Grape juice and skin and seed extracts of Vitis vinifera var. Ribier black table grapes were found to be highly inhibitory towards Listeria monocytogenes. This grape juice was also active against all other Listeria species tested but not against Bacillus cereus, Salmonella Menston, Escherichia coli, Staphylococcus aureus or Yersinia enterocolitica. Fractionation of the extracts showed that the antilisterial activity was strongest in the polymeric phenolic fractions. Two different types of active compounds were identified: the red-pigmented polymeric phenolics from juice and skin showed pH-dependent antilisterial activity, while the unpigmented polymeric phenolics from the seed showed antilisterial activity which was independent of pH.
研究发现，葡萄汁以及欧亚种黑比诺酿酒葡萄的果皮和籽提取物对单核细胞增生李斯特菌具有高度抑制作用。这种葡萄汁对所有其他测试的李斯特菌属菌种也有活性，但对蜡样芽孢杆菌、门斯顿沙门氏菌、大肠杆菌、金黄色葡萄球菌或小肠结肠炎耶尔森氏菌没有活性。提取物的分级分离表明，抗李斯特菌活性在聚合酚类组分中最强。鉴定出两种不同类型的活性化合物：来自果汁和果皮的红色素聚合酚类表现出pH依赖性抗李斯特菌活性，而来自种子的无色素聚合酚类表现出与pH无关的抗李斯特菌活性。
