This study aims at defining the antioxidative activities of extracts of Daedaleopsis tricolor wild and cultivated basidiocarps and mycelium and assessing their dependance on substrate type. Ethanol extracts (at a concentrations from 0.25 mg/mL to 16.00 mg/mL) of mycelium and wild fruiting bodies showed a considerable antioxidative potential (88.65% and 81.57%, respectively), which was almost the same as the commercial antioxidant BHA (88.91%). These radical scavenging abilities were reflected in EC50 values, which were 12.45 mg/mL for the extract of cultivated basidiocarps, 8.29 mg/mL for the extract of wild basidiocarps, 7.93 mg/mL for mycelium one, and 0.10 mg/mL for commercial antioxidant. Despite the fact that phenol proportion in the extracts was no negligible (between 20.41 μg GAE/mg of the extract of dry wild basidiocarps and 146.37 μg GAE/mg of the extract of dry cultivated basidiocarps), its correlation with antioxidative activity was moderate. Flavonoids, in significant concentration, were detected only in the extract of cultivated fruiting bodies (28.64 μg QE/mg of dry extract), but no correlation with radical scavenging capacity was noted. A remarkable antioxidant potential, especially of the submerged cultivated mycelium, put D. tricolor high on the list of promising new natural antioxidants. |
