Antioxidant and Immunomodulatory Activities of Polysaccharides from Fermented Wheat Products of Grifola frondosa: In Vitro Methods

Figure 2

DPPH radical scavenging relative activity of different polysaccharide samples from G. frondosa, wheat, and their SSF (solid-state fermentation) products. Samples were run in triplicate, and the results from one representative experiment are shown (). The relative activity of DPPH radical scavenging is shown on the -axis, and the different samples are labeled on the -axis. Vitamin C was used as a positive control, with its relative activity set at 100%. The figure could help to compare the antioxidant activity of the different samples and evaluate the effectiveness of SSF in enhancing their antioxidant properties.
