ε-Viniferin is a naturally occurring phenol, belonging to the stilbenoids family. It is a resveratrol dimer.

It is found in Vitis vinifera[4] grapevines,[5] in wines,[6] in the Oriental medicinal plant Vitis coignetiae and in the stem bark of Dryobalanops aromatica.[7]
Cis-epsilon-viniferin can be found in Paeonia lactiflora.[3]

It shows a human cytochrome P450 enzymes inhibition activity.[8]

Glycosides

Diptoindonesin A is a C-glucoside of ε-viniferin.
