Шаблон:Chembox δ-Viniferin is a resveratrol dehydrodimer. It is an isomer of epsilon-viniferin. It can be isolated from stressed grapevine (Vitis vinifera) leaves.[1] It is also found in plant cell cultures[2] and wine.[3] It can also be found in Rheum maximowiczii.[4]

It is a grapevine phytoalexin following stresses[1] like fungal infection (by Plasmopara viticola, the agent of downy mildew),[5] UV light irradiation or ozone treatment.[6]

Botryosphaeria obtusa, a pathogen responsible for the black dead arm disease of grapevine, has also been shown to be able to oxidise wood δ-resveratrol into delta-viniferin.[7]

In cell cultures, the use of methyl jasmonate and jasmonic acid as elicitors stimulates δ-viniferin biosynthesis.[8]

Delta-viniferin can also be produced from resveratrol by human PTGS1 (COX-1, cyclooxygenase-1)[9] or from trans-resveratrol and (−)-epsilon-viniferin by horseradish peroxidase.[10]
