Biotransformation of the daidzein ditiglate (2) by fungi, Aspergillus niger and Glomerella cingulata was investigated. Compound 2 was transformed to daidzein (1) by A. niger and G. cingulata. This suggested that compound 2 was converted to compound 1 by hydrolysis at both of the C-7 and C-4' positions.
