In order to explore the antioxidant ability of different solvent extracts of Ge-riched Auricularia auricular mycelium in vitro, the Ge-riched A. auricular mycelium was extracted by water, 70% ethanol and ethyl acetate. The scavenging ability of different extracts on superoxide anion free radical, hydroxyl free radical and DPPH free radical were compared. The comprehensive antioxidant capacity of different solvent extracts was evaluated by subordinate function value, and the correlation between substance content and antioxidant capacity were analyzed. The results showed that the content of organic Ge in Ge-riched A. auricular mycelium was 542.83 μg/g. The extraction rate and substance content of different solvent extracts were different, the extraction rate of water extract and ethanol extract was higher, the polysaccharide content of water extract was the highest, and the polyphenol and flavonoid content of ethyl acetate extract was the highest. Different solvent extracts had certain scavenging ability on free radicals,and the extract concentration increased with the increase. Water extract had the strongest scavenging rate of superoxide anion free radical,when the extract concentration was 9 mg/mL, the highest clearance rate was 43.32%. 70% ethanol extract had the best scavenging effect on hydroxyl free radical and DPPH free radical. When the extract concentration was 9 mg/mL, the scavenging rate was 70.10% and 76.99%, respectively. Polysaccharides, polyphenols and flavonoids all played different roles in scavenging free radicals, and ethanol extract had the strongest comprehensive antioxidant capacity. The contents of polysaccharides, polyphenols and flavonoids were significant (P
