Hops are widespread as a wild plant in almost all Northern and Central Italy, and the characterization of wild populations is attracting considerable interest in verifying their potential use. The development of hops as agricultural crop can be an interesting opportunity, both for farms that would have available a new crop to be included in the crop system and for craft breweries interested in characterizing beers with local raw materials. In the present work, 14 wild hop accessions coming from various Italian locations were characterized and compared with 2 commercial varieties (Cascade and Hallertau Taurus) grown in the same environments. The cones were analyzed to measure the content of α- and β-acids, polyphenols, flavonoids, and the anti-radical power. The α-acid content of wild hops was generally low, while the β-acid content was very variable and quite high in some samples. The content in polyphenols and flavonoids and the antiradical power were high and generally similar to those of the commercial varieties. Therefore, the analyzed genotypes are not very suitable for use as bitter hops in beer production, while further analysis may indicate a possible use as aroma hops, or for herbal and pharmaceutical purposes, thanks to their antioxidant content.
啤酒花作为一种野生植物在意大利北部和中部几乎所有地区都广泛分布，野生种群的特性研究对于验证其潜在用途正引发相当大的关注。将啤酒花发展成为农作物，对于那些在作物种植体系中有新作物可供选择的农场以及对用当地原料酿造啤酒感兴趣的精酿啤酒厂来说，可能是一个有趣的机遇。在本研究中，对来自意大利不同地点的14份野生啤酒花种质进行了特性分析，并与在相同环境下种植的2个商业品种（卡斯卡特和哈拉道金牛）进行了比较。对酒花球果进行分析，以测定α-酸和β-酸、多酚、黄酮类化合物的含量以及抗自由基能力。野生啤酒花的α-酸含量普遍较低，而β-酸含量变化很大，在一些样品中相当高。多酚和黄酮类化合物的含量以及抗自由基能力较高，且总体上与商业品种相似。因此，所分析的基因型不太适合用作啤酒生产中的苦味啤酒花，不过由于其抗氧化成分，进一步分析可能表明其可用作香花啤酒花，或用于草药和制药用途。
