning electron microscope (SEM) and atomic force microscopy (AFM).
- •
Antioxidant and immunostimulatory activities of ASPW80-1 and ASPW80-M1 were evaluated.
