Determination of Chemical Antioxidants and Phenolic Compounds in the Brazilian Mushroom Agaricus sylvaticus

摘要

Agaricus sylvaticus mushroom has been widely studied because of its high nutritional value and medicinal properties. The objective of this study was to evaluate the antioxidant potential of both alcoholic and aqueous extracts of Agaricus sylvaticus and quantify their total polyphenol content. The antioxidant activity was performed by the 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity and total polyphenol content was assessed by colorimetric method. Observation also noted the great antioxidant potential of aqueous, alcoholic and ethereal extracts (14.6%, 75.6% and 14.6%, respectively) of the Agaricus sylvaticus mushroom, highlighting the alcoholic extract, which demonstrates the extraordinary benefits of this mushroom in the diet, since antioxidants prevent premature ageing and various types of cancer.
