Pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene) is a stilbene compound that is structurally similar to other popular stilbenes such as Resveratrol or Piceatannol; it is named after its first discovered source (the pterocarpus genus) but is also a component of blueberries and grape products. It is a phytoalexin (compound produced by plants as a defense against parasites and insects) similar to resveratrol albeit more potent.Pterostilbene is contained in low quantities in a few plants,like Pterocarpus marsupium(Indian kino tree),Pterocarpus santalinus(sandalwood),Blueberries,Grape leaves and Berries.The structure of pterostilbene is very similar to resveratrol, although the 3,5-dihydroxy part of resveratrol (the two hydroxyl groups on the benzene ring to the left) are replaced with methoxy groups.

Artificial Synthesis

Pterostilbene is a chemical constituents contained in red sandalwood, but scientists in other plants have also found a pterostilbene, but because it's the first found with rosewood species, solid named pterostilbene.Recently, researchers has mastered the industrial synthesis method of pterostilbene

To 3,5 - dimethoxy benzyl bromide and p-nitrobenzaldehyde as raw material, the witting hornor reaction, reduction, diazotization, which can be hydrolyzed to the object, with 53.9% overall yield synthesized natural multifunctional antioxidant pterostilbene, and the structure of the target by IR, 1H NMR and ei-ms. were characterized. The synthesis process is simple, operation is convenient, the production cost is low, has good prospects for industrial applications
