新疆部分特色林果果壳的抗菌活性研究

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。

Study on Antibacterial Activity of Hull Extracts from Xinjiang Characteristics Wood Fruits Nuts

Objective： To research the antimicrobial effects of ethanol extracts from wood fruit nut hull of Xinjiang walnut and badamu.Methods： The antibacterial experiments were carried out by paper disc and continuous dilu-tion of culture medium method on 4 tested strains.Results： Based on the experiments,the ethanol extract of badam（10 h,25% ethanol） and walnut（24 h,25% ethanol） had better bacteriostatic effect on Escherichia coli with MIC of 25% and 6.25% respectively.Conclusion： The results showed that the ethanol extracts aganist 4 tested strains were successful,which supplied a valid evidence for larger scale exploition.
