Abstract

The antimicrobial activity of the methanol extracts of the dried flowering aerial parts of Stachys byzantina, S. inflata, S. lavandulifolia and S. laxa (Labiatae) were studied using the disc diffusion method and determination of minimum inhibitory concentration (MIC) values against Staphylococcus aureus, Streptococcus sanguis, Escherichia coli, Pseudomonas aeroginosa, Klebsiella pneumoniae, Aspergilus niger and Candida albicans. The extracts of plants exhibited concentration-dependent antibacterial activity against the bacteria tested. The extracts were more active against Gram-positive microorganisms. The extracts, however, did not show any antifungal activity.

摘要

采用纸片扩散法和最低抑菌浓度(MIC)测定法,研究了绵毛水苏、膨胀水苏、薰衣草叶水苏和疏花水苏(唇形科)干燥地上开花部分甲醇提取物对金黄色葡萄球菌、血链球菌、大肠杆菌、铜绿假单胞菌、肺炎克雷伯菌、黑曲霉和白色念珠菌的抗菌活性。植物提取物对受试细菌表现出浓度依赖性抗菌活性。提取物对革兰氏阳性微生物的活性更强。然而,提取物未表现出任何抗真菌活性。
