This study was designed to characterize the phenolic profile and bioactivity of hydroalcoholic extracts from different cardoon (Cynara cardunculus L.) genotypes. The analytical work focussed on the inflorescence stigmas, owing to their application in cheese production. Nevertheless, other parts were concomitantly analysed aiming to define their possible use in related applications. Phenolic profiles obtained by LC-DAD-ESI/MSn showed significant differences among different cardoon genotypes, but apigenin and caffeoylquinic acid derivatives were generally the major molecules in all samples. Genotype influence has also been observed in relation to the antioxidant and antibacterial activities. Besides their strong antioxidant activity, the cardoon inflorescences showed satisfactory antibacterial activity, namely against Gram-positive strains, with particularly low MIC in Listeria monocytogenes. Overall, it was possible to identify the cardoon genotype (within the selected ones) providing the best standardized ingredient (stigma) with considerable added-value to be included in the process of cheese making.

这项研究旨在表征不同card蒲（Cynara cardunculus）的水醇提取物的酚谱和生物活性。L.）基因型。由于其在奶酪生产中的应用，分析工作着重于花序柱头。尽管如此，同时也对其他部分进行了分析，旨在定义它们在相关应用中的可能用途。通过LC-DAD-ESI / MSn获得的酚类谱显示不同菜豆基因型之间存在显着差异，但芹菜素和咖啡酰奎尼酸衍生物通常是所有样品中的主要分子。还已经观察到与抗氧化剂和抗菌活性有关的基因型影响。菜豆花序除了具有很强的抗氧化活性外，还表现出令人满意的抗菌活性，即针对革兰氏阳性菌株，单核细胞增生性李斯特菌的MIC特别低。总的来说，可以识别出菜豆基因型（在选定的菜豆基因型中），该基因型具有最佳的标准化成分（柱头），并具有可观的附加值，可包含在奶酪制作过程中。
