摘要: 目的 研究黄芪总提取物(total extract of astragalus,TEA)延缓衰老的作用机理。方法 采用小鼠D-半乳糖(D-galactose,D-gal)人工衰老模型和自然衰老模型(17mon),从氧自由基代谢方面进行研究。结果 TEA(40mg·kg-1·d-1ig ×10 wk)可明显降低D-gal衰老小鼠过高的MDA 含量,上调其过低的抗氧化酶(GSHPX、Mn-SOD)活性和GSH/GSSG比值。TEA(40mg·kg-1·d-1ig×3mon)对17mon小鼠亦有类似作用。结论 TEA对D-gal衰老小鼠和由中年期(14mon)进入老前期(17mon)小鼠的自然衰老进程有明显的延缓作用,可能与其抗氧化作用有关。

Abstract: Aim To study the mechanism of the anti-aging effect of total extract of astragalus(TEA) in mice.Methods MDA content, the activities of Mn-SOD and GSHpx and the reduced to oxidized glutathione (GSH/GSSG)ratio in mitochondria of D-galactose(D-gal)treated mice and 17-month-old mice were measured.Results Treatment with TEA(40 mg·kg-1·d-1ig)for 10wk would lower the content of MDA and restore activities of Mn-SOD, GSHpx and GSH/GSSG ratio in mitochondria of D-gal treated mice.Treatment with TEA (40mg·kg-1·d-1 ig)for 3 mon had the same effect on 17-month-old mice.Conclusion TEA has anti-aging effect on D-gal treated mice and 17-month-old mice significantly, probably being related to its anti-oxidative effect.
