Eine neue Methode zum Abbau von Anthocyanidinen, Flavonen, Chalkonen und Cumarinen
A New Method for the Degradation of Anthocyanidins, Flavones, Chalcones, and Coumarins 
 
 
 
After transformation into the corresponding chalcone or flavenol acetates anthocyanidins are oxidatively cleaved with ruthenium tetroxide to yield benzoic acid derivatives of the rings A and B. Flavones, chalcones, and coumarins are degradated by the same method.
