    Abstract: The invention describes the extraction method to obtain the highest amount of resveratrol from wasted biomass produced by grapes processing. Resveratrol, which is found rich in the grapes, especially in grape skin and seed, is one of the most potent antioxidant, and can help to fight cell-damaging free radicals and promote cardiovascular health. Based on the most performing extraction methods to obtain resveratrol from plant material, the invention provides the optimized method of extracting the highest amount of resveratrol from wasted biomass from grapes processing.

    Abstract translation: 本发明描述了从葡萄加工产生的废弃生物质中获得最高量的白藜芦醇的提取方法。 白藜芦醇被发现富含葡萄,尤其是葡萄皮和种子,是最有效的抗氧化剂之一,可以帮助抵抗破坏细胞的自由基和促进心血管健康。 基于从植物材料获得白藜芦醇的性能最佳的提取方法,本发明提供了从葡萄加工废物生物质中提取最高量的白藜芦醇的优化方法。
