Synergistic antiaging effects of jujube polysaccharide and flavonoid in D-Galactose-Induced aging mice

Abstract

In this study, the synergistic effects of jujube polysaccharide (JP) and flavonoid (JF) on aging mice were investigated. Sub-acutely aging mouse models were established using D-galactose. Eighty experimental mice were randomly assigned to normal, model, vitamin C (200 mg/kg), JP (200 mg/kg), JF (200 mg/kg) and JP + JF (low (100 mg/kg), medium (200 mg/kg), and high-dose (300 mg/kg)) groups (10 mice in per group). After 35 days, the physiological aging indices of mice were measured. JP and JF displayed significantly positive synergistic antiaging effects. Compared with an aging model control group, groups administered JP and JF showed increased indices for the thymus and spleen and significantly increased activities of SOD and GSH-PX in the heart, liver, spleen, and brain (R² > 0.99, P < 0.01; R² > 0.98, P < 0.01). The contents of MDA in heart, liver, spleen, brain and serum were significantly decreased (R² > 0.95, P < 0.01), while those of HYP in skin and serum were significantly increased. The concentrations of neurotransmitters (NE, DA, 5-HT, 5-HIAA) in the brain and serum of mice were significantly increased (P < 0.01). These results indicated that JP and JF acted not only on relevant tissues or organs of mice, but on all body systems.
