Abstract:Auricularia auricula from Yunnan， Fujian and Heilongjiang were extracted for polyphenols and their antioxidant activities were compared. The results showed that the reducing capacity， scavenging ability of DPPH·（IC50=4.12 mg/L） and scavenging capacity of O2-·（IC50=15.17 mg/L）， polyphenol crude extracts from the Heilongjiang's Auricularia auricular were the strongest. Yunnan Auricularia auricula polyphenols extract in the scavenging capacity of hydroxyl radical （IC50=302.52 mg/L） and lipid peroxidation （IC50=23.67 mg/L） are the strongest. In general， the antioxidant activity of Auricularia auricula from Heilongjiang and Yunnan was higher than that of Fujian black fungus， which may be related to the content of polyphenols in different regions.
