Bioactivity of Edible Mushrooms

Here we evaluated antioxidant and antimicrobial activity of the acetone and methanol extracts of the mushrooms Amanita rubescens and Russula cyanoxantha. Antioxidant activity was evaluated by free radical scavenging, reducing power activity and determination of phenolic content. As a result of the study acetone extracts from Russula cyanoxantha was more powerful antioxidant activities (IC50 = 86.279 µg/ml). Moreover, the tested extracts had effective reducing power. Total content of phenol in extracts was determined spectrophotometrically. The antimicrobial activity was estimated by determination of the minimal inhibitory concentration by using microdilution plate method. Generally, the tested mushroom extracts had relatively strong antimicrobial activity against the tested microorganisms
