Abstract:
Mushrooms are widely used in therapeutics, due to their various biological effects. The aim of our paper was the assessment
of the chemical composition and the assessment of the antioxidant activity of Agaricus bisporus (wild-growing and
cultivated) and Agaricus blazei (cultivated) mushrooms. Phytochemical screening was determined by means of
spectrophotometric, spectrometric, and X-ray diffraction methods. Antioxidant activity was assessed by scavenger activity
towards DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS·+ (2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) free radicals,
ferric reducing power and ferrous ions chelating properties. Wild-growing Agaricus bisporus and Agaricus blazei have a
similar total phenolic content. The highest calcium (1783.14 mg/kg), potassium (99580.08 mg/kg) and magnesium (1070.79
mg/kg) concentrations were found for wild-growing Agaricus bisporus. Cultivated Agaricus bisporus had a weak antioxidant
capacity. All analysed mushrooms are a source of bioactive compounds with antioxidant activity.
