中文摘要: 研究乌梅醇提物对金黄色葡萄球菌的抑制作用。采用80%乙醇对乌梅进行提取，测定总黄酮含量为22.98 mg RE/ g FM，乌梅醇提物对金黄色葡萄球菌的最低抑制浓度为20 mg/mL，经醇提物处理后，金黄色葡萄球菌细胞壁、细胞膜通透性明显增加，培养液中核酸大分子物质、Ca2+含量和总漏出率增加，细胞代谢发生紊乱。研究为乌梅作为天然食品添加剂开发研究提供了科学参考。
Abstract:The antibacterial mechanism of Frucuts mume ethanol extracts against Staphylococcus aureus was studied.The total flavonoids content of ethanol extract was 22.98 mg RE/gFM.The antibacterial study showed that MIC of ethanol extract against Staphylococcus aureus was 20 mg/mL.After treated by Frucuts mume ethanol extract，the permeability of cell wall and membrane significantly increased，nucleic acid materials，Ca2+content and total leakage rate in the culture enhanced，and the cell metabolism of Staphylococcus aureus was disordered compared to the control.Consequently，the Frucuts mume ethanol extract showed the significant antibacterial effect against Staphylococcus aureus，suggesting its potential application as natural preservative in foods.
