Antioxidant properties of extracts from cultured and wild macromycetes

The antioxidant properties of benzene, methanol, and ethanol extracts from Agaricus bisporus, Lentinula edodes, Pleurotus ostreatus (cultivated species); Fomes fomentarius, Inonotus obliquus и Trametes versicolor (wild species) were studied. The total content of flavonoids and antioxidant activity were evaluated (DPPH, PFRAP, CUPRAC and β-carotene bleaching assay). The yield of benzene extracts was up to 1.9%; methanol up to 7.2%; ethanol to 9.6%. The content of total flavonoids in methanol and ethanol extracts from wild macromycetes was up to 29.5 mEq of rutin per gram of extract. Extracts from macromycetes showed low antioxidant activity in the PFRAP and CUPRAC reactions. It was found that methanol extracts from F. fomentarius and T. versicolor , as well as ethanol extracts from L. edodes , F. fomentarius and T. versicolor , have high antiradical activity against DPPH and β-carotene radical.
