Extraction and in vitro antioxidant activity of intracellular polysaccharide by Pholiota adiposa SX-02.

Response surface methodology (RSM) was used to optimize the extraction parameters for Pholiota adiposa SX-02 intracellular polysaccharide (IPS) produced during submerged culture. The optimum conditions of IPS extraction were predicted to be, ultrasonic power at 564.93 W, precipitation time 30.
