Previous studies have shown that PD exhibits many pharmacological activities, including cardioprotective, neuroprotective, and antioxidative activities.

Polydatin, a type of polyphenolic phytoalexin, has many physiological and pharmacological effects including anti-inflammatory and anti-oxidative activities. Polydatin is an effective candidate drug for the protection of photo-inflammation. Polydatin exhibits therapeutic potential for vascular dementia, most likely due to its anti-oxidant activity and the direct protection of neurons.

Trans-piceid is a stilbenoid that is trans-resveratrol substituted at position 3 by a beta-D-glucosyl residue. It has a role as a metabolite, a potassium channel modulator, an anti-arrhythmia drug, a hepatoprotective agent, an antioxidant and a nephroprotective agent. It is a stilbenoid, a polyphenol, a beta-D-glucoside and a monosaccharide derivative. It derives from a trans-resveratrol.
