ABSTRACT
Different maturation phases of basidiocarp could affect the bioactivity and concentration of some active substances. A. brasiliensis Wasser et al.(A. blazei Murrill) has shown antitumor activity that could be related to the antioxidant activity. However there is no information of the best basidiocarp maturation phase for extracting antioxidant substances in order to determine the moment of harvesting in mushroom cultivation. The objective of this work was to evaluate the antioxidant activity of A. brasiliensis strains on different basidiocarp maturation phases. The best condition for extraction of A. brasiliensis antioxidants is with methanol as solvent at 60 ºC for 60 min. Strains with closed basidiocarp have higher antioxidant activity than with opened basidiocarp. Antioxidant activity varies in each strain. It was concluded that A. brasiliensis is a natural source of antioxidant compounds. Also there is higher antioxidant activity in closed than opened caps and consequently higher functional activity. It reinforces the synergic action among different A. brasiliensis compounds as a functional food and the importance of further investigation for isolation and characterization of antioxidant substances of A. brasiliensis. It also determines the best harvest period in order to obtain the highest antioxidant activity from basidiocarp.
