This study aims to assess the microbial load of some medicinal plants (Matricaria chamomilla, Achillea millefolium, Ocimum basilicum, Calendula officinalis, Tilia cordata, Hypericum perforatum) commonly used as medicinal teas.
A total of 24 samples collected from the local market, as well as from the spontaneous flora of Galati County, were analyzed in terms of the total number of germs, the content of coliform bacteria, yeasts and molds, and the presence of specific pathogenic bacteria (Escherichia coli, Bacillus cereus, Coagulase-positive Staphylococcus, Salmonella spp.).
The values obtained for total number of germs, yeasts and molds were in accordance with the limits set by the European Pharmacopoeia for plant products to which hot water is added before use. In the case of specific pathogenic bacteria, the presence of E. coli was confirmed in 41.66% of the samples, the presence of Coagulase-positive Staphylococcus in 16.66% of the samples, and the presence of Bacillus cereus in 33.33% of the samples. Salmonella spp. was absent in all samples.
The study highlights a certain microbial load of medicinal plants analyzed, emphasizing the importance of quality control in all stages of production.
本研究旨在评估一些常用作药茶的药用植物（洋甘菊、蓍草、罗勒、金盏花、心叶椴、贯叶连翘）的微生物负荷。
对从当地市场以及加拉茨县自然植物群中采集的共24个样本进行分析，检测其细菌总数、大肠菌群、酵母菌和霉菌含量以及特定病原菌（大肠杆菌、蜡样芽孢杆菌、凝固酶阳性葡萄球菌、沙门氏菌属）的存在情况。
所获得的细菌总数、酵母菌和霉菌的值符合欧洲药典对使用前添加热水的植物产品所设定的限值。在特定病原菌方面，41.66%的样本中证实存在大肠杆菌，16.66%的样本中存在凝固酶阳性葡萄球菌，33.33%的样本中存在蜡样芽孢杆菌。所有样本中均未检测到沙门氏菌属。
该研究突出了所分析药用植物存在一定的微生物负荷，强调了生产各阶段质量控制的重要性。
