Polydatin, or piceid is a stilbenoid glucoside and is a major resveratrol derivative in grape juices. It can be found in the bark of Picea sitchensis. It can also be isolated from Fallopia japonica, the Japanese knotweed (syn. Polygonum cuspidatum).

Resveratrol can be produced from piceid fermented by Aspergillus oryzae. This latter species produces a piceid-b-D-glucosidase.

Trans-piceid is the glucoside formed with trans-resveratrol, while cis-piceid is formed with cis-resveratrol.

Trans-resveratrol-3-O-glucuronide is one of the two metabolites of trans-piceid in rat.

Resveratrol glucoside from transgenic alfalfa has been used for the prevention of aberrant crypt foci in mice.
