Piceid Explained

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).

Resveratrol can be produced from piceid via the mold Aspergillus oryzae.^[3] as the fungus produces a potent beta-glucosidase.^[4]

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.^[5]

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