Negative values represent the % of ROS reduction, positive values should be considered as lack of radical scavenging. P < 0.05 (*), P < 0.001 (**), P < 0.0001 (***) significance compared to control. Results are shown as mean ± SD of three independent experiments

The % of DPPH^• radical reduced by CM-α-(1→3)-d-glucan from macromycetes fungi is compared to the control (0% of reduction)^a
