  <name>7,4'-Dimethoxyflavone</name>
  <description>7,4'-dimethoxyflavone is a member of the class of compounds known as 7-o-methylated flavonoids. 7-o-methylated flavonoids are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. 7,4'-dimethoxyflavone is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 7,4'-dimethoxyflavone can be found in fenugreek, which makes 7,4'-dimethoxyflavone a potential biomarker for the consumption of this food product. </description>
