摘要

目的: 研究9种蓼科植物的体外抗菌活性。方法: 采用纸片扩散法和多孔板法研究9种蓼科植物的不同提取物对金黄色葡萄球菌(SA)、耐甲氧西林的金黄色葡萄球菌(MRSA)和β-内酰胺酶阳性的金黄色葡萄球菌(ESBLs-SA) 的抑制活性。结果: 四季红甲醇提取物和四季红乙酸乙酯提取物质量浓度在50 g·L-1对SA

MRSA和ESBLs-SA的抑菌圈直径较大

其中四季红乙酸乙酯提取物对3种菌均有抑制作用

MIC全部为0.062 5 g·L-1;多孔板法中

辣蓼乙酸乙酯提取物(IC50 0.45 g·L-1)活性最好。结论: 实验证明蓼科植物提取物对SA

MRSA

ESBLs-SA有较好的抑制作用

尤其是四季红和辣蓼的抗菌活性较显著。

Abstract

Objective: To evaluate the antimicrobial activity of nine plants of Polygonaceae in vitro. Method: Disc diffusion methods and porous plate methods were used to evaluate the inhibitory activity of different extracts of nine Polygonaceae plants against Staphylococcus aureus (SA)

Methicillin-resistant Staphylococcus aureus (MRSA) and ESBLs-SA. Result: The results indicated that methanol extract of Polygonum capitatum D. Don and ethyl acetate extract of P. capitatum at the concentration of 50 g·L-1 had a larger inhibiting diameter than that of other extracts of plants

among them MIC in the ethyl acetate extract of P. capitatum against SA

MRSA and ESBLs-SA was 0.062 5 g·L-1. The ethyl acetate extract of P. hydropiper L. var hispidum (Jook. F.) Steward. showed the highest inhibitory effect (IC50 0.45 g·L-1) in porous plate methods. Conclusion: Results showed that nine plants extracts of Polygonaceae have better inhibitory activity against the tested bacteria

especially P. capitatum and P. hydropiper L. var hispidum (Jook. F.) Steward. showed more significant antimicrobial activity.
