This study was conducted to investigate the antimicrobial activities of different solvent extracts of (MS) leaves against nine selected pathogenic microorganisms. The disc diffusion method was used to assess antimicrobial activity and determine minimum inhibitory concentrations (MIC). Methanol, and chloroform extracts showed significant inhibitory activity against and . The greatest antimicrobial activity, determined by lowest MIC values (62.5 μg/mL), was observed for inhibition of by the ethanol extract and by the methanol extract. The MICs of chloroform extract were 125 μg/mL against , Typhimurium, , , and . Water extract showed the lowest inhibition against these microorganisms, with MIC values of 250 μg/mL. The data presented in this study suggest that MS leaves have great potential in the development of food preservatives and antibiotic drugs.
本研究旨在调查（MS）叶的不同溶剂提取物对九种选定致病微生物的抗菌活性。采用纸片扩散法评估抗菌活性并确定最低抑菌浓度（MIC）。甲醇和氯仿提取物对（具体微生物名称缺失）和（具体微生物名称缺失）表现出显著的抑制活性。通过最低MIC值（62.5μg/mL）确定，乙醇提取物对（具体微生物名称缺失）和甲醇提取物对（具体微生物名称缺失）的抗菌活性最强。氯仿提取物对（具体微生物名称缺失）、鼠伤寒沙门氏菌、（具体微生物名称缺失）、（具体微生物名称缺失）和（具体微生物名称缺失）的MIC为125μg/mL。水提取物对这些微生物的抑制作用最低，MIC值为250μg/mL。本研究提供的数据表明，MS叶在食品防腐剂和抗生素药物的开发方面具有巨大潜力。
