Piceid is a stilbenoid glucoside and is a major resveratrol derivative in grape juices.^[1] It can be found in the bark of Picea sitchensis.^[2] It can also be isolated from Reynoutria japonica (syn. Fallopia japonica),^[3] the Japanese knotweed (syn. Polygonum cuspidatum).

trans-Resveratrol-3-O-glucuronide is one of the two metabolites of trans-piceid in rat.^[5]

Resveratrol glucoside from transgenic alfalfa prevents aberrant crypt foci in mice.^[6]
