Raspberries, derived from different cultivar varieties, are a popular ingredient of everyday diet, and their biological activity is a point of interest for researchers. The ethanol-water extracts from four varieties of red (Rubus idaeus'Ljulin', 'Veten', 'Poranna Rosa') and black(Rubus occidentalis'Litacz') raspberries were evaluated in the range of their antimicrobial properties as well as phenolic content - sanguiin H-6, free ellagic acid and anthocyanins. The antimicrobial assay was performed with the use of fifteen strains of bacteria, both Gram-negative and Gram-positive. The antimicrobial activity of the extracts varied and depended on the analysed strain of bacteria and cultivar variety, with the exception of Helicobacter pylori, towards which the extracts displayed the same growth inhibiting activity. Two human pathogens Corynebacterium diphtheriae and Moraxella catarrhalis proved to be the most sensitive to raspberryextracts. Contrary to the extracts, sanguiin H-6 and ellagic acid were only active against eight and nine bacterial strains, respectively. The determined MIC and MBC values of both compounds were several times lower than the tested extracts. The highest sensitivity of Corynebacterium diphtheriae to extracts from
both black and red raspberries may be due to its sensitivity to sanguiin H-6 and ellagic acid.
来自不同品种品种的覆盆子是日常饮食的热门成分，它们的生物活性是研究人员感兴趣的一 点。来自四种红色（Rubusidaeus'Ljulin'，'Veten'，'Poranna Rosa'）和黑色（悬钩子） 的乙醇水提取物 occidentalis'Litacz'）覆盆子进行了评估，其抗菌性能以及酚含量 - sanguiin H-6，游离鞣花酸和花青素。使用十五种细菌菌株（革兰氏阴性和革兰氏阳性） 进行抗微生物测定。除幽门螺杆菌外，提取物的抗微生物活性各不相同，取决于所分析的细 菌菌株和栽培品种，提取物对此表现出相同的生长抑制活性。两种人类病原体白喉棒状杆菌（Corynebacterium diphtheriae）和卡他莫拉菌（Moraxella catarrhalis）被证明是对覆盆子最敏感的提取物。与提取物相反，sanguiin H-6 和鞣花酸仅分别对八种和九种细菌菌 株有活性。两种化合物的测定的 MIC 和 MBC 值比测试提取物低几倍。白喉棒状杆菌对黑 色和红色覆盆子提取物的最高敏感性可能是由于它对三聚氰胺 H-6 和鞣花酸的敏感性。
