采用纸片扩散法研究了从蒙古族植物区系67种植物中提取的75种乙醇提取物对大肠杆菌、粪肠球菌、金黄色葡萄球菌、黄色微球菌和铜绿假单胞菌等5种微生物的抑菌活性。在所研究的植物提取物中，34种提取物分别对一种或多种微生物具有显著的抗菌活性。其中牡丹根提取液、麦冬全草提取液、紫云英全草提取液、仙人掌全草提取液等几种植物提取液具有较强的抑菌活性。从麦冬全草提取物和景天、牡丹、景天、水仙的乙酸乙酯提取物中分离得到的乙酸乙酯对金黄色葡萄球菌和黄色微球菌表现出较强的抑菌活性。
The antimicrobial activity of seventy five ethanol extracts obtained from 67 different kinds of plant species of the Mongolian flora were evaluated by means of the disc diffusion method against five species of microorganisms, Escherichia coli, Enterococcus faecalis, Staphylococcus aureus, Micrococcus luteus and Pseudomonas aeruginosa. Among the plant extracts examined, 34 kinds of extracts demonstrated significant antibacterial activity against one or more species of microorganisms, respectively. Especially, the root extract of Paeonia anomala, the whole herb extract of Myricaria alopecuroides, the whole herb extract of Comarum zalesovianum, the whole herb extract of Agrimonia pilosa and some other plant extracts demonstrated a particularly potent antimicrobial activity. The ethylacetate fractions obtained from the whole herb extract of Myricaria alopecuroides and from those of Sedum aizoon, Paeonia anomala, Sedum hybridum and Dasiphora fruticosa exhibited a particularly potent antibacterial activity especially against Staphylococcus aureus and Micrococcus luteus.
