摘要：

In this study, 19 endophytic fungi were isolated from Lafoensia pacari, Guazuma ulmifolia, Campomanesia xanthocarpa and Siparuna guianensis. Seventeen strains were molecularly identified as belonging to the genera Colletotrichum, Diaporthe, Bjerkandera, Talaromyces, Cochliobolus, Phaeophlebiopsis, Curvularia, and Xylaraceae. Assays for detecting antioxidant activity were performed by free radical scavenging activity using the DDPH and ABTS + methods. Based on the results with DPPH, two strains were selected to evaluate the presence of flavonoids and anti-inflammatory activity. A strong positive correlation was found between these activities and the presence of flavonoids. The anti-inflammatory activity of endophytic fungi is under explored; however, the Talaromyces obtained the best result of 87.33% protection of erythrocytes and Colletotrichium of 60.71%. This study demonstrated that endophytic fungi associated with selected plants are potential sources of novel antioxidant products.
