Abstract:In this paper ,the Flammulina velutipes is cultured by means of enriching germanium and the quantity of the germanium is 600 μ g/mL. After getting the mycelium,we use three kinds of solvent to extract the mycelium in different conditions,such as water, 75% ethanol and 70% ethyl and we studyed the antioxidant capacity of the extractions.The paper reserched the scavenging capacity of different solvent extracts of ge-rich golden mushroom mycelia about oxygen free radical, hydroxyl radical and superoxide anion free radical, and after comparing we found the capacity of the germanium-enriched extractions is better than those who was not added the germanium. At the same time, the scavenging capacity of water extract is the best on oxygen free radical and reach to 88%. The restraining capacity of of 75% ethanol is the best on hydroxyl radical, which can reach to 800.3U/g .The scavenging capacity of water extract is the best on superoxide anion free radical and the enzyme which can reach to 195.9U/g.
