Uniquely identifiable characteristics
Distinguishing Feature :
A very vigorous ornamental grape which can climb up to 20m on walls and other vertical surfaces. It has non-poisonous but barely edible blackish-blue berries. This fruit is about 12mm in diameter and is a blackish-blue with a matte whitish sheen which rubs off. The spectacular heart-shaped leaves turn stunning shades of gold, orange and then crimson in Autumn and are remarkably up to 30cm long.
The tiny inconspicuous flowers appear in summer, have 5 petals and are green.
ε-Viniferin is a
Stilbenoid and a dimer of Resveratrol, a
polyphenol, although that is not immediately apparent from the layout of the two Resveratrol moieties, so your Author has thoughtfully coloured the two Resveratrols red and cyan. The two black lines are just molecular bonds connecting the two Resveratrols, they are not extra atoms, although ε-Viniferin has lost two hydrogen atoms from the two combined Resveratrols. The observant amongst the readers will notice that a
Furan ring has formed as part of the dimer which is common to both Resveratrol moieties. Resveratrol is not listed as one of the compounds present in this plant, but it is a fairly common secondary metabolite.
ε-Viniferin is also found in in other vines, such as
Grape-Vine (Vitis vinifera)
Crimson and in the bark of the non-native
Camphor Tree (Dryobalanops aromatica) which also accommodates the
C-glycoside of ε-Viniferin called
Rhapontigenin, also found in Crimson-Glory-Vine and in a liana from South East Yunan, is the methoxy version of Resveratrol. It exhibits anti-cancerous properties against prostrate Cancer by inhibiting
Cytochrome P450 1A1, and enzyme present in the human body.
