This study investigated the antibacterial and in vitro antidementia effects of aronia (Aronia melanocarpa) leaf extracts from 3 cultivars (Nero, Viking, and McKenzie) collected at three different stages of maturity (young, harvest, and old). Bacillus cereus was susceptible to the old leaves of cultivars McKenzie and Nero, whereas Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria innocua were not inhibited by any of the extracts. Growth of B. cereus was inhibited by cv. McKenzie, resulting in increased lag time, whereas Nero had both an inhibitory and an inactivation effect. Except for cv. Viking at harvest stage, the acetylcholinesterase and butyrylcholinesterase inhibitory activity of aronia leaf extracts were about 60–70 and 70–80%, respectively. Therefore, aronia leaf is a natural resource with a potentially potent antidementia effect, besides antibacterial activity.

这项研究调查了在成熟的三个不同阶段（年轻，收获和旧）收集的3个品种（Nero，Viking和McKenzie）中的Aronia（meliacarpa ）叶提取物的抗菌和体外抗痴呆作用。蜡状芽胞杆菌对麦肯齐和Nero品种的老叶子敏感，而大肠杆菌O157：H7，鼠伤寒沙门氏菌和无毒李斯特菌均不受任何提取物的抑制。蜡状芽孢杆菌的生长被简历抑制。McKenzie导致滞后时间增加，而Nero同时具有抑制作用和失活作用。除了简历。维京人在收获期时，阿龙尼亚叶提取物的乙酰胆碱酯酶和丁酰胆碱酯酶抑制活性分别约为60％至70％和70％至80％。因此，除了具有抗菌活性之外，无花果叶是一种具有潜在抗痴呆作用的天然资源。
