δ-Viniferin is a resveratrol dehydro dimer. It is an isomer of epsilon-viniferin. It can be isolated from stressed grapevine ( Vitis vinifera) leaves. [3] It is also found in plant cell cultures [4] and wine. [5] It can also be found in Rheum maximowiczii. [1]
It is a grapevine phytoalexin following stresses [3] like fungal infection (by Plasmopara viticola, the agent of downy mildew), [6] UV light irradiation or ozone treatment. [7]
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. [8]
In cell cultures, the use of methyl jasmonate and jasmonic acid as elicitors stimulates δ-viniferin biosynthesis. [9]
Delta-viniferin can also be produced from resveratrol by human PTGS1 (COX-1, cyclooxygenase-1) [10] or from trans-resveratrol and (−)- epsilon-viniferin by horseradish peroxidase. [11]
