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]
