Fig. 5From: Biochemical characterization of a regiospecific flavonoid 3'-O-methyltransferase from orangeHPLC analysis of the CsOMT16 reactions with flavonoid substrates. The upper panels are HPLC chromatograms of the CsOMT16 reaction mixtures with eriodictyol (a), luteolin (b), and quercetin (c). Lower panels are chromatograms of authentic 3'-methoxyflavonoids, homoeriodictyol, chrysoeriol, and isorhamnetin. S substrate, P reaction productBack to article page
