Fungal endophytes are a significant reservoir of novel bioactive secondary metabolites. Present communication describes isolation and structure determination of isochromenone, from endophytic microorganism Aspergillus fumigatus hosted in Bacopa monnieri plant. Further, its biological evaluation revealed it as antioxidant and antitubercular. The methanol extract of A . fumigatus inhibits the growth of the virulent strain of Mycobacterium tuberculosis H37RV with minimum inhibitory concentration 500 μg/mL. This is the first report of isolation of isochromenone from A. fumigatus.
