 Title    Stepw ise M ethylation of Quercetin by Cell-Free Extracts of Citrus Tissues  
 Abstract    The cell-free extracts of peel, root, or callus tissues of citrus catalyzed the stepwise O-methylation of quercetin to rham netin, isorham netin and rhamnazin. Both rham netin and isorham netin were further m ethylated to rhamnazin and possibly to a trim ethyl ether derivative of quercetin. The results seem to indicate the existence of both m eta and para directing enzymes that are involved in the biosynthesis of m ethylated flavonoids in citrus tissues.
