Organic extracts (ethanol, petroleum ether and chloroform) of two medicinal plants Lawsonia inermis L. and Mimosa pudica L. were proven for antibacterial properties against 15 Gram-positive and Gram-negative human pathogenic bacteria. Among the three types of extracts tested, ethanol extract was found to possess maximum antibacterial activity. The diameter of the zone of inhibition of bacterial growth showed that Gram-negative bacteria are more sensitive than Gram-positive bacteria to plant extracts. Between the two plants species studied, Lawsonia inermis extract showed more antibacterial activity compared to Mimosa pudica extract.
两种药用植物无刺指甲花（Lawsonia inermis L.）和含羞草（Mimosa pudica L.）的有机提取物（乙醇、石油醚和氯仿）经证实对15种革兰氏阳性和革兰氏阴性人类致病细菌具有抗菌特性。在所测试的三种提取物类型中，发现乙醇提取物具有最大的抗菌活性。细菌生长抑制圈的直径表明，革兰氏阴性菌比革兰氏阳性菌对植物提取物更敏感。在所研究的两种植物物种中，无刺指甲花提取物比含羞草提取物表现出更强的抗菌活性。
