Abstract:In order to investigate the optimal extraction of Auricularia auricula.Based on the anthocyanin extraction rate，extracting reagent，operating time，operating temperature，and the ratio of material to solution were studied.Orthogonal experiments were designed base on singly factor experiments to obtain the optimum extraction process.Macroporous resin was used to purify the crude extracts.The extracts were evaluated for their antioxidant activity and antioxidant activity.The results showed that the optimal conditions of anthocyanin extracts were as follows：solid-liquid ratio 20 ∶1（mL/g），incubation temperature 60 ℃，incubation time 60 min，and acidify ethanol as extractants.Further，the antioxidant capacity was significantly higher than the same concentration of ascorbic acid.And the anthocyanin extracts had significant inhibition effect on the growth of Escherichia coli and Staphylococcus aureus.
