Evaluation of General Synthesis Procedures for Bioflavonoid-Metal Complexes in Air-Saturated Alkaline Solutions.

The general synthesis methods of bioflavonoid-metal complexes are considered to be unreliable due to the instability of flavonoids in air-saturated alkaline solutions. In this study, dihydromyricetin (DHM), as a representative bioflavonoid, was selected for complexation with various transition metal ions in an air-saturated alkaline solution to form DHM-metal(II) complexes, following the general synthetic procedure. After characterization, the metal complexes were hydrolyzed to observe the stability of DHM under acidic conditions via HPLC.
