The antimicrobial activities of crude methanolic extract of leaves of Acacia nilotica L., Albizia lebbeck L. and Mimosa himalayana Gamble belonging to family mimosaceae were investigated in this research work. Antibacterial activity was studied by agar well diffusion method against one gram-positive Bacillus subtilis and three gram-negative Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia. Crude extract of all plants showed best activity against gram-negative bacterial strains while minor inhibition zones were found against gram positive bacterial strains. Antifungal activity of crude plant extract was screened by agar tube dilution method against Aspergillus nigar and Aspergillus flavus. These results showed that these plants extracts have potential against bacterias, while against fungi their activity is not much effective.
本研究工作对含羞草科的阿拉伯胶树、阔荚合欢和喜马拉雅含羞草叶片的甲醇粗提物的抗菌活性进行了研究。采用琼脂孔扩散法研究了其对一株革兰氏阳性菌枯草芽孢杆菌以及三株革兰氏阴性菌铜绿假单胞菌、大肠杆菌和肺炎克雷伯菌的抗菌活性。所有植物的粗提物对革兰氏阴性菌菌株表现出最佳活性，而对革兰氏阳性菌菌株的抑菌圈较小。采用琼脂试管稀释法筛选了植物粗提物对黑曲霉和黄曲霉的抗真菌活性。这些结果表明，这些植物提取物对细菌有潜在作用，而对真菌的活性不太有效。
