Abstract: | Plant-cultured cells of Catharanthus roseus converted trans-resveratrol into its 3-O-β-D-glucopyranoside, 4'-O-β-D-glucopyranoside, 3-O-(6-O-β-D-xylopyranosyl)-β-D-glucopyranoside, 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 4'-O-β-D-glucopyranoside. |
