The Box-Behnken experimental results showed the optimum extraction conditions as follows: a liquid-solid ratio of 38.77 mL-g, a temperature of 93.98 °C and a time of 3.41 h.
Under these conditions, the maximal polysaccharide yield was 10.46 g-100 g.
In addition, AAFB polysaccharides exhibited stronger antioxidant activities by evaluating of Fe2 -chelating ability and hydroxyl radical scavenging activity with IC50 values of 0.43 and 0.38 mg-mL, respectively.
These results indicated that AAFB polysaccharides might be potentially used as a natural antioxidant. Keywords: Auricularia auricula; polysaccharide; extraction; antioxidant activity. Practical Application: A.
