Agaricus impudicus Coprinus comatus Hydnum repandum Sarcodon imbricatus Antioxidant activity
Many researchers agree that edible mushrooms have beneficial effects on human health. The aim of this study is to investigate the chemical composition and antioxidant activities of methanol extracts obtained from Coprinus comatus, Hydnum repandum, Agaricus impudicus ve Sarcodon imbricatus collected from Yuvacık-İzmit, Kastamonu, and Uzungöl-Trabzon. Spectrophotometric analysis showed that the total phenolic (64.69 mg GAEs/g) and flavonoid (1.73 mg QEs/g) content of S. imbricatus was higher than that of the others. In line with its superiority in phytochemical composition analyzes, S. imbricatus extract showed the highest activity in -carotene bleaching, DPPH free radical scavenging and reducing power assays (836.0, 89.0 and 267.0 mg TEs/g extract, respectively). Metal chelating test resulted in the superiority of A. impudicus (1282.0 mg TEs/g). Relative antioxidant capacity index (RACI) value of S. imbricatus was quite high compared to other extracts (0.90). Apart from the metal chelating assay, there was a high correlation between the antioxidant activities of the extracts and their RACI values. Pearson correlation analysis showed that the correlation between the phenolic/flavonoid contents of the extracts and their antioxidant activities was over 0.9. The antioxidant activity of A. impudicus was brought to the literature for the first time with this study. When the data obtained from the current study were evaluated as a whole, it was concluded that S. imbricatus could be a rich source for new and alternative antioxidant compounds.
