Sinningia cardinalis

An enzyme from the flowers of Sinningia cardinalis Reichsteinia cardinalis, Gesneriaceae) has hydrolase activity associated with microsomal fractions and requires NADPH as an essential cofactor (hydrolyase activity II). This enzyme converts naringenin (10) and apigenin (5) to eriodictyol (17) and luteolin (4), respectively (Dewick, 1989). The flavone synthase activity of this enzyme was abolished completely by treatment with the cytochrome P-450 inhibitor ancymidol, but the flavonoid 3 -monooxygen-ase activity was not altered. [Pg.160]
