Teak ( Tectona grandis L.f., Verbenaceae) sawdust extract inhibited the growth of Aspergillus niger. Centrifugal partition chromatography was used to isolate the active compounds. By (1)H-NMR the active compounds were identified as deoxylapachol and tectoquinone. Two A. niger transgenic strains which show induction of 1,3 -alpha-D-glucan synthase were used as a cell wall damage model. The result showed that deoxylapachol from T. grandis extract induced fungal cell wall stress.
