EXTRACTS OBTAINED FROM VITIS VINIFERA SEEDS AND/OR POMACE AND/OR GREEN GRAPES AND/OR STALKS AND USES THEREOF AS ANTIFUNGAL AGENTS

摘要

The invention relates to extracts obtained from viticultural and winemaking supply chain's waste matter, such as: Vitis vinifera seeds and/or pomace and/or green grapes and/or stalks chemically characterized (in terms of flavan-3-ols polymers and oligomers content and their reciprocal ratios) and obtained from cultivars subjected to controlled agronomic treatments and to their use as antifungal agents. The choice of the cultivar and of the standardized water and nitrogen agronomic treatments, allow obtaining extracts that are reproducible in their content in active components and to correlate the chemical features to the antifungal activity.
