Abstract:
Objective: The effects of purple-fleshed sweet potato anthocyanin (PSA) on anti-oxidation and anti-aging were investigated. Methods: The effects of different doses of PSA(100、 500、1000 mg/kg bw)on the serum T-AOC were investigated in aged mice after administration for 3 d, 10 d and 18 d. The content of MDA, the activity of serum SOD and blood GSH-Px were measured, and compared with those in Vit E and control group after 30 d. Result: PSA significantly increased the serum T-AOC in aged mice, and this increment was higher when given longer. PSA significantly decreased MDA and enhanced SOD and GSH-Px activities. The efficiency on antioxidative capacity of aged mice at PSA 100 mg/kg bw was equivalent to that of vitamin E at the same amount (100 mg/kg bw). The antioxidation state of 13 mo mice given PSA at 1000 mg/kg bw was near to that of 4 mo mice. Conclusion: PSA has marked effect of antioxidation and can delay aging.
