Purification, in-depth structure analysis and antioxidant stress activity of a novel pectin-type polysaccharide from Ziziphus Jujuba cv. Muzaoresidue

Ziziphus Jujuba cv. Muzao has attracted researchers for a long time, while residue of jujuba after extracted by water still contains many bioactivities. This paper presents the first study on in-depth structure analysis and its antioxidant of a pectic polysaccharide (PZJRP) separated and purified from Ziziphus Jujuba cv. Muzao residue through alkali extraction. Results of structural and morphological characterization according to...
