Soluble polyphenols: synthesis and bioavailability of 3,4',5-tri(alpha-D-glucose-3-O-succinyl) resveratrol.

We report the development of a chemical modification method of general applicability to polyphenols, which increases solubility to influence absorption. Glucosyl groups were added to the resveratrol kernel via a succinate linker, yielding 3,4',5-tri-(alpha-D-glucose-3-O-succinyl) resveratrol. The construct was only slowly hydrolyzed in acid and at pH 6.
