In the present study, fruits extracts (Paullinia cupana K. & Libidibia ferrea M. - guarana & juca, respectively) of the Amazon Region were tested for antifungal and antimycotoxigenic activities against Aspergillus parasiticus using the agar dilution method. The treatments utilized were at three different concentrations (1.08, 1.62 and 3.24%). The effect on both extracts on growth diameter of fungal colony was time and concentration dependent. No treatment completely inhibited fungi growth, however A. parasiticus was significantly reduced by the treatments when compared to the control group. The production of AFB1, AFB2, AFG1 and AFG2 by A. parasiticus grown on guarana and juca extracts treatment was significantly smaller when compared to controls. A. parasiticus strain produced aflatoxins in all concentrations when grown on guarana extracts medium treated and different of that observed when on juca’s treated extracts.
