Grapes represent one of the most produced fruit crops around the world leading to the generation of large amounts of vine-canes as a side product, with no current economically profitable application. However, vine-canes have been demonstrated to be natural sources of phenolic compounds with numerous health benefits associated, with several potential applications. Therefore, new ambitious applications focused on their re-use are needed, targeting a sustainable process that simultaneous produces functional products and mitigates the waste generation. This review gives to the readers a complete summary about the state of the art regarding the vine-canes extracts research. Vine-canes phenolic composition is addressed and related to the health benefits exhibited. This review comprises studies from the past two decades reporting the extraction processes to recover vine-cane phenolic compounds, including conventional and environmentally friendly technologies and discussing their advantages and disadvantages. The conditions that favour the extraction process for vine-cane polyphenols for each technique were also deeply explored for the first time, enabling to the reader apply only the best parameters to achieve the highest yields without huge investment in optimizations procedures. Furthermore, a correlation between the bioactive properties of the vine-cane extracts and their applications in multiple fields is also critically presented.
葡萄是全球产量最大的水果之一，由此产生了大量的葡萄藤副产物，目前还没有经济上有利可图的应用。然而，葡萄藤已被证明是酚类化合物的天然来源，具有许多与健康相关的益处，并具有多种潜在的应用。因此，需要新的有抱负的应用来重新利用它们，以实现可持续的过程，同时生产功能性产品并减少废物的产生。
本篇综述为读者提供了关于葡萄藤提取物研究现状的全面总结。本文介绍了葡萄藤的酚类成分，并探讨了其与健康益处的关系。本综述包括过去二十年来报道的从葡萄藤中回收酚类化合物的提取工艺的研究，包括常规和环保技术，并讨论了它们的优缺点。首次深入探讨了每种技术提取葡萄藤多酚的最佳条件，使读者能够仅应用最佳参数来获得最高产率，而无需在优化程序上投入大量资金。此外，还批判性地提出了葡萄藤提取物的生物活性特性与其在多个领域的应用之间的相关性。
