Piceid is a stilbenoid glucoside and is a major resveratrol derivative in grape juices. [1] It can be found in the bark of the Sitka spruce (Picea sitchensis), hence its name. [2] It can also be isolated from Japanese knotweed (Reynoutria japonica). [3]

Polydatin, or Piceid, is a natural precursor and glycoside form of resveratrol with a monocrystalline structure. While it is isolated from the bark of *Picea sitchensis* or *Polygonum cuspidatum*, polydatin may be detected in grape, peanut, hop cones, red wines, hop pellets, cocoa-containing products, chocolate products and many daily diets.

Polydatin (Piceid), extracted from the roots of Reynoutria japonica, a widely used traditional Chinese remedies, possesses anti-inflammatory activity in several experimental models. Polydatin (Piceid) inhibits G6PD and induces oxidative and ER stresses. Polydatin 通过改善微循环和抑制血小板聚集来保护脑细胞免受缺血性损伤。

Piceid, a precursor of resveratrol, is the most abundant form of resveratrol in nature. A number of studies have hypothesized that piceid may have the same bioactivities like those of resveratrol. The aim of this work is to compare piceid with resveratrol in antioxidation and antiproliferation activities in vitro.
