Waste from processing the far-east wild-growing plants - perspective sources of nutritional antioxidants

The maintenance of polyphenolic compounds and their antiradical activity in waste from processing grapes Amur (Vitis amurensis) and guelder-roses Sargent (Viburnum sargentii) are researched. It is shown, that the maintenance of polyphenolic compounds in extracts from extractions of grapes Amur and guelder-roses Sargent makes 10 % from the sum of extractive substances. Antiradical activity of the allocated polyphenolic complexes in modelling systems with ABTS + and ОН-radicals exceeds those at commercial polyphenolic antioxidant - pycnogenol. The researched kinds of waste can be a perspective source for reception the nutritional antioxidants showing electronophore and protonophore activity.
