Glycosylation of trans-resveratrol by plant-cultured cells

Abstract

Plant-cultured cells of Catharanthus roseus converted trans-resveratrol into its 3-O-β-D-glucopyranoside, 40-O-β-D-glucopyranoside, 3-O-(6-O-β-D-xylopyranosyl)-β-Dglucopyranoside, and 3-O-(6-O-α-L-arabinopyranosyl)-β- D-glucopyranoside. The 3-O-(6-O-β-D-xylopyranosyl)-β-D-glucopyranoside and 3-O-(6-O-α-L-arabinopyranosyl)-β-D-glucopyranoside compounds of trans-resveratrol are both new. Incubation of plant-cultured cells of Ipomoea batatas and Strophanthus gratus with trans-resveratrol gave trans-resveratrol 3-O-β-D-glucopyranoside and trans-resveratrol 40-O-β-D- glucopyranoside.
