Using 50% ethanol and supercritical carbon dioxide different mushroom extracts were prepared. After analysis of extraction yield, content of total phenols and total flavonoids, content of macro-elements and micro-elements, as well as content of adenosine and characteristic compounds (pistilarin and variegetic acid) were determined. Highest content of total phenols was determined in C. pistillaris extract, highest content of total flavonoids in D. confragosa and highest content of essential zinc and selinum in B. edulis dry extract. In comparison to other extacts L. saccatum posses few time higher content of adenosine. Antioxidant activity was analyzed by spectrophotometric and EPR methods. Extracts of C. pistillaris, B. edulis and A. mellea have been showed as a most efficient in scavenging of dangerous OH radical. In lipid peroxidation prevention significant were mushrooms extract of B. edulis, A. mellea and L. saccatum. After determination of mushrooms supercritical extraction yield, fatty acid composition and sterol components were analyzed. Dominant unsaturated fatty acid in investigated mushrooms extracts was linoleic acid. Content of oleic fatty acid was also significant. Dominant compound of sterol structure, in almost all supercritical extracts, was ergosterole. Influence of supercritical mushroom extracts on erythrocyte membrane fluidity was investigated. According to obtained results, mushrooms A. mellea and M. procera could have significant role in antihypertensive diet.
