S-adenosyl-L-methionine + a flavonoid 4’-OMT methylates the position 4’ in the B-ring of flavonoids, uses flavonoids methylated in the 3’-position of the B-ring to synthesize a 3’,4’-methylated product, a methylated flavanone, homoeriodictyol, is the best substrate Catharanthus roseus S-adenosyl-L-homocysteine + a 4'-methoxyflavonoid
