目的:研究新疆特色林果核桃、巴达木果壳乙醇提取物的抑菌特性。方法:用滤纸片法检验果壳乙醇提取物对金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌和变形杆菌的抑菌活性,通过液体培养基稀释法测定最低抑菌浓度。结果:巴达木乙醇提取物(25%乙醇提取10 h)对大肠杆菌有较好的抑菌效果,最低抑菌浓度(MIC)为25%;核桃乙醇提取物(25%乙醇提取24 h)对大肠杆菌有较好的抑菌效果,MIC为6.25%。结论:核桃、巴达木果壳乙醇提取物对受试菌具有较好的抑菌效果,为进行大规模开发利用提供了有效依据。
OBJECTIVE: To study the antimicrobial properties of ethanol extract of walnut and bark of Xinjiang fruit tree. Methods: The bacteriostatic activity of ethanol extract of shell of Chinese cabbage on Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Proteus was tested by filter paper method. The minimum inhibitory concentration was determined by liquid medium dilution method. Results: The ethanol extract of Bardalwood (25% ethanol for 10 h) had good antibacterial activity against Escherichia coli with a minimum inhibitory concentration (MIC) of 25%. The extract of walnut (25% ethanol for 24 h) Escherichia coli has good antibacterial effect, MIC was 6.25%. CONCLUSION: The ethanol extracts of walnut and balsam pear shell have good bacteriostatic effect on the tested bacteria, which provides an effective basis for the large-scale development and utilization.
