Objective: To observe the anti-oxidation capacity of Radix Astragali Polysaccharide. Method:Ageing models of mice and atherosclerosis models of rabbit made with D-galactose were used to test. Result: Radix Astragali polysaccharide obviously promoted the activity of SOD, CAT and GSH-Px in blood, and reduced LPO level in plasma, liver homogenize and brain homogenize in ageing mice,and also positively decrease the levels of TG,TC,LDL-C,ApoA,ApoB,MDA and TRAC, but oppositely increased the levels of SOD and HDL-C in blood of atherosclerosis model rabbits. Conclusion: Radix astragali polysaccharide has good capacity for of anti-oxidation, so it can be endowed with ability to resist and atherosclerosis.
