Sensitive Spectrophotometric Assay for 3-Hydroxy-Substituted Flavonoids, Based on Their Binding with Molybdenum, Antimony, or Bismuth

A sensitive spectrophotometric assay has been developed for flavonoids based on their binding with molybdenum, antimony, or bismuth. Acetylation of the hydroxyl group of flavonoids abolished metal binding, thus suggesting a direct role of the hydroxyl groups. From a comparison of several related fla...
