Infobox references

α-Viniferin is a stilbene trimer. It can be isolated from Caragana chamlagu^[1] and from Caragana sinica^[2] and from the stem bark of Dryobalanops aromatica.^[3] It is also present in relation to resistance to Botrytis cinerea and Plasmopara viticola in Vitis vinifera and Vitis riparia.^[4]

It has been shown to inhibit acetylcholinesterase.^[1]
