What is Polydatin?
Polydatin powder, also known as Piceid, is a glucoside of resveratrol powder in which glucose is transferred to the C-3 hydroxyl group.
Polydatin has two isomeric forms that exist in nature, cis-polydatin, and trans-polydatin.
It is a well-known stilbene compound with healthy biological activity and a terpenoid compound.
Usually, 98% of natural polydatin is derived from an Asian origin herb Polygonum Cuspidatum Sieb. Et Zucc appeared with white powder as one of the main active ingredients.
Food Sources of Polydatin
Polydatin is widely distributed in plants; the most abundant source is Polygonum Cuspitadum. Also, you can find it in grape, peanut, hop cones, red wines, hop pellets, cocoa-containing products, chocolate products, and many daily diets.
Grape
Polydatin was first reported in the peel of grapes. Grape skins exhibit higher polydatin contents than the seeds (Kammerer et al. 2004).
In red grape juices, trans-polydatin’s average concentration is 3.38 mg/L,cis-polydatin is 0.79 mg/L; In white grape juices, trans-polydatin is 0.18 mg/L, cis-polydatin is 0.26 mg/L.
Peanut
contents in natural peanut butter were found to be significantly higher than those in blended peanut butter.
Red wines
Red wine contains up to 14.3 mg/l, and 29.2 mg/l of trans-resveratrol and polydatin.
Cocoa and chocolate
Polydatin detected in cocoa and chocolate products is about 3-5 times more than Resveratrol.
| Name | Content |
| cocoa powders | 7.14 LG/g |
| unsweetened baking chocolates | 4.04 LG/g |
| semisweet chocolate baking Chips | 2.01 LG/g |
| dark chocolates | 1.80 LG/g |
| milk chocolates | 0.44 LG/g |
| chocolate syrups | 0.35 LG/g |
Polydatin is Resveratrol?
The answer is NO.
Resveratrol, also known as 3,4′,5-Trihydroxy-Trans-stilbene, is a stilbenoid, a type of natural phenol famous for chemopreventive, antidiabetic, and neuroprotective properties.
Polydatin is a biological precursor of resveratrol, resveratrol’s glucoside form. The related brand is PTEROMAX™ by Biotivoia.

Flowchart for Polydatin Extraction
The dried Polygonum cuspidatum root is pulverized, extracted with ethanol as the solvent, concentrated, crystallized, dried, smashed, obtained the crude polydatin, then packaged and put into the warehouse after testing.
