Antioxidant activity of oligosaccharide ester extracted from Polygala tenuifolia roots in senescence-accelerated mice

Figures & data

Figure 1.  The HPLC fingerprints of resin-fractionated YZ oligosaccharide esters (YZ-OE) and the chemical structure of 3,6′-disinapoyl sucrose.

Figure 2.  Effect of resin-fractionated YZ oligosaccharide ester and its component, 3,6′-disinapoyl sucrose, on the content of SOD, GSH-PX, MDA in serum of SAMP and SAMR mice. Values are presented as mean ± SEM of the results from eight mice. Significance was determined at **P <0.01 (*P <0.05, two way ANOVA) versus model group and ^##P <0.01 (^#P <0.05, two way ANOVA) versus normal control.

Figure 3.  Effect of resin-fractionated YZ oligosaccharide ester and its component, 3,6′-disinapoyl sucrose, on the content of SOD, GSH-PX, MDA in liver of SAMP and SAMR mice. Values are presented as mean ± SEM of the results from eight mice. Significance was determined at **P <0.01 (*P <0.05, two way ANOVA) versus model group and ^##P <0.01 (^#P <0.05, two way ANOVA) versus normal control.
