The reactivity of the various antioxidants was compared to the
reactivity of Trolox, a water-soluble vitamin E analogue. The relative
radical scavenging capacity of fungal extracts in terms of their
EC50 values are displayed in Table 2. In agreement with the data
obtained following the b-carotene assay, the extraction process
was an extremely important factor in the isolation of antioxidant
compounds. The methanol extracts generally demonstrated the
greatest activity proceeded by the hot water and crude extracts.
