A current scientific challenge is to describe the activity of the characteristic endogenous components and some physiologically important enzymes of cultivated mushroom species/varieties. The well-known beneficial effects of Agaricus bisporus are due to its components of reductive capacity and its enzymatic defense against stress. During our research we investigated and characterized the reductive capacity of Agaricus bisporus mushroom cultivars, and defined the enzymatic activity (peroxidase, polyphenol oxidase) contributing to the antioxidant defense and that of the total polyphenol content known from non-enzymatic defense by using a method based on ferric reductive capacity (FRAP). Based on the investigated characteristics our aim was to compare the quantity of bioactive endogenous components of Agaricus bisporus mushroom varieties and thus select the best cultivars. As a result of our research a significant difference was detected among the different varieties concerning their endogenous component with reductive capacity. Through analysis of the connections, the cultivars with the best characteristics were selected.
