Antioxidant status maintenance plays a significant role for mushroom cultures in respect to oxidative stress resistance, cytodifferentiation and transition to the generative stage. Strong antioxidants are the selenium compounds. One of the antioxidant action indices is the antiradical activity determined by means of the spectrophotometric method using the reactions with the free radical 1,1-diphenyl-2-picrylhydrazyl (2,2-diphenyl-1-picrylhydrazyl, N,N-diphenyl-N’-picrylhydrazyl, DPPH) (C6H5) 2N– N•–C6H2(NO2) 3-2,4,6.
