✦ Synopsis

An inhibitor of Aspergillus flavus has been isolated form peanuts and identified as 5,7-dimethoxyisoflavone, Authentic 5,7-dimethoxyisoflavone, synthesized from benzyl-2-hydroxy-4,6 dimethoxyphenyl (3), and the isolated compound display identical ultraviolet spectra in methanol, in methanol+sodium methoxide, and in methanol+AlCl3; similar behavior in solvent extraction, column chromatography, TLC, and fungal inhibition.
