Red Vine Leaf Extract

Red vine leaf extract is a substance of unknown or variable composition, complex reaction products, or biological materials (UVCB) and consists of the dried leaves of the black to pulpred grape (Vitis viniferae folium). Polyphenols are typical components of grapes and belong to the most complex substance groups occurring in plants. In red vine leaves (Vitis vinifera), more than 100 different compounds are found. Most of these substances belong to one of the four main groups, either the flavonoids (such as flavonols), the anthocyanins, the procyanidins, or the phenol-carbonic acids. According to the French Pharmacopoeia, the dried leaves of grapevine contain at least 4% of total polyphenols and 0.2% of anthocyanins. Vine leaves contain a wide range of polyphenol flavonoids (up to 3.5%) including flavon(ol)- glycosides and glucuronides, quercetin-3-O-beta-D-glucuronide (most abundant of flavonoids), isoquercitrin, anthocyanins, oligomeric proanthocyanidins, catechin, epicatechin monomers and dimmers, and gallic acid. The phytoalexin trans-resveratrol, another polyphenolic substance belonging to the stilbene group, can also be found in grapevine. In vine leaves, organic acids such as malic acid, oxalic acid, and tartaric acid are also seen. Citric, fumaric, and succinic acid can be detected in the leaves only in traces. Compared to the grape berries, grape leaves are richer in the content of carotenoids and vitamin C (2). Compared to the marc of the grapes, vine leaves contain more than 20-fold the concentration of vasoactive polyphenols
