 Title    Oxidation of Flavanones to Flavones with Flower Extracts of Antirrhinum majus (Snapdragon)  
 Abstract    Enzyme preparations from flowers of Antirrhinum majus catalysed the oxidation of naringenin to apigenin and o f eriodictyol to luteolin. Enzyme activity was found to be localized in the microsomal fraction. The reaction required NADPH as cofactor and had a pH optimum o f about 7.0. The NADPH-dependent microsomal enzyme activity was also present in flower extracts of other flavone-producing plants, whereas flower extracts of plants which lack flavones were found to lack also this enzyme activity.
