  1. Note:
  2. aReducing power was determined using the ferric reducing antioxidant power (FRAP) assay (μmol·L−1). Expressed as μM Fe(II)/mL filtrate, each value was the mean ± SD (n = 3).
  3. bEach value was the mean ± SD (n = 3).
  4. cSum of the degree of membership in YFRAP and YDPPH.
  5. Fungi selected by antioxidant screening.
