  • Objectives： Polygonati Rhizoma (PR) has containing the bioactive compounds such as poly sccharide A,B,C, oligosaccharide, amino acid, it has reported to anti-diabetes and hypertension, atherosclerosis. In this study, we were evaluates antioxidant and anti-physical fatigue effects of PR and steamed PR.Methods : The sample was divided into 5 groups-PR0 (PR without steaming process), PR1 (PR with once steaming process), PR3 (PR with third steaming process), PR6 (PR with sixth steaming process), PR9 (PR with ninth steaming process). We measured anti-oxidant activity through contents of polyphenol, flavonoid and DPPH, ABTS free radical scavenging capacity. And, anti-physical fatigue effect was evaluated using the swimming test, and the AMPK protein expressions in soleus muscle.Results ： As a result, polyphenol, flavonoid, DPPH, ABTS free radical scavenging capacity of PR were increased as steaming times. Anti-physical fatigue effects by swimming test, PR0 have significantly increased, but steamed PR groups were decreased. The AMPK protein expressions of PR0 and PR1 groups were increased comparing with PR3, PR6 and PR9. All groups had effects on decreasing TG, creatine in blood serum, but had no effects on TC in blood serum.Conclusions ： In conclusion, PR with 9 steaming process was more excellent than not-processed PR in anti-oxidant effect such as DPPH, ABTS radical scavenging activity and contents of polyphenol, flavonoid, but, not-processed PR increased swimming times than processed PR. These results suggest that processed PR has anti-oxidant effect as steaming times, and not-processed PR may be a novel potential anti-physical fatigue agents than processed PR.
