Three new neoflavonoids, named (1,8,9)-1,5-dihydroxy-4,12-dimethoxy-8-vinyl-tricyclo[7.3.1.0]trideca-2,4,6,11-tetraen-10-one (), 2,5,2',5'-tetrahydroxy-4-methoxybenzophenone () and 2,5,3'-trihydroxy-4-methoxybenzophenone (), were isolated from the heartwood of Their structures were established by spectroscopic methods, including UV, IR, HRMS, 1 D and 2 D-NMR. Compounds - were evaluated for inhibitory activity against three fungal strains , , and seven bacterial strains , , , , , , using the broth dilution method. However, none of compounds showed potential antimicrobial activities .
