Yang, Yanmin published the artcileStructural characterization and antioxidant activities of one neutral polysaccharide and three acid polysaccharides from Ziziphus jujuba cv. Hamidazao: A comparison, Application of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Ziziphus Hamidazao neutral acid polysaccharide antioxidant anticancer agent; liver cancer; Antioxidant; Comparison; Polysaccharide; Structural characterization; Ziziphus jujuba cv. Hamidazao.
A neutral polysaccharide (HJP-1a) and three acid polysaccharides (HJP-2, HJP-3 and HJP-4) were obtained from Z. jujuba cv. Hamidazao. HJP-1a was mainly composed of arabinose and galactose in a ratio of 56.9:20.0, with an average mol. weight of 3.115 x 104 g/mol. HJP-2, HJP-3 and HJP-4 were homogeneous heteropolysaccharides mainly containing galacturonic acid, arabinose and galactose, with average mol. weights of 4.590 x 104, 6.986 x 104 and 1.951 x 105 g/mol, resp. Structural characterization indicated that the backbone of HJP-3 appeared to be mainly composed of →4-alpha-D-GalpA (1→ and →2,4)-alpha-L-Rhap (1→ residues with some branches consisting of →5)-alha-L-Araf 1→ residues and terminals of T-alpha-L-Araf 1→ and T-beta-D-Galp residues. The four purified fractions displayed dose-dependent radical scavenging activity on ABTS+ radicals and reducing capacity, as well as excellent protective effect on H2O2-induced HepG2 cells and metronidazole-damaged zebrafish embryos, especially HJP-2 in vitro and HJP-1a in vivo. Therefore, the polysaccharides from Z. jujuba cv. Hamidazao could be used as a potential antioxidant in functional foods.
