Glycosylation and Malonylation of Quercetin, Epicatechin, and Catechin by Cultured Plant Cells

Quercetin was converted to quercetin 3-O-(6-O-malonyl)-β-D-glucoside through the regioselective glucosylation at 3-position of quercetin and the following regioselective malonylation at 6-position of sugar moiety of quercetin 3-O-β-D-glucoside with cultured Nicotiana tabacum cells. On the other hand...

Description
Summary:Quercetin was converted to quercetin 3-O-(6-O-malonyl)-β-D-glucoside through the regioselective glucosylation at 3-position of quercetin and the following regioselective malonylation at 6-position of sugar moiety of quercetin 3-O-β-D-glucoside with cultured Nicotiana tabacum cells. On the other hand, N. tabacum cells glucosylated epicatechin and catechin to the corresponding 3′-, 5-, and 7-O-β-D-glucosides, respectively.
