Abstract:
Object To investigate and compare the scavenging effect of Cordyceps growing in different environment on hydroxyl radical. Methods 10-Phennanthroline-Fe 2+ oxidative assay was used to observe the effect of scavenging hydroxyl radical from H_2O_2/Fe 2+ system by the aquenous extracts of Cordyceps. Results Cordyceps from Naqu of Xizang,northwest Yunnan,and northwest Sichuan all showed us the significant effect on scavenging of hydroxyl radical produced from Fenton Reaction. The biggest values of MDR among Cordyceps specimens from various microecological environment surpassed that among specimens of Naqu of Xizang,northwest Yunnan,and northwest of Sichuan. Conclusion The aquenous extracts of Cordyceps could scavenge the hydroxyl radical from Fenton Reaction. The microecological environment for Cordyceps growing has an significant effect on its scavenging action.
