SSGL = sporoderm-broken spores of Ganoderma lucidum; T-AOC = total antioxidant capability; CAT = catalase; T-SOD = total superoxide dismutase; GR = glutathione reductase; GSH-Px = glutathione peroxidase; GSH = reduced glutathione.

^{a, b, c}Means with different superscripts within the same row are different (P < 0.05).

¹Each value represents the mean of 5 replicate values.
